Request for Non-Substantive Change to the 2020 Census Local Update of Census
Addresses Operation (LUCA)
OMB Control No. 0607-0994
U.S. Department of Commerce
U.S. Census Bureau

Purpose
The 2020 Census Local Update of Census Addresses Operation (LUCA) is the only opportunity
offered to tribal, state, and local governments to review and comment on the U.S. Census
Bureau's residential address list for their jurisdiction prior to the 2020 Census. The Census
Bureau relies on a complete and accurate address list to reach every living quarter and associated
population for inclusion in the census. The Census Address List Improvement Act of 1994
(Public Law 103-430) authorizes the LUCA Operation. On December 15, 2016, the Office of
Management and Budget (OMB) approved the 2020 Census LUCA information collection.
Background
On May 11, 2018, the Census Bureau received pre-authorization from OMB to send emails or
letters to groups of partners to document issues and provide additional instructions they needed
to complete their address review. The Census Bureau is now submitting this non-substantive
change (NSC) request:
1) To supply documentation of all the changes and messages sent to groups of partners
during the LUCA Review Phase between May 2018 and April 2019.
2) To add 11 out of 26 materials for the LUCA Feedback Phase.
The Census Bureau documented two categories of changes applicable to the LUCA Review
Phase: provision of additional instructions or clarifications and expansion of the method of
contacting participants from letter to email. Participants with a functional email account
receive instructions by email. Per the federal register notices, the Census Bureau was going to
contact LUCA participants by physical mailing addresses. By expanding the method of
contacting participant, the Census Bureau saves time and money. (See Attachment - Table 1 for
more information.)
In addition, the Census Bureau is submitting 11 new materials such as quick start guides, letters,
and forms that contain instructional and informational guidance for conducting the LUCA
Feedback Phase (Table 2). Participants will use the instructions and guidance to provide address
feedback to the Census Bureau. Once OMB reviews and approves the current materials, the
Census Bureau will submit the remaining feedback materials through an NSC by June 19, 2019.
There is no substantive change to the operation resulting from this change.
Burden
The burden of the 2020 Census LUCA is unchanged by this update.

LUCA – Submitting all intended addresses using GUPS
U.S. Census Bureau
Tue 5/8/2018 03:52 PM

Attention LUCA GUPS Users:
Addresses added or modified without structure coordinates (map spots) may be excluded from your LUCA submission if you don’t save your
edits, close the GUPS software, and restart GUPS prior to exporting. Please follow the instructions below to ensure that your LUCA submission
to the Census Bureau contains all of the addresses that you have added, edited, deleted or marked as “out of jurisdiction.”
We recommend that all partners reviewing addresses using the GUPS software perform the following actions, in the order prescribed below,
before exporting and submitting your file.
1. Finish editing your Census Address List.
2. Run the Address Review Tool and correct any addresses that need correction.
3. Save your edits.
4. Close GUPS.
5. Reopen GUPS and your project via the “Open Recent” button on the Map Management window.
6. Select the “Export to Zip” button from the LUCA Toolbar.
7. Submit zip files through the Secure Web Incoming Module (SWIM) at https://respond.census.gov/swim/
If you have already submitted your LUCA file to the Census Bureau, please review the file to ensure that all address records you intended to
submit were sent to the Census Bureau. If not, or if you are unsure, starting with step 5 above: reopen your project in GUPS, export the file and
resubmit the file through SWIM.
For further instructions on how to successfully export your LUCA submission, review the LUCA GUPS FAQ document .
If you have any questions, please call the Census Bureau at 1-844-344-0169.

LUCA - Reviewing ungeocoded records in GUPS
GEO 2020 LUCA (CENSUS/GEO)

D-2077

No. 0607-0994: Approval Expires 12/31/2019

Attention: You may not be able to see some of the addresses in your LUCA ﬁle! This email explains whether you
might be aﬀected and if so, the options to resolve it.
LUCA Participant,
It has come to our attention that due to a Census Bureau data error, county governments participating in LUCA
are unable to view the ungeocoded census addresses associated with their community while using the
Geographic Update Partnership Software (GUPS). The ungeocoded addresses are included in the LUCA address list
provided to each participant, but the GUPS is not displaying those addresses.
As a reminder, ungeocoded addresses are addresses where the Census Bureau is unable to determine which
census tract and census block the address is located in. In most cases, these are new addresses where the Census
Bureau has not added the roads, street names or address ranges to our maps that would allow for a precise
location to be established.
If your county is using GUPS, and would like to review the ungeocoded addresses associated with your county, the
procedure is described in the Frequently Asked Questions on our website:
https://www2.census.gov/geo/pdfs/partnerships/luca/2020LUCA_GUPS_FAQ.pdf
An additional two weeks of review time will be added to your 120-day review period to ensure you have enough
time to complete your LUCA review.
If you are using GUPS and would prefer that the Census Bureau redeliver a corrected address ﬁle that will allow
GUPS to display the ungeocoded records without using the procedure referenced above, then contact the
Census Bureau at 1-844-344-0169. Note, if you choose to receive a corrected address ﬁle, we will extend your
120-day review period by two weeks.
If you have already submitted your LUCA updates to the Census Bureau, you are welcome to review the
ungeocoded addresses using either method described above, and provide them to the Census Bureau as either a
supplemental ﬁle of just the ungeocoded updates or a replacement ﬁle containing all of your updates for LUCA.
An additional two weeks of review time will be added to your 120-day review period to ensure you have enough
time to complete your LUCA review.
If you are not using GUPS, you can ﬁnd the ungeocoded addresses on your LUCA address list by searching for
those addresses where the Census State, Census County, Census Tract, Census Block and GEOID ﬁelds are blank.
If you have any questions, please call the Census Bureau at 1-844-344-0169.

Importance: High

ATTENTION LUCA PARTICIPANT:
As you work to prepare your LUCA submission, this message serves as a reminder that you may NOT email your LUCA submission to the U.S.
Census Bureau. Email is not a secure method of transfer for Title 13 materials. Participants must use the Secure Web Incoming Module (SWIM)
to submit their files or must create a CD/DVD of their files for shipment to ensure a secure transfer of information. Follow the Title 13 guidelines
and instructions in Chapter 7 and Appendix A of the Digital Respondent Guide (D-2032) to ensure a secure submission. Participants can locate
the Digital Respondent Guide on the LUCA website within the “What are LUCA Review Materials?” section or with their original review materials.
If you encounter difficulties with your SWIM account or have other LUCA questions, contact the Geographic Partnership Support Desk at 1-844344-0169 for assistance.

BACKGROUND
A.

General Information

The 2020 Census Local Update of Census Addresses Operation (LUCA) is a voluntary decennial census
operation. LUCA is the only opportunity prior to the 2020 Census for tribal, state, and local governments
(including the District of Columbia and Puerto Rico) to review and update the Census Bureau’s
residential address list for their jurisdiction. The Census Bureau relies on a complete and accurate
address list to reach every living quarters and associated population for inclusion in the census. The
Census Address List Improvement Act of 1994 (Public Law 103-430) authorizes the LUCA operation.
Refer to for
more information.
In accordance with the law, the LUCA Feedback Phase provides participating governments with detailed
feedback materials that document which local address updates the Census Bureau processed. LUCA
participants may dispute the processing results of certain addresses, only if those addresses meet
certain eligibility criteria. Participants must file their Appeal within 45 calendar days after the receipt of
the feedback materials. Appeals filed after the deadline will be denied. Filing an Appeal is optional and is
not a requirement of LUCA.
IMPORTANT: The final Federal Register notice is included with the feedback materials and is available
on the LUCA website, , for participants to consult before beginning their review.

Census Bureau Processing of LUCA submissions

The Census Bureau reviewed all addresses submitted by LUCA participants during the LUCA Review
Phase and processed those meeting the defined criteria. In addition, the Census Bureau made necessary
corrections and updates to the census maps from the LUCA Review Phase submissions.

Confidentiality and Security

All of the requirements and guidelines for protecting the Census Bureau’s confidential Title 13, United
States Code (U.S.C.) materials followed for the LUCA Review Phase are applicable to the LUCA feedback
materials.1 All participants are required to sign a Confidentiality Agreement Form in accordance with
Title 13, U.S.C. to maintain the confidentiality of the census address information they received from the
Census Bureau for review. Participants are required to have the means to secure the Census Address List
containing Title 13 information.
Persons who signed the D-2005 – Confidentiality Agreement Form for the LUCA Review Phase, are not
required to sign the form again. However, anyone who will review or have access to the confidential
Title 13 feedback materials and has not already signed form D-2005 must read and agree to abide by the
Confidentiality and Security Guidelines, included as Appendix A, and must sign the Confidentiality
Agreement Form before reviewing the materials. A blank D-2005 – Confidentiality Agreement Form is

Title 13, U.S.C provides for the confidential treatment of census-related information, including individual addresses and map spots. Title
13 requires that all liaisons, reviewers, and anyone with access to Title 13 materials abide by the Confidentiality and Security Guidelines.
Title 13 also requires that the Census Bureau maintain the confidentiality for all of the information that it collects.

included in this respondent guide as Appendix B. This form is also available on the LUCA website at
.
The D-2202 – Detailed Feedback Address List is Title 13 protected material. It is included, in printed form
only, in the feedback materials for all participants whose final format during the LUCA Review Phase was
the Paper Address List. In addition, if a participant’s final format for maps was PDF maps, the Title 13
protected, small format block maps are on the enclosed DVD. The PDF maps require a password to
decrypt and open. The case-sensitive password, necessary to open the small format block maps, is
different from the password used during the Review Phase. It arrives separately and prior to receiving
the feedback materials. Keep the password letter (D-2280) secure.
Following the LUCA Feedback Phase or a possible Appeal, at the conclusion of the 2020 LUCA operation,
the LUCA liaison must verify the destruction (preferred) or return to the Census Bureau all Title 13
materials and copies by signing and returning the D-2012 – Destruction or Return of Title 13, U.S.C.
Materials Form. A blank form is included as Appendix C. This form is also available online at the LUCA
website. Additional information or assistance is available, toll-free, by phone at (844) 344-0169 or by
email at [email protected].

Entity Identification Codes

All local government entity codes, also known as the “EntityID,” appearing in the feedback materials
have a two-letter code identifying the type of entity. County, place, and minor civil division codes
include the state two-digit Federal Information Processing Series (FIPS) numeric code. Minor civil
divisions also include the county three-digit FIPS numeric code. See Table 1 for information regarding
the entity identification codes.

County: CO42085 (Mercer County, Pennsylvania).



Place: PL0100124 (Abbeville city, Alabama).



Minor Civil Division: MC4208567472 (Salem Township, Mercer County, Pennsylvania).

Tribal government entity codes contain a unique 12-character alphanumeric identification code assigned
by the Census Bureau that identifies the tribe and its associated geographic area. An example of a 12character tribal identification code, TR0013TA0185, where TR0013 is the six-character tribal code that
represents the Utu Utu Gwaitu Paiute Tribe of the Benton Paiute Reservation and TA0185 is the sixcharacter tribal geographic area code that represents Benton Paiute Reservation, the geographic area
associated with the Utu Utu Gwaitu Pauite Tribe. This 12-character code is the “EntityID” for tribal
governments.

CHAPTER 1

2020 CENSUS LUCA FEEDBACK AND APPEALS
INTRODUCTION

This chapter provides introductory information on the materials paper address participants receive as
part of the LUCA Feedback Phase based on the final format of the LUCA Review Phase.
IMPORTANT: For participants needing visuals and detailed examples, the 2020 Census Local
Update of Census Addresses Operation (LUCA) Respondent Guide; Paper Address List
Format (D-2031) distributed during the LUCA Review Phase includes additional graphics
and information. Locate the respondent guide on the LUCA website,
, and
use it to supplement instructions in this material.

1.1

Feedback Materials

The Census Bureau provides LUCA Feedback Phase materials to eligible governments beginning in July
2019 and ending in September 2019. Unless a participant declined feedback, the Census Bureau
provides LUCA feedback materials for jurisdictions that submitted address updates after reviewing and
applying each properly formatted address update to the Census Address List and adding any new
addresses not already included. The Census Bureau verified the participant suggested address updates
(additions, corrections, deletions, etc.) to ensure that all address updates and additions exist and that
they are in the correct census block. Participants that reviewed the Census Address List, agreed with its
contents during the LUCA Review Phase, and asked to receive feedback also receive LUCA Feedback
Phase materials.
The Census Bureau provides feedback materials according to the final format that the participant
selected for the LUCA Review Phase. For paper address list participants, there are three product
preferences described in the detailed sub-sections below. Regardless of the product preference, the
feedback materials include:2


Feedback Address Update Summary Report (D-2201) — displays the tallies of actions taken by
the Census Bureau for all the address updates submitted by an entity.



Detailed Feedback Address List (D-2202) — shows all accepted (i.e., properly formatted) address
record updates submitted by the participant and a feedback processing code identifying a
specific action taken by the Census Bureau on that address record. This address list also
identifies any address records not commented on and deleted from the original Census Address
List by a different census operation or another level of government participating in LUCA.



Feedback Address Count List (D-2209) — contains the number of residential housing unit (HU)
and group quarters (GQ) addresses on the LUCA Review Phase Census Address List and the
current number of HU and GQ residential addresses for each Census block within the
participant’s jurisdiction.

For participants that either told us “no changes” on the D-2079 or D-2084 and had no records deleted by other LUCA participants or
other census operations or for those that submitted a file that could not be processed and had no records deleted by other LUCA
participants or other census operations, there are no addresses to review or Appeal. These participants receive a paper insert, the D2282, instead of a Detailed Feedback Address List that explains why. If they receive a DVD as part of their materials, a corresponding
portable document format (PDF) file, 2020LUCA_FB_insert.pdf, will be present on their DVD.

2020 Census LUCA Feedback Respondent Guide



Feedback Block to Map Sheet Relationship List (D-2210) — identifies the large format parent
map sheet(s) or inset sheet(s) on which each census block is located. This product is for
participants that selected either paper or paper/Portable Document Format (PDF) maps. The
sort for this product is by census tract number and census block number in ascending order.



Feedback Maps — may include feature updates provided by the submitting entity, other LUCA
participants, and/or other updates found by the Census Bureau during other census operations.
The Census Bureau provides maps or shapefiles in the final format selected for the LUCA Review
Phase materials.
o Large format paper maps — large format (36”x32”) paper maps that may include one or

Converting Comma Delimited Text Files

The Feedback Address Count List .csv file described above is a comma-delimited text file provided to
participants receiving a DVD (i.e., those receiving small format block maps or digital maps). Many paper
address participants may only need the printed version, but for those that misplace their printed copy or
need an additional copy, they may use this digital version to print another copy or to sort and filter the
digital version. The Feedback Address Count List is not Title 13 material.
Most commercial spreadsheet and database programs can open the .csv files (e.g., Microsoft Excel®,
Microsoft Access®, etc.).4 However, in order to read the file contents properly, participants must import
the file rather than opening it. The following set of bullets use Excel 2016 to describe the proper way to
open the .csv files.5


Open a new Excel spreadsheet.



Select the “Data” tab. Click on “Get External Data.” Select “From Text.”



Navigate to the folder on the local computer containing the Feedback Address Count List and
click on the file. See the LUCA Feedback Paper Quick Start Guide (D-2241) for that information.



When the file highlights, select “Import” at the bottom of the screen.



The “Text Import Wizard – Step 1 of 3” window opens in Excel, check the “My data has
headers” box and select “Next.”



In Step 2 of 3, select “Comma” for Delimiters. From the “Text qualifier” drop-down menu,
select “{none}.” Select “Next” at the bottom of the screen.



In Step 3 of 3, hold the “Shift” key and scroll to the end of the columns. The columns will
highlight black.



Select the “Text” radio button. Define all field types as Text, including numeric fields such as
state, county, census tract number, census block number, and GEOID to account for leading
zeros that are important for accurate geocoding.



Click “Finish” at the bottom of the window.

After a successful import, the following table, Table 3, shows the maximum character length of each
field, the field name, and a description of the field.

CHAPTER 2

REVIEWING THE 2020 CENSUS LUCA FEEDBACK
MATERIALS AND PROCESSING CODES

This chapter provides detail on the content within the feedback materials and lays the foundation for
conducting a review of the materials. It devotes a section to describing the detailed feedback processing
codes and identifying which records are eligible for Appeal based on their feedback processing code.

2.1

Feedback Address Update Summary Report (D-2201)

The Census Bureau provides a printed copy of the Feedback Address Update Summary Report (D-2201)
to participants with their feedback materials package. Participants receiving small format block maps or
digital maps will also find a portable document format (PDF) file of this report on their enclosed DVD.
The report summarizes the Census Bureau processing performed on the address records submitted by
participants during the LUCA Review Phase. This report displays the tallies of actions taken by the
Census Bureau for all of the address updates that the participant submitted and the total number of
address records on the original Census address list that were deleted by a different census operation or
another level of government participating in LUCA. See Figure 1 for an example of the report.
Section “A” of the summary report contains the total number of address records submitted to the
Census Bureau for the LUCA Review Phase, the total number of address records submitted that were
processed, and the total number of address records submitted without required information and were
not processed. Unprocessed addresses include those with blank or invalid action codes, addresses
submitted without geographic information such as the census tract and block numbers or the latitude
and longitude coordinates, or non-city style addresses without a map spot or latitude and longitude
coordinates. The total number of participant address records submitted for processing (e.g., 100) equals
the total number of address records processed (e.g., 91) and the total number of address records not
processed (e.g., 9).
IMPORTANT: The total number of submitted address records processed by the Census Bureau (e.g., 91
records in the case of Figure 2) equates to the number of records that appear in the
Detailed Feedback Address List.
Section “B” of the report displays the tallies of actions taken by the Census Bureau for all the processed
address records submitted with valid action codes and map spot/coordinates (or geocodes). The total
number of address records accepted as requested (e.g., 61) and the total number of address records not
accepted as requested (e.g., 30), equals the total number of address records submitted and processed
(e.g., 91) as shown in Section “A” of the report.
Section “C” of the report contains address records not commented on, but deleted from the original
Census Address List by a different census operation or another level of government participating in
LUCA. Review Section 2.2.3 for information on these deleted records.

2.2

Detailed Feedback Address List (D-2202)

The Census Bureau provides the Detailed Feedback Address List (D-2202) to participants as part of their
feedback materials in order to see the disposition of each submitted address record processed by the
U.S. Census Bureau

2020 Census LUCA Feedback Respondent Guide

Census Bureau. Participants use the Detailed Feedback Address List to determine which address records
are eligible for Appeal and denote them accordingly. This material shows all usable address record
updates submitted by the participant, processed by the Census Bureau, and a feedback processing code
identifying a specific action taken on that address record. In addition, the list contains any addresses
that were on the participant’s Census Address List during the LUCA Review Phase, but subsequently
deleted by a different census operation or another level of government participating in LUCA.
The printed Detailed Feedback Address List is on 8 ½ x 14 inch (legal size) paper, with six addresses per
page. To facilitate the participant’s feedback review, the Census Bureau provides the Detailed Feedback
Address List sorted based on the following order of the Feedback Code column: X01, R03, A01, A02, A03,
R01, and R02. Within each feedback processing code, the sort is by the LUCA Review Phase sort order
(i.e., tract/block or street name/house number). Performing this dual sort promotes the records eligible
for Appeal to the beginning while retaining the reference to the sort from the LUCA Review Phase
materials. The heading area of this material identifies the sort option. See Figure 2 for an example of this
material for a fictitious entity.
IMPORTANT: The Detailed Feedback Address List is the only editable material for the LUCA Feedback
Phase and the “Appeal Flag” column in the Detailed Feedback Address List is the only
editable column.
During the LUCA Review Phase, if participants determined the Census Address List was correct, had no
address updates, and returned either form D-2079 – No Updates or Changes to Addresses Form or form
D-2084 – Submission Deadline Form indicating that they wanted to receive the LUCA Feedback Phase
materials, their Detailed Feedback Address List contains only the addresses deleted by a different census
operation or another level of government participating in LUCA. If there were no addresses deleted
since the LUCA Review Phase, participants do not receive a Detailed Feedback Address List. Instead they
receive a paper insert (D-2282), mentioned as the footnote in Section 1.1, which notifies them that they
did not have any addresses eligible for Appeal.

Understanding the Feedback Processing Codes

The feedback processing codes in the Detailed Feedback Address List indicate the results of the Census
Bureau processing of participants records submitted during the LUCA Review Phase. Table 4 identifies
the feedback processing code assigned to the records submitted by a participant. The second column
indicates if the code is eligible for Appeal. The third column gives the Census Bureau’s result of the
processing, including information regarding the acceptance or rejection of the participant’s update and
a decision to include or exclude the address from the 2020 Census.

Description
Address OUT of the Census: The Census Bureau will exclude this address
from the 2020 Census for your jurisdiction. This address was not updated as
part of your LUCA review, but has been deleted from the 2020 Census
Address List by another level of government participating in LUCA or a
different census operation.
Address OUT of the Census: The Census Bureau will exclude this address
from the 2020 Census for your jurisdiction, and rejects your LUCA update.
Address IN the Census, Same Block: The Census Bureau will include this
address in the 2020 Census for your jurisdiction in the same block, and
accepts your LUCA update.
Address IN the Census, Different Block: The Census Bureau will include this
address in the 2020 Census for your jurisdiction in a different block, and
accepts your LUCA update.
Address OUT of the Census: The Census Bureau will exclude this address
from the 2020 Census for your jurisdiction, and accepts your LUCA update.
Address IN the Census, Same Block: The Census Bureau will include this
address in the 2020 Census for your jurisdiction in the same block, and
rejects your LUCA update.
Address IN the Census, Different Block: The Census Bureau will include this
address in the 2020 Census for your jurisdiction in a different block, and
rejects your LUCA update.

The Feedback Code column of the Detailed Feedback Address List contains the code that specifies if the
Census Bureau accepted or rejected the action submitted by the participant. For example, A01, A02, and
A03 indicates the Census Bureau accepted the address update. These three feedback processing codes
are not eligible for Appeal. Both A01 and A02 records remain in the 2020 Census enumeration universe
and therefore are ineligible for Appeal while the A03 reflects an accepted update that excludes an
address from the 2020 Census enumeration universe (i.e., accepted D, N, and J LUCA actions).
The three “R” feedback processing codes (R01, R02, and R03) indicate the Census Bureau rejected the
updated addresses. Only the R03 is eligible for Appeal. Both R01 and R02 records remain in the 2020
Census enumeration universe and therefore are ineligible for Appeal.
In addition to records submitted by a participant, the Detailed Feedback Address List may include
addresses that were in the Census Address List during the LUCA Review Phase (not commented on by
the participant), but deleted by a different census operation or another level of government
participating in LUCA. These addresses receive an X01 feedback processing code and are eligible for
Appeal.
IMPORTANT: Only addresses assigned with feedback processing codes of X01 or R03 are eligible for
Appeal because they are not part of the 2020 Census enumeration universe.

2.2.4

Feedback Processing Code Examples

This section provides only a few examples for each feedback processing code. It documents some of the
most common scenarios encountered during the Census Bureau’s processing of LUCA Review Phase

U.S. Census Bureau

2020 Census LUCA Feedback Respondent Guide

submissions. This list of examples is not a comprehensive list of all the scenarios that lead to the
assignment of feedback processing codes.
X01 – Address removed from the 2020 Census. The Census Bureau will exclude this address from the
2020 Census for the participant’s jurisdiction. A different census operation or another level of
government participating in LUCA deleted the address. This address was not updated as part of the
participant’s LUCA Review Phase work. (Appeal eligible.)


If a state participant deleted a record that no nesting entity participants (county, minor civil
division, place, and American Indian Area) commented on, the nesting entity participants would
see this address as an X01.



If a participant did not update the address but an update from a different census operation
deleted it, the participant would see the address as an X01.

R03 – Address is not in the 2020 Census. The Census Bureau will exclude this address from the 2020
Census for the participant’s jurisdiction and rejects the LUCA update. (Appeal eligible.)


Participant adds an address (an A action) to an area where evidence of housing does not exist,
or the Census Bureau processing determines the address is not residential. The Census Bureau
rejects the A action and excludes it from the 2020 Census enumeration universe. This action
would receive an R03. The participant can Appeal the address record for inclusion in the 2020
Census enumeration universe.



A county participant corrects (a C action) the geocode of an address, but the place participant
marks the same address as non-residential (an N action). The Census Bureau accepts the place
participant’s action, removes the address record from the 2020 Census enumeration universe,
and assigns the place participant’s record an A03. The county participant receives an R03 on
their C action and can Appeal the address record to reinstate it into the 2020 Census
enumeration universe.

A01 – Address is in the 2020 Census in the same block. The Census Bureau will include this address in
the 2020 Census for the participant’s jurisdiction in the same block, and accepts the LUCA update.
(Ineligible for Appeal.)


Participant adds an address (an A action) and the Census Bureau accepts it where the
participant says.



Participant updated a street name or geocode (a C action) and the Census Bureau agrees.

A02 – Address is in the 2020 Census in a different block. The Census Bureau will include this address in
the 2020 Census for the participant’s jurisdiction in a different block, and accepts the LUCA update.
(Ineligible for Appeal.)


Participant adds an address (an A action) and the Census Bureau accepts it in a different block.
This action would receive an A02.



Participant submits an address record as an add (an A action). The Census Bureau has the same
address in a different block within the participant’s jurisdiction. This action would receive an
A02.



Participant updated a street name or geocode (a C action) and the Census Bureau accepts it in a
different block. This action would receive an A02.

A03 – Address is not in the 2020 Census. The Census Bureau will exclude this address from the 2020
Census for the participant’s jurisdiction, and accepts the LUCA update. (Ineligible for Appeal.)
U.S. Census Bureau

2020 Census LUCA Feedback Respondent Guide



Participant submitted an address for deletion (a D action) because it no longer exists and the
Census Bureau agrees that the address no longer exists. The Census Bureau will exclude this
address from the 2020 Census. This action would receive an A03.



Participant submitted that the building was non-residential (an N action) and the Census
Bureau’s Master Address File (MAF) confirms the record is a commercial record. This action
would receive an A03.



Participant submitted the address as out of their jurisdiction (a J action), an adjacent jurisdiction
added the same record (an A action), and the Census Bureau agrees with the A action in the
adjacent jurisdiction. The J action would receive an A03. The A action would receive either A01
or A02.

R01 – Address is in the 2020 Census in the same block. The Census Bureau will include this address in
the 2020 Census for the participant’s jurisdiction in the same block, and rejects the LUCA update.
(Ineligible for Appeal.)


Participant submitted a group quarters address record with an apartment unit number (an A
action) and the Census Bureau rejects the new address record as invalid. The Census Bureau will
enumerate the group quarters at the main address in the same block submitted by the
participant.6 This action would receive an R01.7



Participant misused the C action to change a house number or a within structure ID (WSID), both
un-editable fields. The participant needed to submit these as add/delete combinations rather
than changing the house number or WSID. This action would receive an R01.



Participant submitted the address for deletion (a D action) and the record is a known, valid
residential address from the USPS Delivery Sequence File (DSF). This action would receive an
R01.



Participant submitted the address as non-residential (an N action) and the record is a known,
valid residential address from the USPS DSF. This action would receive an R01.



Participant submitted the address as out of jurisdiction (a J action) and the record is a known,
valid residential address in their jurisdiction from the USPS DSF. This action would receive an
R01.

R02 – Address is in the 2020 Census in a different block. The Census Bureau will include this address in
the 2020 Census for the participant’s jurisdiction in a different block, and rejects the LUCA update.
(Ineligible for Appeal.)


Participant submitted a geocode change (a C action) and the Census Bureau rejects the new
geocode keeping the address in the original location. This action would receive an R02.



Participant submitted a geocode change (a C action) and the Census Bureau chooses “third
block” (meaning the location is not where it was on the LUCA Review Phase materials, NOR
where the participant says, but the Census Bureau moved the record to a third block). This
action would receive an R02.



This example involves two or more jurisdictions. A state participant submitted a D action, but a
county participant submitted geocode change (a C action) on the same address. The Census
Bureau would reject the state’s D action and keep the address in the 2020 Census in a different

If the block differed, this record would receive the R02 feedback processing code.
During the LUCA Review Phase, the Census Bureau only requested the main address, group quarters name and facility name (if
applicable) of the group quarters records because the group quarters enumeration operations enumerate at the main unit, not each
individual unit within the group quarters. Records submitted with additional information, like apartment unit information, are invalid.

block, the one submitted by the county. The state’s action would receive an R02. The county’s
action would receive an A01.

2.3



Participant submitted the address as non-residential (an N action) and the record is valid nonresidential address in a different block. This action would receive an R02.



Participant submitted the address as out of jurisdiction (a J action) and the record is a valid
residential address in a different block within their jurisdiction. This action would receive an
R02.

Feedback Address Count List (D-2209)

The Census Bureau provides the Feedback Address Count List (D-2209) to participants to show the
change in residential address block tallies between the LUCA Review Phase and the LUCA Feedback
Phase. The list contains the LUCA Review Phase tallies of residential addresses (housing unit and group
quarters) that were on the participant’s Census Address List and the current number of residential
addresses (housing unit and group quarters) in the Census Address List for each census block within the
jurisdiction. It is important to realize that tally differences do not indicate lack of coverage. It could
indicate a change to geocoding between census blocks in your jurisdiction. The tally differences may also
be the result of work performed during other census operations. There is no direct link between change
in tallies on the Feedback Address Count List and Appeal eligibility for individual address records on the
Detailed Feedback Address List.
The printed Feedback Address Count List is on 8 ½ x 11 inch (letter size) paper with 24 rows per page,
divided into two sections for a total of 48 blocks per page. Each section includes seven columns of
information. The last page contains a “Total” row at the bottom that summarizes each of the four
“count” columns. The Census Bureau provides the Feedback Address Count List sorted based on the
State County Code, Census Tract, and Census Block columns. See Figure 3 for an example of this
material for a fictitious entity

Paper Maps, PDF maps, and Shapefiles

The Census Bureau provides paper maps and/or PDF maps, or shapefiles during the LUCA Feedback
Phase, according to the final format that the participant selected for the LUCA Review Phase.
Participants use the maps for geocoding reference and for review of any map updates submitted during
the LUCA Review Phase. Maps may include feature updates provided by the submitting entity, other
LUCA participants, and/or other updates found by the Census Bureau during other census operations.
Map legends for both the large format maps and the small format block maps closely resemble the
legends used during the LUCA Review Phase, with minor changes made to symbology to reflect Appealeligible address records and the two types of residential addresses (housing units and group quarters).
Blue circles or blue squares, that represent housing units or group quarters respectively, show the
Appeal-eligible records while gray symbols of the same style show records ineligible for Appeal. For
examples of a small format block map (e.g., PDF maps) with the updated map symbols, see Figure 5 and
Figure 6.
Refer to the 2020 Census Local Update of Census Addresses Operation (LUCA) Respondent Guide; Paper
Address List Format (D-2031) included with the original LUCA Review Phase materials for details on the
large format maps, small format block maps, shapefiles, and the block to map sheet relationship list.8
This guide does not repeat all of the map-related information in D-2031 since the feedback map
materials are reference material for geocoding purposes only. Locate a copy of the D-2031 on the LUCA
website at .
IMPORTANT: Participants may not submit map or shapefile updates during the LUCA Feedback Phase
due to 2020 Census operational scheduling.

Chapter 3, The LUCA Paper Maps and Chapter 5, TIGER Partnership Shapefiles provide detailed examples and information.

CHAPTER 3

HOW TO FILE AN APPEAL

This chapter provides information on the process to Appeal addresses while reviewing the 2020 Census
LUCA feedback materials. The Federal Register notice on the 2020 Census LUCA Appeals Process forms
the basis for much of the content in this chapter. A copy of the Federal Register notice is included in the
feedback materials package or can be located on LUCA website at .

3.1

Background

To ensure that tribal, state, and local governments participating in 2020 Census LUCA have a means to
Appeal the Census Bureau’s determinations, the Census Address List Improvement Act of 1994 requires
that the Administrator of OMB’s Office of Information and Regulatory Affairs (OIRA), acting through the
Chief Statistician and in consultation with the Census Bureau, develop an Appeals Process by
establishing a temporary federal entity, the 2020 Census LUCA Appeals Office. This office will resolve
any disagreements that may remain after participating governments receive the Census Bureau’s LUCA
Feedback materials and make a final decision on the inclusion of appealed addresses. Participants must
contact staff in the 2020 Census LUCA Appeals Office, not the Census Bureau, for specific Appeal-related
questions. Reach the Appeals Staff toll-free, by phone, at (888) 222-9907.

3.2

Deadline for Filing an Appeal

The deadline for filing an Appeal is 45 calendar days after the date the participant receives their
feedback materials from the Census Bureau. The 2020 Census LUCA Appeals Office defines “receipt” as
the delivery date reported to the Census Bureau by the delivery service carrier.
In order to safeguard the confidential address materials covered by Title 13, the submission of an Appeal
to the Appeals Staff must adhere to the Census Bureau's specific guidelines for handling materials
supplied with the feedback materials. The participant must submit its Appeal materials to the Appeals
Staff following the instructions outlined in Section 3.5, and should keep a record of the date it submits
these materials in case there are questions about the submission date. The participant may not submit
any materials to the Appeals Staff after the 45 calendar day period has elapsed.
Upon receipt of an Appeal, the Appeals Staff will send a confirmation of receipt to the participant. They
also will notify the Census Bureau that a participant has filed an Appeal.

3.3

Procedures for Filing an Appeal

A participant is eligible to file an Appeal if they returned address additions or corrections to the Census
Address List during the LUCA Review Phase, or if they certified, after review, that the Census Address
List was correct and required no updates. A participant may Appeal the following types of addresses:


Address deletions from the Census Address List by another level of government participating in
LUCA or by a different census operation that participants did not comment on during the LUCA
Review Phase. The Detailed Feedback Address List identifies these addresses with the X01
feedback processing code in column 5 (Feedback Code). The 2020 Census enumeration universe
excludes these records.

U.S. Census Bureau

2020 Census LUCA Feedback Respondent Guide



Address additions and corrections provided during the LUCA Review Phase that the Census
Bureau processed, but denied and excluded in the 2020 Census enumeration universe. The
Detailed Feedback Address List identifies these addresses with the R03 feedback processing
code in column 5 (Feedback Code).

IMPORTANT REMINDER:

Only the X01 and R03 address records are eligible for Appeal.

As mentioned in Section 2.2, to facilitate the participant’s feedback review, the Census Bureau provides
the Detailed Feedback Address List sorted based on the following order of the Feedback Code column:
X01, R03, A01, A02, A03, R01, and R02. Within each feedback processing code, the sort is by the LUCA
Review Phase sort order (i.e., tract/block or street name/house number). Performing this dual sort
promotes the Appeal-eligible records to the beginning while retaining the reference to the sort from the
LUCA Review Phase materials.
For each X01 and R03 coded address record on the Detailed Feedback Address List that the participant
believes should be reinstated in the Census Address List, insert a ”Y” in column 1 (Appeal Flag) for that
address.

3.4

Supporting Documentation

The 2020 Census LUCA Appeals Office requires eligible participants to provide evidence of existence and
the location for appealed addresses. To this end, eligible participants must provide the supporting
documentation for all appealed addresses as specified below.
For the 2020 Census LUCA Appeals process, participants may apply the same set of supporting evidence
to a group of addresses. For example, participants may wish to supply one set of supporting evidence for
related addresses such as those associated with a single housing development or complex if the set of
supporting evidence substantiates the existence of the full set of linked addresses. In other cases, a
written description of a robust process to review and verify the Appeal-eligible addresses using highly
accurate sources may support a set of addresses. Participants must supplement this narrative with a
selection of appealed addresses associated with an exact location and proven with one of the evidence
types listed below.
Eligible governments must submit the following supporting documentation with their Appeal:


A written narrative with an explanation of the eligible government’s position for why the
Appeals Staff should adopt their recommendation.



A detailed description of the address source(s) that helps to verify the existence of an address or
group of addresses. Eligible governments may incorporate the detailed description(s) into the
written narrative or may supply separate address source documentation. For each address
source used to support the existing of address(s), the description should include the following:
o Date of the address source.
o Frequency of update of the address source (e.g., daily, monthly, quarterly, yearly, etc.).
o Methods used to update the address source.
o Quality assurance procedure(s) used in maintaining the address source.
o How the eligible government and/or originator of the source uses the information.

U.S. Census Bureau

2020 Census LUCA Feedback Respondent Guide



Evidence to support the existence of the appealed address. Participants must link the evidence
directly to a particular appealed address or particular set of appealed addresses. Useful types of
supporting evidence include:
o Documentation of on-site inspection and/or interview of residents and/or neighbors.
o Issuance of recent occupancy permit(s) for unit(s). Building permits are not acceptable, as
they do not ensure completed construction of the units.
o Provision of utilities (electricity, gas, sewer, water, telephone, etc.) to the residence. The
utility record must show that this is not a service to a commercial unit, or an additional
service to an existing residence (such as a second telephone line).
o Provision of other governmental services (housing assistance, welfare, etc.) to residents of
the unit(s).
o Photography, including aerial photography or satellite imagery.
o Land use maps.
o Local 911 emergency lists, if they distinguish residential from commercial units.
o Tax assessment records, if they distinguish residential from commercial units.

For each address on the Detailed Feedback Address List that the participant is appealing, write (or key if
the supporting documentation is in digital format) the Appeal Flag from column 1 and the line number
from column 2 (Line #) on the supporting documentation to show the exact location in the document
where the evidence for that address is located. For example, if submitting property tax records that
contain 30 tax records per page, print (or key) the Appeal Flag and Line # (e.g., “Y4” if the Appeal-eligible
record was line number 4 of the Detailed Feedback Address List) on the one tax record among those 30
tax records that supports the Appeal.
Only submit documentation specific to the addresses being appealed, e.g., one property tax record or
one utility record for each appealed address or only those pages of a list with the records for the
appealed addresses appropriately marked. If a supporting document validates the existence of multiple
appealed records, participants must develop a method for linking the supporting evidence to the
appealed address or group of appealed addresses. Whatever method a participant chooses to associate
source material with their appealed records, it is crucial for the Appeals Staff to be able to determine
which evidence supports which address records or set of address records in order to process the Appeal.
Direct questions on the Appeals process to the 2020 Census LUCA Appeals Office toll-free, by phone, at
(888) 222-9907. The LUCA website, , also lists their contact information.

3.5

Preparing and Submitting Appeal Materials to the 2020 Census LUCA
Appeals Office

To file an Appeal, participants must submit a hard copy of their written narrative and of their pages of
the Detailed Feedback Address List with records flagged for Appeal as described below in Section 3.5.1.
They may choose to include hard copies of their source description(s) and supporting documentation or
they may choose to include a CD or DVD with digital copies of their supporting documentation and
source description(s) to accompany their hard copy Detailed Feedback Address List pages and written
narrative.

U.S. Census Bureau

2020 Census LUCA Feedback Respondent Guide

3.5.1

Preparing Appeal Materials for Submission

After completing the review of the LUCA Feedback Phase materials and flagging some records for
Appeal, return only the pages of the Detailed Feedback Address List that contain records with a “Y” in
the Appeal Flag column. Please do not return unedited pages to the 2020 Census LUCA Appeals Office;
doing so complicates their review. Make, and retain, a copy of the edited pages for reference while the
Appeals Staff conducts their work. Once the Appeals process completes, participants must destroy or
return these materials to the Census Bureau as part of the Closeout Phase discussed in Chapter 4.
Prepare a written narrative with the explanation of the participant’s Appeal to the 2020 Census LUCA
Appeals Office. The narrative should outline the basis of the Appeal and the participant’s position for
why the 2020 Census LUCA Appeals Office should adopt the recommendations. The narrative should
provide the contact information for the Appeal, including:


The name of the governmental jurisdiction filing the Appeal.



The name, mailing address, telephone number, and email address (if any) for the jurisdiction’s
contact person for the Appeal. Ensure this person is on the D-2005 – Confidentiality Agreement
Form.



An inventory of the supporting documentation pages/materials enclosed (e.g., submitting four
pages of supporting documentation for 15 appealed records or submitting three documents that
denote support for 15 appealed records). Consider including a brief summary of how to navigate
the documentation in conjunction with the Detailed Feedback Address List.

The detailed description(s) of the address source(s) can be included within the written narrative or
within separate documentation. If participants use more than one source, they must be sure to detail
the differences between the sources and identify how they used the sources during the Appeals process.
Organize the supporting documentation. Retain a copy (digital and/or hard copy) of the supporting
documentation to retain for reference in case the Appeals Staff have questions about the submitted
materials.

3.5.2

Shipping Instructions for Submitting Appeal Materials

Participants ship their hard copy materials and their CD or DVD of their digital information, if applicable,
using the following instructions to package and ship materials to the 2020 Census LUCA Appeals Office:


Double wrap the Appeals material (hard copy materials and/or the CD/DVD) using an inner and
an outer envelope (or container), one within the other. These should be durable enough to
prevent someone from viewing or tampering with the enclosed material.



Label both sides of the inner envelope (or container) with the notice:



“DISCLOSURE PROHIBITED BY TITLE 13, U.S.C.”



Place the inner envelope (or container) into the outer envelope.



Do not label the outer envelope with the disclosure notice.



Ship using a service that provides tracking information, such as United States Postal Service
(USPS) trackable delivery, FedEx, United Parcel Service (UPS), or similar service. Retain the
tracking number as proof of delivery.

CHAPTER 4

2020 CENSUS LUCA CLOSEOUT

The Census Bureau must account for all Title 13 material delivered to participants during both the LUCA
Review Phase and Feedback Phase, and any copies of those materials, to close out the operation for
2020. It is the responsibility of the LUCA liaison to ensure the proper disposal of the Title 13 material.
The designated liaison is required to verify the destruction or return of any remaining Title 13 materials,
both paper and digital (i.e., paper copies, backup files, etc.) by signing and returning to the Census
Bureau the D-2012 – Destruction or Return of Title 13, U.S.C. Materials Form enclosed with the feedback
materials and found in Appendix C. The destruction of materials is the preferred method rather than
returning the materials to the Census Bureau.
IMPORTANT: Please await a response from the 2020 Census LUCA Appeals Office on the status of the
Appeal prior to destroying or returning the Title 13 material.
All LUCA reviewers and anyone with access to Title 13 materials (includes all persons who signed the D2005 – Confidentiality Agreement Form) are required to sign and date the D-2012 form once the LUCA
Appeals process concludes. Should any liaison, reviewer, or anyone with access to Title 13 materials
leave before the completion of the LUCA operation, they are required to sign out of the program by
signing and dating this form. If any liaison or reviewer leaves and fails to sign and date this form, the
current liaison can sign out on their behalf.
Participants choosing to destroy their materials must return the D-2012 as soon as possible after the
destruction of materials and must ensure the form contains all appropriate liaison and reviewer
signatures to close out 2020 Census LUCA. Use the enclosed, postage-paid envelope to return the
D-2012. Participants choosing to return their materials, rather than destroy them, must include this
form with the materials and must follow the packaging and shipping instructions in Appendix A to
ensure the security of the Title 13 materials.

APPENDIX A CONFIDENTIALITY AND SECURITY GUIDELINES
A1

Introduction

Federal law, under Title 13 of the United States Code (U.S.C.), requires the U.S. Census Bureau to
maintain the confidentiality of the information it collects. The Census Bureau takes this responsibility
very seriously. Respondents place their trust in the Census Bureau each time they complete a survey or
an interview. This trust in confidentiality is critical to the success of the Census Bureau’s mission to
collect and report the most accurate data possible. To uphold the law, the Census Bureau requires that
any individuals with access to Title 13 materials adhere to the prescribed confidentiality and security
guidelines.

Title 13, U.S. Code

Chapter 1, Section 9 of Title 13, U.S. Code states: “Neither the Secretary, nor any other officer or
employee of the Department of Commerce or bureau or agency thereof, or local government census
liaison, may, except as provided in section 8 or 16 or chapter 10 of this title:
1) Use the information furnished under the provisions of this title for any purpose other than the
statistical purposes for which it is supplied; or
2) Make any publication whereby the data furnished by any particular establishment or individual
under this title can be identified; or
3) Permit anyone other than the sworn officers and employees of the Department or bureau or
agency thereof to examine the individual reports.”
In 1994, under Public Law 103-430, the U.S. Congress amended Chapter 1 of Title 13 to allow the local
government census liaison to review and update the Census Bureau’s address information for their
jurisdiction. Although the amendment allows official local government access, the amendment
reaffirmed the confidential nature of the Census Bureau’s address information. Census information
protected under Title 13 includes:


Everything on a completed or partially completed questionnaire or any information obtained in
a personal or telephone interview.



Individual addresses maintained by the Census Bureau, including those shared with
governments through the 2020 Census Local Update of Census Addresses Operation (LUCA).



Digital or paper maps with latitude/longitude coordinate data that identify the location of living
quarters (structure points).



The penalty for the wrongful disclosure or release of information protected by Title 13 is a fine
of not more than $250,000 or imprisonment for not more than 5 years, or both, as set by
Section 214 of the Code and the Uniform Sentencing Act of 1984.

Title 13 U.S.C. does not apply to generalized address information, such as address range data available in
the Census Bureau’s digital products or address counts by census block.

The Confidentiality Agreement

To participate in LUCA, a government must designate a LUCA liaison. The LUCA liaison, LUCA reviewers,
and anyone with access to Title 13 materials must sign the Confidentiality Agreement. The Census
Bureau will not deliver LUCA materials to a participant until we have received the completed and signed
Confidentiality Agreement and the Confidentiality and Security Checklist.
U.S. Census Bureau

2020 Census LUCA Feedback Respondent Guide

A-1

The Census Bureau’s Title 13 data, including addresses and latitude/longitude coordinate data (structure
points), cannot be used to create, update, nor modify a tribal, state, or local jurisdiction’s address list or
database.
A signature on the Confidentiality Agreement constitutes a legal agreement by each individual to keep
confidential Census Bureau Title 13 data and abide by the security guidelines outlined below. While
access to Title 13 materials is temporary, the commitment to keep the information confidential is
effective for a lifetime.

Security Guidelines

The LUCA liaison accepts the responsibility for protecting and safeguarding the LUCA materials. The
liaison must restrict access to the Census Bureau’s information covered under Title 13 to those
individuals who have signed the Confidentiality Agreement.

A4.1 Protecting Digital Title 13 Materials
Operating systems, programs, applications, and data are collectively referred to as Information
Technology (IT) systems in this document. Any IT systems used for LUCA participation must be accessible
only to those who have signed the Confidentiality Agreement. Your IT systems should restrict the read,
write, and delete functions to all Title 13 materials.
Digital Guidelines


Construct electronic security profiles to allow only the LUCA liaison and the LUCA reviewers to
access Title 13 materials. Test your security to ensure that access is restricted.



Use file encryption and passwords to protect all digital Title 13 materials at all times. Encrypt
files using the Advanced Encryption Standard (AES) with key length of 256 bits.



Do not leave computers with Title 13 materials unattended. Log-off computers, lock terminals,
and lock the room when not in use.



Label all digital media and every printed page of any paper materials produced from Title 13
digital media with the following:
“This document contains information, the release of which is prohibited by Title 13, U.S.C.,
and is for U.S. Census Bureau official use only. Wrongful disclosure or release of information
can be punished by fine or imprisonment (Public Law 99-474).”



Do not send backup digital media off-site. Store in a secured area. Do not mix, store, or back-up
LUCA data with other data.



Clear dedicated digital media containing Title 13 materials before reuse. Overwrite Title 13
digital data minimally three times using a commercial disk utility program.



Do not disclose precise or even anecdotal information about Census Bureau addresses or
locations to anyone who has not signed the Confidentiality Agreement.

A4.5 Destruction of Census Bureau Confidential Materials
After the entire LUCA operation has concluded, all Title 13 materials must be destroyed (preferred
method) or returned according to the Census Bureau’s specific guidelines. The LUCA liaison is required
to verify the destruction or return of any Title 13 materials, both paper and digital, including all paper
copies, backup files, etc., by signing and returning the Destruction or Return of Title 13, U.S.C. Materials
Form. In addition, anyone who signed the Confidentiality Agreement is required to sign this form once
his or her participation in LUCA has ended. Should any liaison, reviewer, or anyone who signed the
Confidentiality Agreement leave before the completion of LUCA, they must sign and date this form. If
any liaison, reviewer, or anyone who signed the Confidentiality Agreement is unable to sign and date the
form, the current liaison must sign and date on their behalf.
Only individuals who signed the Confidentiality Agreement are permitted to destroy Title 13 materials:


Never deposit Title 13 materials in a trash or recycle container, or dispose of information in a
landfill before destruction procedures are completed.



Destruction must prevent recognition or reconstruction of paper or digital Title 13 materials.
Use one of the following methods:
o Shredding or pulping.
o Chemical decomposition.
o Pulverizing (such as, hammer mills, choppers, etc.).
o Burning (facility approved by the Environmental Protection Agency).
o Clear dedicated digital media containing Title 13 materials before reuse. Overwrite Title 13
digital data minimally three times using a commercial disk utility program.
o Clearing or sanitizing all print servers and multi-function printing or scanning devices with
stored images or print files containing Title 13 data.
o Destroying CDs and DVDs using a shredder or other method suitable for rendering them unusable.

Note: Hand tearing is an unacceptable method of Title 13 material disposal before destruction.

APPENDIX D GLOSSARY
Address Count List—This material was included as part of the LUCA Review Phase materials. It identified
the number of housing unit addresses and group quarters addresses on the Census Address List for each
census block within a jurisdiction.
Address range—The lowest and highest address numbers used to identify structures along each side of
a street segment that has city style addresses. Usually one side of the street has even address numbers
and the other side has odd address numbers.
Block to Map Sheet Relationship List—This material was included as part of the LUCA Review Phase
materials. It identified census block numbers and the Census Bureau large format map(s) on which each
block is located.
Boundary—A line, on a map, either invisible or coincident with a visible feature that identifies the
extent of a geographic entity, such as a census tract, city, county, or state. A boundary marks the limits
of an area.
Census Address List—This material was included as part of the LUCA Review Phase materials. The
Census Address List, extracted from the Master Address File (MAF) for review and update during 2020
Census LUCA, contains all the residential addresses (city style and non-city style) known to the Census
Bureau for your government. It also contains census geographic codes (state, county, census tract,
census block) that indicate the location of each address. Many addresses also contain latitude and
longitude coordinates depicting the address location.
Census block—A census block is an area bounded by visible and/or invisible features shown on Census
Bureau maps. A census block is the smallest geographic area created by the Census Bureau for which it
collects and tabulates decennial census data. Census blocks are numbered within census tracts and are
uniquely numbered within census tracts.
Census block number—Census block numbers are a four-digit number. Census blocks are numbered
uniquely within each census tract.
Census Bureau—An agency within the U.S. Department of Commerce. The U.S. Census Bureau is the
country's preeminent statistical collection and dissemination agency. It publishes a wide variety of
statistical data about people and the economy of the nation. The Census Bureau conducts
approximately 200 annual surveys and conducts the decennial census of the United States population.
Census Bureau map—Any map produced by the Census Bureau. A Census Bureau map displays
geographic entities used in a Census Bureau sponsored census or survey for which the Census Bureau
tabulates data.
Census tract—A small, relatively permanent statistical subdivision of a county or statistically equivalent
entity delineated for data presentation. Designed to be relatively homogeneous units with respect to
population characteristics, economic status, and living conditions at the time of establishment, census
tracts generally contain between 1,000 and 8,000 people, with an optimum size of 4,000 people.
Delineated with the intention of being stable over many decades, census tract boundaries generally
follow relatively permanent visible features. However, they may follow governmental unit boundaries
and other invisible features in some instances; the boundary of a state or county (or statistically
equivalent entity) is always a census tract boundary.
U.S. Census Bureau

2020 Census LUCA Feedback Respondent Guide

D-1

Census tract number—Unique numbers to identify census tracts within a county or statistically
equivalent entity. Census tract numbers are a four-digit number followed by a decimal point and a twodigit number for suffixed tracts, e.g., 1234.01. For census tracts without a suffix, the number will contain
a period with zero fill, e.g., 4567.00. Leading zeros for census tracts, e.g., 0001.00, are not shown on
Census Bureau maps. This tract would appear as “1” on the paper maps.
City style address—The Census Bureau’s definition of a city style address is an address consisting of a
house number and street or road name. For example, 201 Main Street is a city style address. The
address may or may not be used for the delivery of mail and may include apartment
numbers/designations or similar identifiers.
Confidentiality—The guarantee made by law (Title 13, United States Code) to individuals who provide
information about themselves or their business to the Census Bureau. This item refers to the Census
Bureau’s promise of nondisclosure of that information to others.
County—The primary legal division of most states. Most are governmental units with powers defined by
state law.
Detailed Feedback Address List— A hard copy address list generated by the Census Bureau that shows
all accepted (i.e., properly formatted) address record updates submitted by the participant during the
LUCA Review Phase and a feedback processing code identifying a specific action taken by the Census
Bureau on that address record. This address list also identifies any address records not commented on
and deleted from the original Census Address List by a different census operation or another level of
government participating in LUCA.
Edges—All linear features contained in the MAF/TIGER database.
Edges shapefile— An Esri® shapefile of the linear features contained in the MAF/TIGER database During
the LUCA Review Phase, participants using digital map materials used the edges shapefile to add, delete,
or change linear feature attributes. During the LUCA Feedback Phase, participants use the edges
shapefile for reference only to review updates they made during the LUCA Review Phase or other
updates made since the LUCA Review Phase concluded.
Enumeration at Transitory Locations (ETL) operation—Provides coverage for locations where people
live in non-traditional housing that is transient or movable in nature. Most census questionnaires are
mailed, or hand-delivered by census personnel, to known addresses in the Census Master Address File
(MAF). However, due to changes in society, some people no longer maintain a traditional residence
(house, apartment, condo, etc.), and have decided to live in boats, motorized recreational vehicles (RVs),
trailers that are pulled by car or trucks, or any other type of housing that is movable or mobile, including
tents. For operational purposes, we refer to these as “portable housing units.”
The type of Transitory Locations (TLs) that are included in the ETL are:


Recreational (RV) parks.



Marinas.



Campgrounds.

Federal Information Processing Series (FIPS)—These are codes formerly known as Federal Information
Processing Standards codes, until the National Institute of Standards and Technology (NIST) announced
its decision in 2005 to remove geographic entity codes from its oversight. The Census Bureau continues
to maintain and issue codes for geographic entities covered under FIPS oversight, albeit with a revised
meaning for the FIPS acronym. Geographic entities covered under FIPS include states, counties,
congressional districts, core based statistical areas, places, county subdivisions, sub-minor civil divisions,
consolidated cities, and all types of American Indian, Alaska Native, and Native Hawaiian areas. FIPS
codes are assigned alphabetically according to the name of the geographic entity and may change to
maintain alphabetic sort when new entities are created or names change. FIPS codes for specific
geographic entity types are usually unique within the next highest level of geographic entity with which
a nesting relationship exists. For example, FIPS state, congressional district, and core based statistical
area codes are unique within nation; FIPS county, place, county subdivision, and sub-minor civil division
codes are unique within state. The codes for American Indian, Alaska Native, and Native Hawaiian areas
also are unique within state; those areas in multiple states will have different codes for each state.
Feedback Address Count List— A hard copy address count list or comma-delimited text file, in .csv
format, containing the number of housing unit and group quarters residential addresses on the LUCA
Review Phase Census Address List and the current number of housing units and group quarters
residential addresses for each census block within the participant’s jurisdiction. This product
accompanies the Feedback Phase materials.
Feedback Block to Map Sheet Relationship List—This material is included as part of the Feedback Phase
materials. It identifies census block numbers and the Census Bureau large format map(s) on which each
block is located.
Geocodes—Codes that place an individual address in its correct geographic location, which, in census
terms, includes the correct state, county, census tract, and census block codes. Because the Census
Bureau counts people where they live, geocodes provide information to Census enumerators for
locating an address. Accurate geocoding also ensures the Census Bureau counts housing units, and the
people associated with them, in the correct census geography.
Geographic Information System (GIS)—A computer system for the storage, retrieval, and maintenance
of information about the points, lines, and areas that represent the streets and roads, rivers, railroads,
geographic entities, and other features on the surface of the Earth-information that previously was
available only on paper maps.
Geographic Update Partnership Software (GUPS)—A self-contained GIS update and processing package
provided by the Census Bureau for participation in a variety of Census geography programs, including
2020 Census LUCA. Pre-packaged to include all of the components for 2020 Census LUCA, the GUPS
contains the Detailed Feedback Address List, Feedback Address Count List, and TIGER Partnership
shapefiles for the LUCA Feedback Phase. It contained the Census Address List, address count list, and
TIGER Partnership shapefiles for use during the LUCA Review Phase. GUPS allows the participant to add
external geospatial data (shapefiles, geodatabases, and imagery) for comparison and update purposes.
Delivery of all data (software, address list, address count list and shapefiles) is on DVD.
Governmental unit (GU)—A geographic entity established by legal action for the purpose of
implementing specified governmental functions. Most governmental units provide a number of general
government services and raise revenues (usually through taxing authority).

U.S. Census Bureau

Group quarters (GQ)—A place where people live or stay normally owned or managed by an entity or
organization providing housing and/or services for the residents. These services may include custodial or
medical care as well as other types of assistance, and residency is commonly restricted to those
receiving these services. People that live in a group quarters are usually not related. Group quarters
include such places as college residence halls, residential treatment centers, skilled nursing facilities,
group homes, military barracks, correctional facilities, workers’ dormitories, and facilities for people
experiencing homelessness.
Highest elected official (HEO)—The person most responsible for the governmental activities of a local
government. This person receives the LUCA invitation letter, and must designate a LUCA liaison, to

Housing unit (HU)—A single-family house, townhouse, mobile home, trailer, apartment, group of
rooms, or a single room occupied as a separate living quarters or, if vacant, intended for occupancy as a
separate living quarters. A separate living quarters is one in which one or more occupants (or intended
occupants, if vacant) live separate from any other individual(s) in the building and have direct access to
the living quarters without going through another living quarters, such as from outside the building or
through a common hall.
Living quarters—Any site where people live, stay, or could live. Living quarters are classified as housing
units or group quarters. They are usually found in structures intended for residential use, but also may
be found in structures intended for non-residential use as well as tents, vans, shelters for people
without housing, dormitories, barracks, and so forth, or they might not be associated with a structure at
all.
LUCA liaison—The main point of contact appointed by the highest elected official (HEO) of each
jurisdiction to review the Census Address List and maps against local records to identify differences. This
person, also known as the program primary liaison or designated liaison, accepts responsibility for
safeguarding Title 13 materials and are ultimately responsible for destroying (or returning) the
materials. They must sign out of LUCA and submit the Destruction or Return of Title 13 Materials Form
(D-2012) after ensuring all LUCA reviewers sign the form as well.
LUCA reviewer—Individual(s) selected by the HEO or LUCA liaison to assist with conducting the LUCA
review. They accept responsibility for safeguarding Title 13 materials and, like the liaison, must sign out
of LUCA and submit the Destruction or Return of Title 13 Materials Form (D-2012).
Master Address File (MAF)—The Census Bureau’s nationwide database of all addresses and
physical/location descriptions known to the Census Bureau used to support many of the Census
Bureau’s operations. Besides containing mailing addresses and ZIP Codes, a MAF record also contains
geographic information about the location of addresses. The Census Bureau’s Geography Division
regularly updates the MAF/TIGER database from various sources, including the United States Postal
Service (USPS) Delivery Sequence File (DSF) and other sources of updates such as current surveys and
locally provided sources.
MAF/TIGER Database (MTDB)—The Census Bureau’s nationwide geographic database, which integrates
the Master Address File (MAF) and Topologically Integrated Geographic Encoding and Referencing
(TIGER) files.
Metadata—Describes the data content, coordinate system/projection, author, source, and other
characteristics of GIS files.

Minor civil division (MCD)—The primary governmental or administrative division of a county in 29
states and the Island Areas having legal boundaries, names, and descriptions. The MCDs represent many
different types of legal entities with a wide variety of characteristics, powers, and functions depending
on the state and type of MCD. In some states, some or all of the incorporated places also constitute
MCDs. MCDs are identified by a variety of terms, such as town (in eight states), township, and/or
district. They include both functioning and nonfunctioning government entities.
Non-city style address—An address that does not have a house number and/or street name or may not
include a complete house number and street name address. This includes rural route and box number
address and highway contract route addresses, etc., which may include a box number, post office boxes
and drawers, and general delivery.
Occupied housing unit—A housing unit is classified as occupied if it is the usual place of residence of the
individual or group of persons living in it at the time of enumeration or if the occupants are only
temporarily absent; for example, away on vacation. Occupied rooms or suites of rooms in hotels,
motels, and similar places are classified as housing units only when occupied by permanent residents,
that is, individuals for whom the facility is their usual place of residence.
Place—A concentration of population either legally bound as an incorporated place, consolidated city,
or identified by the Census Bureau as a census designated place.
Regional Census Center (RCC)—Temporary offices set up approximately two years prior to the decennial
census. The geographic staff from the Regional Offices are assigned to their respective RCC and assist
with the execution of various geographic operations as well as provide support for the field operations
conducted during the decennial.
Regional Office (RO)—One of six permanent Census Bureau offices distributed across the nation.
Regional offices are responsible for the Census Bureau’s field operations.
Shapefile—Digital representations of geographic features, such as roads and boundaries used to create
maps. A shapefile stores non-topological geometry and attribute information for the spatial features in a
dataset. The Census Bureau provides county-based shapefiles in Esri shapefile format.
Street segment—The portion of a street or road between two features that intersect that street or road,
such as other streets or roads, railroad tracks, streams, and governmental unit boundaries. The Census
Bureau records the known address ranges for every street segment with city style addresses.
Structure Point (map spot)—A dot on a Census Bureau map, used to show the location of one or more
living quarters. A maximum of four digits plus one alpha character is assigned within a census block to
each structure point. Structure points are stored in the TIGER database and are protected by Title 13
U.S.C.
Topologically Integrated Geographic Encoding and Referencing (TIGER)—The Census Bureau’s digital
map, including the geographic coordinates and names of streets, water features, other linear features,
and boundaries for all jurisdictions and statistical areas that provide the geospatial framework for
collecting and tabulating census data. TIGER also contains the structure coordinates of address records
in the Master Address File (MAF) and address ranges along street features used for geocoding MAF
records to census geography.

Transitory locations (TL)—Movable or mobile housing, or portable housing units, including boats,
motorized recreational vehicles (RVs), tents, trailers that are pulled by cars or trucks, or any other type
of portable housing.
Vacant housing unit—A habitable structure containing living quarters that is not occupied. New housing
units not yet occupied are classified as vacant housing units if construction has reached a point where
exterior windows and doors are installed and final usable floors and a roof are in place. Vacant units are
excluded if they are open to the elements, or if there is positive evidence, such as a sign on the house,
that the housing unit is to be demolished or has been condemned.

BACKGROUND
A.

General Information

The 2020 Census Local Update of Census Addresses Operation (LUCA) is a voluntary decennial
census operation. LUCA is the only opportunity prior to the 2020 Census for tribal, state, and
local governments (including the District of Columbia and Puerto Rico) to review and update
the Census Bureau’s residential address list for their jurisdiction. The Census Bureau relies on a
complete and accurate address list to reach every living quarters and associated population for
inclusion in the census. The Census Address List Improvement Act of 1994 (Public Law 103-430)
authorizes the LUCA operation. Refer to for more information.
In accordance with the law, the LUCA Feedback Phase provides participating governments with
detailed feedback materials that document which local address updates the Census Bureau
processed. LUCA participants may dispute the processing results of certain addresses, only if
those addresses meet certain eligibility criteria. Participants must file their Appeal within 45
calendar days after the receipt of the feedback materials. Appeals filed after the deadline will
be denied. Filing an Appeal is optional and is not a requirement of LUCA.
IMPORTANT:

The final Federal Register notice is included with the feedback materials and is available
on the LUCA website, , for participants to consult before beginning their review.

Census Bureau Processing of LUCA submissions

The Census Bureau reviewed all addresses submitted by LUCA participants during the LUCA
Review Phase and processed those meeting the defined criteria. In addition, the Census Bureau
made necessary corrections and updates to the census maps from the LUCA Review Phase
submissions.

Confidentiality and Security

All of the requirements and guidelines for protecting the Census Bureau’s confidential Title 13,
United States Code (U.S.C.) materials followed for the LUCA Review Phase are applicable to the
LUCA feedback materials.1 All participants are required to sign a Confidentiality Agreement
Form in accordance with Title 13, U.S.C. to maintain the confidentiality of the census address
information they received from the Census Bureau for review. Participants are required to have
the means to secure the Census Address List containing Title 13 information.
Persons who signed the D-2005 – Confidentiality Agreement Form for the LUCA Review Phase,
are not required to sign the form again. However, anyone who will review or have access to the
confidential Title 13 feedback materials and has not already signed form D-2005 must read and
agree to abide by the Confidentiality and Security Guidelines, included as Appendix A, and must
Title 13, U.S.C provides for the confidential treatment of census-related information, including individual addresses and map spots. Title
13 requires that all liaisons, reviewers, and anyone with access to Title 13 materials abide by the Confidentiality and Security Guidelines.
Title 13 also requires that the Census Bureau maintain the confidentiality for all of the information that it collects.

sign the Confidentiality Agreement Form before reviewing the materials. A blank D-2005 –
Confidentiality Agreement Form is included in this respondent guide as Appendix B. This form is
also available on the LUCA website at .
The D-2202 – Detailed Feedback Address List is Title 13 protected material. It is included, in
printed form only, in the feedback materials for all participants whose final format during the
LUCA Review Phase was the Paper Address List. In addition, if a participant’s final format for
maps was PDF maps, the Title 13 protected, small format block maps are on the enclosed DVD.
The PDF maps require a password to decrypt and open. The case-sensitive password, necessary
to open the small format block maps, is different from the password used during the Review
Phase. It arrives separately and prior to receiving the feedback materials. Keep the password
letter (D-2280) secure.
Following the LUCA Feedback Phase or a possible Appeal, at the conclusion of the 2020 LUCA
operation, the LUCA liaison must verify the destruction (preferred) or return to the Census
Bureau all Title 13 materials and copies by signing and returning the D-2012 – Destruction or
Return of Title 13, U.S.C. Materials Form. A blank form is included as Appendix C. This form is
also available online at the LUCA website. Additional information or assistance is available, tollfree, by phone at (844) 344-0169 or by email at [email protected].

Entity Identification Codes

All local government entity codes, also known as the “EntityID,” appearing in the feedback
materials have a two-letter code identifying the type of entity. County, place, and minor civil
division codes include the state two-digit Federal Information Processing Series (FIPS) numeric
code. Minor civil divisions also include the county three-digit FIPS numeric code. See Table 1 for
information regarding the entity identification codes.

CHAPTER 1. 2020 CENSUS LUCA FEEDBACK AND APPEALS
INTRODUCTION
This chapter provides introductory information on the materials paper address participants
receive as part of the LUCA Feedback Phase based on the final format of the LUCA Review
Phase.
IMPORTANT:

For participants needing visuals and detailed examples, the 2020 Census Local Update
of Census Addresses Operation (LUCA) Respondent Guide; Paper Address List Format (D2031) distributed during the LUCA Review Phase includes additional graphics and
information. Locate the respondent guide on the LUCA website,
, and
use it to supplement instructions in this material.

1.1 Feedback Materials
The Census Bureau provides LUCA Feedback Phase materials to eligible governments beginning
in July 2019 and ending in September 2019. Unless a participant declined feedback, the Census
Bureau provides LUCA feedback materials for jurisdictions that submitted address updates after
reviewing and applying each properly formatted address update to the Census Address List and
adding any new addresses not already included. The Census Bureau verified the participant
suggested address updates (additions, corrections, deletions, etc.) to ensure that all address
updates and additions exist and that they are in the correct census block. Participants that
reviewed the Census Address List, agreed with its contents during the LUCA Review Phase, and
asked to receive feedback also receive LUCA Feedback Phase materials.
The Census Bureau provides feedback materials according to the final format that the
participant selected for the LUCA Review Phase. For paper address list participants, there are
three product preferences described in the detailed sub-sections below. Regardless of the
product preference, the feedback materials include:2
•

1.2.4 Converting Comma Delimited Text Files
The Feedback Address Count List .csv file described above is a comma-delimited text file
provided to participants receiving a DVD (i.e., those receiving small format block maps or digital
maps). Many paper address participants may only need the printed version, but for those that
misplace their printed copy or need an additional copy, they may use this digital version to print
another copy or to sort and filter the digital version. The Feedback Address Count List is not
Title 13 material.
Most commercial spreadsheet and database programs can open the .csv files (e.g., Microsoft
Excel®, Microsoft Access®, etc.).4 However, in order to read the file contents properly,
participants must import the file rather than opening it. The following set of bullets use Excel
2016 to describe the proper way to open the .csv files.5

CHAPTER 2. REVIEWING THE 2020 CENSUS LUCA FEEDBACK
MATERIALS AND PROCESSING CODES
This chapter provides detail on the content within the feedback materials and lays the
foundation for conducting a review of the materials. It devotes a section to describing the
detailed feedback processing codes and identifying which records are eligible for Appeal based
on their feedback processing code.

2.1 Feedback Address Update Summary Report (D-2201)
The Census Bureau provides a printed copy of the Feedback Address Update Summary Report
(D-2201) to participants with their feedback materials package. Participants receiving small
format block maps or digital maps will also find a portable document format (PDF) file of this
report on their enclosed DVD. The report summarizes the Census Bureau processing performed
on the address records submitted by participants during the LUCA Review Phase. This report
displays the tallies of actions taken by the Census Bureau for all of the address updates that the
participant submitted and the total number of address records on the original Census address
list that were deleted by a different census operation or another level of government
participating in LUCA. See Figure 1 for an example of the report.
Section “A” of the summary report contains the total number of address records submitted to
the Census Bureau for the LUCA Review Phase, the total number of address records submitted
that were processed, and the total number of address records submitted without required
information and were not processed. Unprocessed addresses include those with blank or
invalid action codes, addresses submitted without geographic information such as the census
tract and block numbers or the latitude and longitude coordinates, or non-city style addresses
without a map spot or latitude and longitude coordinates. The total number of participant
address records submitted for processing (e.g., 100) equals the total number of address records
processed (e.g., 91) and the total number of address records not processed (e.g., 9).
IMPORTANT:

The total number of submitted address records processed by the Census Bureau (e.g.,
91 records in the case of Figure 2) equates to the number of records that appear in the
Detailed Feedback Address List.

Section “B” of the report displays the tallies of actions taken by the Census Bureau for all the
processed address records submitted with valid action codes and map spot/coordinates (or
geocodes). The total number of address records accepted as requested (e.g., 61) and the total
number of address records not accepted as requested (e.g., 30), equals the total number of
address records submitted and processed (e.g., 91) as shown in Section “A” of the report.
Section “C” of the report contains address records not commented on, but deleted from the
original Census Address List by a different census operation or another level of government
participating in LUCA. Review Section 2.2.3 for information on these deleted records.

2.2 Detailed Feedback Address List (D-2202)
The Census Bureau provides the Detailed Feedback Address List (D-2202) to participants as part
of their feedback materials in order to see the disposition of each submitted address record
U.S. Census Bureau

2020 Census LUCA Feedback Paper Respondent Guide

processed by the Census Bureau. Participants use the Detailed Feedback Address List to
determine which address records are eligible for Appeal and denote them accordingly. This
material shows all usable address record updates submitted by the participant, processed by
the Census Bureau, and a feedback processing code identifying a specific action taken on that
address record. In addition, the list contains any addresses that were on the participant’s
Census Address List during the LUCA Review Phase, but subsequently deleted by a different
census operation or another level of government participating in LUCA.
The printed Detailed Feedback Address List is on 8 ½ x 14 inch (legal size) paper, with six
addresses per page. To facilitate the participant’s feedback review, the Census Bureau provides
the Detailed Feedback Address List sorted based on the following order of the Feedback Code
column: X01, R03, A01, A02, A03, R01, and R02. Within each feedback processing code, the sort
is by the LUCA Review Phase sort order (i.e., tract/block or street name/house number).
Performing this dual sort promotes the records eligible for Appeal to the beginning while
retaining the reference to the sort from the LUCA Review Phase materials. The heading area of
this material identifies the sort option. See Figure 2 for an example of this material for a
fictitious entity.
IMPORTANT:

The Detailed Feedback Address List is the only editable material for the LUCA Feedback
Phase and the “Appeal Flag” column in the Detailed Feedback Address List is the only
editable column.

During the LUCA Review Phase, if participants determined the Census Address List was correct,
had no address updates, and returned either form D-2079 – No Updates or Changes to
Addresses Form or form D-2084 – Submission Deadline Form indicating that they wanted to
receive the LUCA Feedback Phase materials, their Detailed Feedback Address List contains only
the addresses deleted by a different census operation or another level of government
participating in LUCA. If there were no addresses deleted since the LUCA Review Phase,
participants do not receive a Detailed Feedback Address List. Instead they receive a paper insert
(D-2282), mentioned as the footnote in Section 1.1, which notifies them that they did not have
any addresses eligible for Appeal.

2.2.3 Understanding the Feedback Processing Codes
The feedback processing codes in the Detailed Feedback Address List indicate the results of the
Census Bureau processing of participants records submitted during the LUCA Review Phase.
Table 4 identifies the feedback processing code assigned to the records submitted by a
participant. The second column indicates if the code is eligible for Appeal. The third column
gives the Census Bureau’s result of the processing, including information regarding the
acceptance or rejection of the participant’s update and a decision to include or exclude the
address from the 2020 Census.

Feedback
Code

The Feedback Code column of the Detailed Feedback Address List contains the code that
specifies if the Census Bureau accepted or rejected the action submitted by the participant. For
example, A01, A02, and A03 indicates the Census Bureau accepted the address update. These
three feedback processing codes are not eligible for Appeal. Both A01 and A02 records remain
in the 2020 Census enumeration universe and therefore are ineligible for Appeal while the A03
reflects an accepted update that excludes an address from the 2020 Census enumeration
universe (i.e., accepted D, N, and J LUCA actions).
The three “R” feedback processing codes (R01, R02, and R03) indicate the Census Bureau
rejected the updated addresses. Only the R03 is eligible for Appeal. Both R01 and R02 records
remain in the 2020 Census enumeration universe and therefore are ineligible for Appeal.
In addition to records submitted by a participant, the Detailed Feedback Address List may
include addresses that were in the Census Address List during the LUCA Review Phase (not
commented on by the participant), but deleted by a different census operation or another level
of government participating in LUCA. These addresses receive an X01 feedback processing code
and are eligible for Appeal.
IMPORTANT:

Only addresses assigned with feedback processing codes of X01 or R03 are eligible for
Appeal because they are not part of the 2020 Census enumeration universe.

2.2.4 Feedback Processing Code Examples
This section provides only a few examples for each feedback processing code. It documents
some of the most common scenarios encountered during the Census Bureau’s processing of
U.S. Census Bureau

2020 Census LUCA Feedback Paper Respondent Guide

LUCA Review Phase submissions. This list of examples is not a comprehensive list of all the
scenarios that lead to the assignment of feedback processing codes.
X01 – Address removed from the 2020 Census. The Census Bureau will exclude this address
from the 2020 Census for the participant’s jurisdiction. A different census operation or another
level of government participating in LUCA deleted the address. This address was not updated as
part of the participant’s LUCA Review Phase work. (Appeal eligible.)




If a participant did not update the address but an update from a different census operation
deleted it, the participant would see the address as an X01.

R03 – Address is not in the 2020 Census. The Census Bureau will exclude this address from the
2020 Census for the participant’s jurisdiction and rejects the LUCA update. (Appeal eligible.)




A01 – Address is in the 2020 Census in the same block. The Census Bureau will include this
address in the 2020 Census for the participant’s jurisdiction in the same block, and accepts the
LUCA update. (Ineligible for Appeal.)


Participant adds an address (an A action) and the Census Bureau accepts it where the
participant says.



Participant updated a street name or geocode (a C action) and the Census Bureau agrees.

A02 – Address is in the 2020 Census in a different block. The Census Bureau will include this
address in the 2020 Census for the participant’s jurisdiction in a different block, and accepts the
LUCA update. (Ineligible for Appeal.)


Participant adds an address (an A action) and the Census Bureau accepts it in a different block.
This action would receive an A02.



Participant submits an address record as an add (an A action). The Census Bureau has the same
address in a different block within the participant’s jurisdiction. This action would receive an
A02.



Participant updated a street name or geocode (a C action) and the Census Bureau accepts it in a
different block. This action would receive an A02.

A03 – Address is not in the 2020 Census. The Census Bureau will exclude this address from the
2020 Census for the participant’s jurisdiction, and accepts the LUCA update. (Ineligible for
Appeal.)
U.S. Census Bureau

2020 Census LUCA Feedback Paper Respondent Guide



R01 – Address is in the 2020 Census in the same block. The Census Bureau will include this
address in the 2020 Census for the participant’s jurisdiction in the same block, and rejects the
LUCA update. (Ineligible for Appeal.)




Participant submitted the address for deletion (a D action) and the record is a known, valid
residential address from the USPS Delivery Sequence File (DSF). This action would receive an
R01.



Participant submitted the address as non-residential (an N action) and the record is a known,
valid residential address from the USPS DSF. This action would receive an R01.



Participant submitted the address as out of jurisdiction (a J action) and the record is a known,
valid residential address in their jurisdiction from the USPS DSF. This action would receive an
R01.

R02 – Address is in the 2020 Census in a different block. The Census Bureau will include this
address in the 2020 Census for the participant’s jurisdiction in a different block, and rejects the
LUCA update. (Ineligible for Appeal.)


Participant submitted a geocode change (a C action) and the Census Bureau rejects the new
geocode keeping the address in the original location. This action would receive an R02.



Participant submitted a geocode change (a C action) and the Census Bureau chooses “third block”
(meaning the location is not where it was on the LUCA Review Phase materials, NOR where the
participant says, but the Census Bureau moved the record to a third block). This action would
receive an R02.

block, the one submitted by the county. The state’s action would receive an R02. The county’s
action would receive an A01.


Participant submitted the address as non-residential (an N action) and the record is valid nonresidential address in a different block. This action would receive an R02.



Participant submitted the address as out of jurisdiction (a J action) and the record is a valid
residential address in a different block within their jurisdiction. This action would receive an R02.

2.3 Feedback Address Count List (D-2209)
The Census Bureau provides the Feedback Address Count List (D-2209) to participants to show
the change in residential address block tallies between the LUCA Review Phase and the LUCA
Feedback Phase. The list contains the LUCA Review Phase tallies of residential addresses
(housing unit and group quarters) that were on the participant’s Census Address List and the
current number of residential addresses (housing unit and group quarters) in the Census
Address List for each census block within the jurisdiction. It is important to realize that tally
differences do not indicate lack of coverage. It could indicate a change to geocoding between
census blocks in your jurisdiction. The tally differences may also be the result of work
performed during other census operations. There is no direct link between change in tallies on
the Feedback Address Count List and Appeal eligibility for individual address records on the
Detailed Feedback Address List.
The printed Feedback Address Count List is on 8 ½ x 11 inch (letter size) paper with 24 rows per
page, divided into two sections for a total of 48 blocks per page. Each section includes seven
columns of information. The last page contains a “Total” row at the bottom that summarizes
each of the four “count” columns. The Census Bureau provides the Feedback Address Count List
sorted based on the State County Code, Census Tract, and Census Block columns. See Figure 3
for an example of this material for a fictitious entity

2.5 Paper Maps, PDF maps, and Shapefiles
The Census Bureau provides paper maps and/or PDF maps, or shapefiles during the LUCA
Feedback Phase, according to the final format that the participant selected for the LUCA Review
Phase. Participants use the maps for geocoding reference and for review of any map updates
submitted during the LUCA Review Phase. Maps may include feature updates provided by the
submitting entity, other LUCA participants, and/or other updates found by the Census Bureau
during other census operations. Map legends for both the large format maps and the small
format block maps closely resemble the legends used during the LUCA Review Phase, with
minor changes made to symbology to reflect Appeal-eligible address records and the two types
of residential addresses (housing units and group quarters). Blue circles or blue squares, that
represent housing units or group quarters respectively, show the Appeal-eligible records while
gray symbols of the same style show records ineligible for Appeal. For examples of a small
format block map (e.g., PDF maps) with the updated map symbols, see Figure 5 and Figure 6.
Refer to the 2020 Census Local Update of Census Addresses Operation (LUCA) Respondent
Guide; Paper Address List Format (D-2031) included with the original LUCA Review Phase
materials for details on the large format maps, small format block maps, shapefiles, and the
block to map sheet relationship list.8 This guide does not repeat all of the map-related
information in D-2031 since the feedback map materials are reference material for geocoding
purposes only. Locate a copy of the D-2031 on the LUCA website at
.
IMPORTANT:

Participants may not submit map or shapefile updates during the LUCA Feedback Phase
due to 2020 Census operational scheduling.

Chapter 3, The LUCA Paper Maps and Chapter 5, TIGER Partnership Shapefiles provide detailed examples and information.

CHAPTER 3. HOW TO FILE AN APPEAL
This chapter provides information on the process to Appeal addresses while reviewing the 2020
Census LUCA feedback materials. The Federal Register notice on the 2020 Census LUCA Appeals
Process forms the basis for much of the content in this chapter. A copy of the Federal Register
notice is included in the feedback materials package or can be located on LUCA website at
.

3.1 Background
To ensure that tribal, state, and local governments participating in 2020 Census LUCA have a
means to Appeal the Census Bureau’s determinations, the Census Address List Improvement
Act of 1994 requires that the Administrator of OMB’s Office of Information and Regulatory
Affairs (OIRA), acting through the Chief Statistician and in consultation with the Census Bureau,
develop an Appeals Process by establishing a temporary federal entity, the 2020 Census LUCA
Appeals Office. This office will resolve any disagreements that may remain after participating
governments receive the Census Bureau’s LUCA Feedback materials and make a final decision
on the inclusion of appealed addresses. Participants must contact staff in the 2020 Census LUCA
Appeals Office, not the Census Bureau, for specific Appeal-related questions. Reach the Appeals
Staff toll-free, by phone, at (888) 222-9907.

3.2 Deadline for Filing an Appeal
The deadline for filing an Appeal is 45 calendar days after the date the participant receives their
feedback materials from the Census Bureau. The 2020 Census LUCA Appeals Office defines
“receipt” as the delivery date reported to the Census Bureau by the delivery service carrier.
In order to safeguard the confidential address materials covered by Title 13, the submission of
an Appeal to the Appeals Staff must adhere to the Census Bureau's specific guidelines for
handling materials supplied with the feedback materials. The participant must submit its Appeal
materials to the Appeals Staff following the instructions outlined in Section 3.5, and should
keep a record of the date it submits these materials in case there are questions about the
submission date. The participant may not submit any materials to the Appeals Staff after the 45
calendar day period has elapsed.
Upon receipt of an Appeal, the Appeals Staff will send a confirmation of receipt to the
participant. They also will notify the Census Bureau that a participant has filed an Appeal.

3.3 Procedures for Filing an Appeal
A participant is eligible to file an Appeal if they returned address additions or corrections to the
Census Address List during the LUCA Review Phase, or if they certified, after review, that the
Census Address List was correct and required no updates. A participant may Appeal the
following types of addresses:


U.S. Census Bureau

2020 Census LUCA Feedback Paper Respondent Guide

feedback processing code in column 5 (Feedback Code). The 2020 Census enumeration universe
excludes these records.


IMPORTANT REMINDER:

Only the X01 and R03 address records are eligible for Appeal.

As mentioned in Section 2.2, to facilitate the participant’s feedback review, the Census Bureau
provides the Detailed Feedback Address List sorted based on the following order of the
Feedback Code column: X01, R03, A01, A02, A03, R01, and R02. Within each feedback
processing code, the sort is by the LUCA Review Phase sort order (i.e., tract/block or street
name/house number). Performing this dual sort promotes the Appeal-eligible records to the
beginning while retaining the reference to the sort from the LUCA Review Phase materials.
For each X01 and R03 coded address record on the Detailed Feedback Address List that the
participant believes should be reinstated in the Census Address List, insert a ”Y” in column 1
(Appeal Flag) for that address.

3.4 Supporting Documentation
The 2020 Census LUCA Appeals Office requires eligible participants to provide evidence of
existence and the location for appealed addresses. To this end, eligible participants must
provide the supporting documentation for all appealed addresses as specified below.
For the 2020 Census LUCA Appeals process, participants may apply the same set of supporting
evidence to a group of addresses. For example, participants may wish to supply one set of
supporting evidence for related addresses such as those associated with a single housing
development or complex if the set of supporting evidence substantiates the existence of the full
set of linked addresses. In other cases, a written description of a robust process to review and
verify the Appeal-eligible addresses using highly accurate sources may support a set of
addresses. Participants must supplement this narrative with a selection of appealed addresses
associated with an exact location and proven with one of the evidence types listed below.
Eligible governments must submit the following supporting documentation with their Appeal:


A written narrative with an explanation of the eligible government’s position for why the
Appeals Staff should adopt their recommendation.



U.S. Census Bureau

2020 Census LUCA Feedback Paper Respondent Guide



For each address on the Detailed Feedback Address List that the participant is appealing, write
(or key if the supporting documentation is in digital format) the Appeal Flag from column 1 and
the line number from column 2 (Line #) on the supporting documentation to show the exact
location in the document where the evidence for that address is located. For example, if
submitting property tax records that contain 30 tax records per page, print (or key) the Appeal
Flag and Line # (e.g., “Y4” if the Appeal-eligible record was line number 4 of the Detailed
Feedback Address List) on the one tax record among those 30 tax records that supports the
Appeal.
Only submit documentation specific to the addresses being appealed, e.g., one property tax
record or one utility record for each appealed address or only those pages of a list with the
records for the appealed addresses appropriately marked. If a supporting document validates
the existence of multiple appealed records, participants must develop a method for linking the
supporting evidence to the appealed address or group of appealed addresses. Whatever
method a participant chooses to associate source material with their appealed records, it is
crucial for the Appeals Staff to be able to determine which evidence supports which address
records or set of address records in order to process the Appeal.
Direct questions on the Appeals process to the 2020 Census LUCA Appeals Office toll-free, by
phone, at (888) 222-9907. The LUCA website, , also lists their contact information.

3.5 Preparing and Submitting Appeal Materials to the 2020 Census LUCA
Appeals Office
To file an Appeal, participants must submit a hard copy of their written narrative and of their
pages of the Detailed Feedback Address List with records flagged for Appeal as described below
in Section 3.5.1. They may choose to include hard copies of their source description(s) and
supporting documentation or they may choose to include a CD or DVD with digital copies of
their supporting documentation and source description(s) to accompany their hard copy
Detailed Feedback Address List pages and written narrative.

U.S. Census Bureau

2020 Census LUCA Feedback Paper Respondent Guide

3.5.1 Preparing Appeal Materials for Submission
After completing the review of the LUCA Feedback Phase materials and flagging some records
for Appeal, return only the pages of the Detailed Feedback Address List that contain records
with a “Y” in the Appeal Flag column. Please do not return unedited pages to the 2020 Census
LUCA Appeals Office; doing so complicates their review. Make, and retain, a copy of the edited
pages for reference while the Appeals Staff conducts their work. Once the Appeals process
completes, participants must destroy or return these materials to the Census Bureau as part of
the Closeout Phase discussed in Chapter 4.
Prepare a written narrative with the explanation of the participant’s Appeal to the 2020 Census
LUCA Appeals Office. The narrative should outline the basis of the Appeal and the participant’s
position for why the 2020 Census LUCA Appeals Office should adopt the recommendations. The
narrative should provide the contact information for the Appeal, including:




The name of the governmental jurisdiction filing the Appeal.
The name, mailing address, telephone number, and email address (if any) for the jurisdiction’s
contact person for the Appeal. Ensure this person is on the D-2005 – Confidentiality Agreement
Form.
An inventory of the supporting documentation pages/materials enclosed (e.g., submitting four
pages of supporting documentation for 15 appealed records or submitting three documents that
denote support for 15 appealed records). Consider including a brief summary of how to navigate
the documentation in conjunction with the Detailed Feedback Address List.

The detailed description(s) of the address source(s) can be included within the written narrative
or within separate documentation. If participants use more than one source, they must be sure
to detail the differences between the sources and identify how they used the sources during
the Appeals process.
Organize the supporting documentation. Retain a copy (digital and/or hard copy) of the
supporting documentation to retain for reference in case the Appeals Staff have questions
about the submitted materials.

3.5.2 Shipping Instructions for Submitting Appeal Materials
Participants ship their hard copy materials and their CD or DVD of their digital information, if
applicable, using the following instructions to package and ship materials to the 2020 Census
LUCA Appeals Office:




Label both sides of the inner envelope (or container) with the notice:
“DISCLOSURE PROHIBITED BY TITLE 13, U.S.C.”



Place the inner envelope (or container) into the outer envelope.

CHAPTER 4. 2020 CENSUS LUCA CLOSEOUT
The Census Bureau must account for all Title 13 material delivered to participants during both
the LUCA Review Phase and Feedback Phase, and any copies of those materials, to close out the
operation for 2020. It is the responsibility of the LUCA liaison to ensure the proper disposal of
the Title 13 material. The designated liaison is required to verify the destruction or return of
any remaining Title 13 materials, both paper and digital (i.e., paper copies, backup files, etc.) by
signing and returning to the Census Bureau the D-2012 – Destruction or Return of Title 13, U.S.C.
Materials Form enclosed with the feedback materials and found in Appendix C. The destruction
of materials is the preferred method rather than returning the materials to the Census Bureau.
IMPORTANT:

Please await a response from the 2020 Census LUCA Appeals Office on the status of the
Appeal prior to destroying or returning the Title 13 material.

All LUCA reviewers and anyone with access to Title 13 materials (includes all persons who
signed the D-2005 – Confidentiality Agreement Form) are required to sign and date the D-2012
form once the LUCA Appeals process concludes. Should any liaison, reviewer, or anyone with
access to Title 13 materials leave before the completion of the LUCA operation, they are
required to sign out of the program by signing and dating this form. If any liaison or reviewer
leaves and fails to sign and date this form, the current liaison can sign out on their behalf.
Participants choosing to destroy their materials must return the D-2012 as soon as possible
after the destruction of materials and must ensure the form contains all appropriate liaison and
reviewer signatures to close out 2020 Census LUCA. Use the enclosed, postage-paid envelope
to return the D-2012. Participants choosing to return their materials, rather than destroy them,
must include this form with the materials and must follow the packaging and shipping
instructions in Appendix A to ensure the security of the Title 13 materials.

APPENDIX A. CONFIDENTIALITY AND SECURITY GUIDELINES
A1

Introduction

Federal law, under Title 13 of the United States Code (U.S.C.), requires the U.S. Census Bureau
to maintain the confidentiality of the information it collects. The Census Bureau takes this
responsibility very seriously. Respondents place their trust in the Census Bureau each time they
complete a survey or an interview. This trust in confidentiality is critical to the success of the
Census Bureau’s mission to collect and report the most accurate data possible. To uphold the
law, the Census Bureau requires that any individuals with access to Title 13 materials adhere to
the prescribed confidentiality and security guidelines.

Title 13, U.S. Code

In 1994, under Public Law 103-430, the U.S. Congress amended Chapter 1 of Title 13 to allow
the local government census liaison to review and update the Census Bureau’s address
information for their jurisdiction. Although the amendment allows official local government
access, the amendment reaffirmed the confidential nature of the Census Bureau’s address
information. Census information protected under Title 13 includes:


Everything on a completed or partially completed questionnaire or any information obtained in
a personal or telephone interview.



Individual addresses maintained by the Census Bureau, including those shared with
governments through the 2020 Census Local Update of Census Addresses Operation (LUCA).



Digital or paper maps with latitude/longitude coordinate data that identify the location of living
quarters (structure points).



Title 13 U.S.C. does not apply to generalized address information, such as address range data
available in the Census Bureau’s digital products or address counts by census block.

The Confidentiality Agreement

2020 Census LUCA Feedback Paper Respondent Guide

A-1

The Census Bureau will not deliver LUCA materials to a participant until we have received the
completed and signed Confidentiality Agreement and the Confidentiality and Security Checklist.
The Census Bureau’s Title 13 data, including addresses and latitude/longitude coordinate data
(structure points), cannot be used to create, update, nor modify a tribal, state, or local
jurisdiction’s address list or database.
A signature on the Confidentiality Agreement constitutes a legal agreement by each individual
to keep confidential Census Bureau Title 13 data and abide by the security guidelines outlined
below. While access to Title 13 materials is temporary, the commitment to keep the
information confidential is effective for a lifetime.

Security Guidelines

The LUCA liaison accepts the responsibility for protecting and safeguarding the LUCA materials.
The liaison must restrict access to the Census Bureau’s information covered under Title 13 to
those individuals who have signed the Confidentiality Agreement.

A4.1

Protecting Digital Title 13 Materials

Operating systems, programs, applications, and data are collectively referred to as Information
Technology (IT) systems in this document. Any IT systems used for LUCA participation must be
accessible only to those who have signed the Confidentiality Agreement. Your IT systems should
restrict the read, write, and delete functions to all Title 13 materials.
Digital Guidelines


Construct electronic security profiles to allow only the LUCA liaison and the LUCA reviewers to
access Title 13 materials. Test your security to ensure that access is restricted.



Use file encryption and passwords to protect all digital Title 13 materials at all times. Encrypt
files using the Advanced Encryption Standard (AES) with key length of 256 bits.



Do not leave computers with Title 13 materials unattended. Log-off computers, lock terminals,
and lock the room when not in use.



Label all digital media and every printed page of any paper materials produced from Title 13
digital media with the following:

“This document contains information, the release of which is prohibited by Title 13,
U.S.C., and is for U.S. Census Bureau official use only. Wrongful disclosure or release of
information can be punished by fine or imprisonment (Public Law 99-474).”


Do not send backup digital media off-site. Store in a secured area. Do not mix, store, or back-up
LUCA data with other data.



Clear dedicated digital media containing Title 13 materials before reuse. Overwrite Title 13
digital data minimally three times using a commercial disk utility program.



Do not disclose precise or even anecdotal information about Census Bureau addresses or
locations to anyone who has not signed the Confidentiality Agreement.

U.S. Census Bureau

2020 Census LUCA Feedback Paper Respondent Guide

Password Guidelines
The IT systems must use logon routines that require a user-ID and password that conform to
the following guidelines:


Unique user-ID and password required for the LUCA liaison, the LUCA reviewers, and anyone
who has signed the Confidentiality Agreement.



Must consist of at least twelve, nonblank characters consisting of at least one alphabet letter
and either one number or one special character (for example: $,*, or &).



Reject passwords that are the same as the user-ID or that have been used within the last six
months.



Disable passwords after three failed attempts.



Mask passwords.



Require password changes every 90 days or immediately, if compromised.



Require user to change an assigned password to a unique password the first time the user
accesses a new account.

A4.2

Protecting Paper Title 13 Materials



Do not leave Title 13 materials unattended. Secure all Title 13 materials in a locked room. If
possible, store Title 13 materials in locked desks or cabinets.



A4.3

Do not disclose precise or even anecdotal information about Census Bureau addresses or
locations to anyone who has not signed the Confidentiality Agreement.

Reporting an Incident

If you discover that any Title 13 materials have been viewed by unauthorized persons or are
missing from your inventory, you must:

A4.4

On-site Visits

The Census Bureau may make an on-site visit to review a participant’s security procedures. The
Census Bureau will strive not to disrupt office operations. A visit may include a review of:


Storage and handling of Title 13 materials.



Employee access to Title 13 materials.



Physical safeguard of stored Title 13 materials.



IT Systems, including use of passwords.

A4.5

Destruction of Census Bureau Confidential Materials

After the entire LUCA operation has concluded, all Title 13 materials must be destroyed
(preferred method) or returned according to the Census Bureau’s specific guidelines. The LUCA
liaison is required to verify the destruction or return of any Title 13 materials, both paper and
digital, including all paper copies, backup files, etc., by signing and returning the Destruction or
Return of Title 13, U.S.C. Materials form. In addition, anyone who signed the Confidentiality
Agreement is required to sign this form once his or her participation in LUCA has ended. Should
any liaison, reviewer, or anyone who signed the Confidentiality Agreement leave before the
completion of LUCA, they must sign and date this form. If any liaison, reviewer, or anyone who
signed the Confidentiality Agreement is unable to sign and date the form, the current liaison
must sign and date on their behalf.
Only individuals who signed the Confidentiality Agreement are permitted to destroy Title 13
materials:


Never deposit Title 13 materials in a trash or recycle container, or dispose of information in a
landfill before destruction procedures are completed.



Note: Hand tearing is an unacceptable method of Title 13 material disposal before destruction.

A4.6

Returning Census Bureau Title 13 Materials

After the entire LUCA operation has concluded, all Title 13 materials must be destroyed
(preferred method) or returned according to the Census Bureau’s specific guidelines. If you
decide to return the Title 13 materials rather than destroying them, follow these guidelines:




Label both sides of the inner envelope (or container) with the notice:

“DISCLOSURE PROHIBITED BY Title 13, U.S.C.”


Place the inner envelope (or container) into the outer envelope.



Use the mailing label that was included in the initial mail-out of materials. If you have
misplaced the mailing label, please contact the Census Bureau to have a replacement label sent
to you.



If you do not use the mailing label, ship using a service that provides tracking information, such
as U.S. Postal Service trackable delivery, FedEx, United Parcel Service (UPS), or similar service.

APPENDIX D. GLOSSARY
Address Count List—This material was included as part of the LUCA Review Phase materials. It
identified the number of housing unit addresses and group quarters addresses on the Census
Address List for each census block within a jurisdiction.
Address range—The lowest and highest address numbers used to identify structures along each
side of a street segment that has city style addresses. Usually one side of the street has even
address numbers and the other side has odd address numbers.
Block to Map Sheet Relationship List—This material was included as part of the LUCA Review
Phase materials. It identified census block numbers and the Census Bureau large format map(s)
on which each block is located.
Boundary—A line, on a map, either invisible or coincident with a visible feature that identifies
the extent of a geographic entity, such as a census tract, city, county, or state. A boundary
marks the limits of an area.
Census Address List—This material was included as part of the LUCA Review Phase materials.
The Census Address List, extracted from the Master Address File (MAF) for review and update
during 2020 Census LUCA, contains all the residential addresses (city style and non-city style)
known to the Census Bureau for your government. It also contains census geographic codes
(state, county, census tract, census block) that indicate the location of each address. Many
addresses also contain latitude and longitude coordinates depicting the address location.
Census block—A census block is an area bounded by visible and/or invisible features shown on
Census Bureau maps. A census block is the smallest geographic area created by the Census
Bureau for which it collects and tabulates decennial census data. Census blocks are numbered
within census tracts and are uniquely numbered within census tracts.
Census block number—Census block numbers are a four-digit number. Census blocks are
numbered uniquely within each census tract.
Census Bureau—An agency within the U.S. Department of Commerce. The U.S. Census Bureau
is the country's preeminent statistical collection and dissemination agency. It publishes a wide
variety of statistical data about people and the economy of the nation. The Census Bureau
conducts approximately 200 annual surveys and conducts the decennial census of the United
States population.
Census Bureau map—Any map produced by the Census Bureau. A Census Bureau map displays
geographic entities used in a Census Bureau sponsored census or survey for which the Census
Bureau tabulates data.
Census tract—A small, relatively permanent statistical subdivision of a county or statistically
equivalent entity delineated for data presentation. Designed to be relatively homogeneous
units with respect to population characteristics, economic status, and living conditions at the
time of establishment, census tracts generally contain between 1,000 and 8,000 people, with
an optimum size of 4,000 people. Delineated with the intention of being stable over many
decades, census tract boundaries generally follow relatively permanent visible features.
U.S. Census Bureau

2020 Census LUCA Feedback Digital Respondent Guide

D-1

However, they may follow governmental unit boundaries and other invisible features in some
instances; the boundary of a state or county (or statistically equivalent entity) is always a
census tract boundary.
Census tract number—Unique numbers to identify census tracts within a county or statistically
equivalent entity. Census tract numbers are a four-digit number followed by a decimal point
and a two-digit number for suffixed tracts, e.g., 1234.01. For census tracts without a suffix, the
number will contain a period with zero fill, e.g., 4567.00. Leading zeros for census tracts, e.g.,
0001.00, are not shown on Census Bureau maps. This tract would appear as “1” on the paper
maps.
City style address—The Census Bureau’s definition of a city style address is an address
consisting of a house number and street or road name. For example, 201 Main Street is a city
style address. The address may or may not be used for the delivery of mail and may include
apartment numbers/designations or similar identifiers.
Confidentiality—The guarantee made by law (Title 13, United States Code) to individuals who
provide information about themselves or their business to the Census Bureau. This item refers
to the Census Bureau’s promise of nondisclosure of that information to others.
County—The primary legal division of most states. Most are governmental units with powers
defined by state law.
Detailed Feedback Address List— A hard copy address list generated by the Census Bureau that
shows all accepted (i.e., properly formatted) address record updates submitted by the
participant during the LUCA Review Phase and a feedback processing code identifying a specific
action taken by the Census Bureau on that address record. This address list also identifies any
address records not commented on and deleted from the original Census Address List by a
different census operation or another level of government participating in LUCA.
Edges—All linear features contained in the MAF/TIGER database.
Edges shapefile— An Esri® shapefile of the linear features contained in the MAF/TIGER
database During the LUCA Review Phase, participants using digital map materials used the
edges shapefile to add, delete, or change linear feature attributes. During the LUCA Feedback
Phase, participants use the edges shapefile for reference only to review updates they made
during the LUCA Review Phase or other updates made since the LUCA Review Phase concluded.
Enumeration at Transitory Locations (ETL) operation—Provides coverage for locations where
people live in non-traditional housing that is transient or movable in nature. Most census
questionnaires are mailed, or hand-delivered by census personnel, to known addresses in the
Census Master Address File (MAF). However, due to changes in society, some people no longer
maintain a traditional residence (house, apartment, condo, etc.), and have decided to live in
boats, motorized recreational vehicles (RVs), trailers that are pulled by car or trucks, or any
other type of housing that is movable or mobile, including tents. For operational purposes, we
refer to these as “portable housing units.”
The type of Transitory Locations (TLs) that are included in the ETL are:


Recreational (RV) parks.

Campgrounds.

Feature—Any part of the landscape, whether natural (such as, a stream or ridge) or man-made
(such as a road or power line). In a geographic context, features are any part of the landscape
portrayed on a map, including nonvisible boundaries of legal entities, such as city limits or
county lines.
Federal Information Processing Series (FIPS)—These are codes formerly known as Federal
Information Processing Standards codes, until the National Institute of Standards and
Technology (NIST) announced its decision in 2005 to remove geographic entity codes from its
oversight. The Census Bureau continues to maintain and issue codes for geographic entities
covered under FIPS oversight, albeit with a revised meaning for the FIPS acronym. Geographic
entities covered under FIPS include states, counties, congressional districts, core based
statistical areas, places, county subdivisions, sub-minor civil divisions, consolidated cities, and
all types of American Indian, Alaska Native, and Native Hawaiian areas. FIPS codes are assigned
alphabetically according to the name of the geographic entity and may change to maintain
alphabetic sort when new entities are created or names change. FIPS codes for specific
geographic entity types are usually unique within the next highest level of geographic entity
with which a nesting relationship exists. For example, FIPS state, congressional district, and core
based statistical area codes are unique within nation; FIPS county, place, county subdivision,
and sub-minor civil division codes are unique within state. The codes for American Indian,
Alaska Native, and Native Hawaiian areas also are unique within state; those areas in multiple
states will have different codes for each state.
Feedback Address Count List— A hard copy address count list or comma-delimited text file,
in .csv format, containing the number of housing unit and group quarters residential addresses
on the LUCA Review Phase Census Address List and the current number of housing units and
group quarters residential addresses for each census block within the participant’s jurisdiction.
This product accompanies the Feedback Phase materials.
Feedback Block to Map Sheet Relationship List—This material is included as part of the
Feedback Phase materials. It identifies census block numbers and the Census Bureau large
format map(s) on which each block is located.
Geocodes—Codes that place an individual address in its correct geographic location, which, in
census terms, includes the correct state, county, census tract, and census block codes. Because
the Census Bureau counts people where they live, geocodes provide information to Census
enumerators for locating an address. Accurate geocoding also ensures the Census Bureau
counts housing units, and the people associated with them, in the correct census geography.
Geographic Information System (GIS)—A computer system for the storage, retrieval, and
maintenance of information about the points, lines, and areas that represent the streets and
roads, rivers, railroads, geographic entities, and other features on the surface of the Earthinformation that previously was available only on paper maps.
Geographic Update Partnership Software (GUPS)—A self-contained GIS update and processing
package provided by the Census Bureau for participation in a variety of Census geography
programs, including 2020 Census LUCA. Pre-packaged to include all of the components for 2020
U.S. Census Bureau

2020 Census LUCA Feedback Digital Respondent Guide

D-3

Census LUCA, the GUPS contains the Detailed Feedback Address List, Feedback Address Count
List, and TIGER Partnership shapefiles for the LUCA Feedback Phase. It contained the Census
Address List, address count list, and TIGER Partnership shapefiles for use during the LUCA
Review Phase. GUPS allows the participant to add external geospatial data (shapefiles,
geodatabases, and imagery) for comparison and update purposes. Delivery of all data (software,
address list, address count list and shapefiles) is on DVD.
Governmental unit (GU)—A geographic entity established by legal action for the purpose of
implementing specified governmental functions. Most governmental units provide a number of
general government services and raise revenues (usually through taxing authority).
Group quarters (GQ)—A place where people live or stay normally owned or managed by an
entity or organization providing housing and/or services for the residents. These services may
include custodial or medical care as well as other types of assistance, and residency is
commonly restricted to those receiving these services. People that live in a group quarters are
usually not related. Group quarters include such places as college residence halls, residential
treatment centers, skilled nursing facilities, group homes, military barracks, correctional
facilities, workers’ dormitories, and facilities for people experiencing homelessness.
Highest elected official (HEO)—The person most responsible for the governmental activities of
a local government. This person receives the LUCA invitation letter, and must designate a LUCA
liaison, to participate in the 2020 Census LUCA Operation.
Housing unit (HU)—A single-family house, townhouse, mobile home, trailer, apartment, group
of rooms, or a single room occupied as a separate living quarters or, if vacant, intended for
occupancy as a separate living quarters. A separate living quarters is one in which one or more
occupants (or intended occupants, if vacant) live separate from any other individual(s) in the
building and have direct access to the living quarters without going through another living
quarters, such as from outside the building or through a common hall.
Living quarters—Any site where people live, stay, or could live. Living quarters are classified as
housing units or group quarters. They are usually found in structures intended for residential
use, but also may be found in structures intended for non-residential use as well as tents, vans,
shelters for people without housing, dormitories, barracks, and so forth, or they might not be
associated with a structure at all.
LUCA liaison—The main point of contact appointed by the highest elected official (HEO) of each
jurisdiction to review the Census Address List and maps against local records to identify
differences. This person, also known as the program primary liaison or designated liaison,
accepts responsibility for safeguarding Title 13 materials and are ultimately responsible for
destroying (or returning) the materials. They must sign out of LUCA and submit the Destruction
or Return of Title 13 Materials Form (D-2012) after ensuring all LUCA reviewers sign the form as
well.
LUCA reviewer—Individual(s) selected by the HEO or LUCA liaison to assist with conducting the
LUCA review. They accept responsibility for safeguarding Title 13 materials and, like the liaison,
must sign out of LUCA and submit the Destruction or Return of Title 13 Materials Form (D-2012).
Master Address File (MAF)—The Census Bureau’s nationwide database of all addresses and
U.S. Census Bureau

2020 Census LUCA Feedback Digital Respondent Guide

D-4

physical/location descriptions known to the Census Bureau used to support many of the Census
Bureau’s operations. Besides containing mailing addresses and ZIP Codes, a MAF record also
contains geographic information about the location of addresses. The Census Bureau’s
Geography Division regularly updates the MAF/TIGER database from various sources, including
the United States Postal Service (USPS) Delivery Sequence File (DSF) and other sources of
updates such as current surveys and locally provided sources.
MAF/TIGER Database (MTDB)—The Census Bureau’s nationwide geographic database, which
integrates the Master Address File (MAF) and Topologically Integrated Geographic Encoding
and Referencing (TIGER) files.
Metadata—Describes the data content, coordinate system/projection, author, source, and
other characteristics of GIS files.
Minor civil division (MCD)—The primary governmental or administrative division of a county in
29 states and the Island Areas having legal boundaries, names, and descriptions. The MCDs
represent many different types of legal entities with a wide variety of characteristics, powers,
and functions depending on the state and type of MCD. In some states, some or all of the
incorporated places also constitute MCDs. MCDs are identified by a variety of terms, such as
town (in eight states), township, and/or district. They include both functioning and
nonfunctioning government entities.
Non-city style address—An address that does not have a house number and/or street name or
may not include a complete house number and street name address. This includes rural route
and box number address and highway contract route addresses, etc., which may include a box
number, post office boxes and drawers, and general delivery.
Occupied housing unit—A housing unit is classified as occupied if it is the usual place of
residence of the individual or group of persons living in it at the time of enumeration or if the
occupants are only temporarily absent; for example, away on vacation. Occupied rooms or
suites of rooms in hotels, motels, and similar places are classified as housing units only when
occupied by permanent residents, that is, individuals for whom the facility is their usual place of
residence.
Place—A concentration of population either legally bound as an incorporated place,
consolidated city, or identified by the Census Bureau as a census designated place.
Regional Census Center (RCC)—Temporary offices set up approximately two years prior to the
decennial census. The geographic staff from the Regional Offices are assigned to their
respective RCC and assist with the execution of various geographic operations as well as
provide support for the field operations conducted during the decennial.
Regional Office (RO)—One of six permanent Census Bureau offices distributed across the
nation. Regional offices are responsible for the Census Bureau’s field operations.
Shapefile—Digital representations of geographic features, such as roads and boundaries used
to create maps. A shapefile stores non-topological geometry and attribute information for the
spatial features in a dataset. The Census Bureau provides county-based shapefiles in Esri
shapefile format.
U.S. Census Bureau

Street segment—The portion of a street or road between two features that intersect that
street or road, such as other streets or roads, railroad tracks, streams, and governmental unit
boundaries. The Census Bureau records the known address ranges for every street segment
with city style addresses.
Structure Point (map spot)—A dot on a Census Bureau map, used to show the location of one
or more living quarters. A maximum of four digits plus one alpha character is assigned within a
census block to each structure point. Structure points are stored in the TIGER database and are
protected by Title 13 U.S.C.
Topologically Integrated Geographic Encoding and Referencing (TIGER)—The Census Bureau’s
digital map, including the geographic coordinates and names of streets, water features, other
linear features, and boundaries for all jurisdictions and statistical areas that provide the
geospatial framework for collecting and tabulating census data. TIGER also contains the
structure coordinates of address records in the Master Address File (MAF) and address ranges
along street features used for geocoding MAF records to census geography.
Transitory locations (TL)—Movable or mobile housing, or portable housing units, including
boats, motorized recreational vehicles (RVs), tents, trailers that are pulled by cars or trucks, or
any other type of portable housing.
Vacant housing unit—A habitable structure containing living quarters that is not occupied. New
housing units not yet occupied are classified as vacant housing units if construction has reached
a point where exterior windows and doors are installed and final usable floors and a roof are in
place. Vacant units are excluded if they are open to the elements, or if there is positive
evidence, such as a sign on the house, that the housing unit is to be demolished or has been
condemned.

Feedback Block to Map Sheet Relationship List (D-2210). This identifies the large format parent map sheet(s) or inset sheet(s) on which
each census block is located.
•
Feedback Maps. Provided during the LUCA Feedback Phase according to the final format (paper maps and/or PDF maps or shapefiles)
that the participant selected for their LUCA Review Phase. Participants use the maps for geocoding reference and for reviewing map
updates submitted during the LUCA Review Phase. These are for reference only and not for edit during the LUCA Feedback Phase.
The LUCA Feedback Phase package for some participants may include a paper insert (D-2282) that explains the absence of their Detailed
Feedback Address List from their feedback materials. For participants receiving a DVD as part of their feedback materials, a corresponding file
(2020LUCA_FB_insert.pdf) will be included on the DVD. This file is absent from the images included in this quick start guide because it does
not exist for all participants.

II. Reviewing the LUCA Feedback Phase paper address related materials
•

•

Review the Feedback Address Update Summary Report (D-2201) to understand actions taken by the Census Bureau. It shows the tallies of
actions taken by the Census Bureau for all of the address updates submitted during the LUCA Review Phase and the total number of
address records deleted from the original Census address list by other LUCA participants or other Census operations. Use it to determine
the number of records eligible for appeal.
Use the Feedback Processing Codes, described in Chapter 2 of the respondent guide, to determine the specific action taken by the Census
Bureau for each address update submitted by the participant on the Detailed Feedback Address List (D-2202). Follow the instructions in
Chapter 3 of the respondent guide for flagging addresses for appeal on this material.
Consider reviewing blocks on the Feedback Address Count List (D-2209) with tally differences to determine if any contain address records
that are eligible for appeal. Please note, however, there is no direct link between a change in tallies on the Feedback Address Count List
and appeal eligibility for individual address records on the Detailed Feedback Address List.

III. Extracting the PDF Maps (instructions for the Paper Address List and Large Format Paper/PDF Maps product preference)
The LUCA Feedback Phase package for participants that chose the Paper Address List
and Large Format Paper/PDF Maps product preference includes a Title 13 Data
Disc DVD with PDF small format block maps. A password, mailed separately from the
feedback materials, is required to open the encrypted file located within the “maps”
folder. The root directory of the DVD also contains digital copies of the paper materials
included in the LUCA Feedback Phase package.

review.
Please note that there are no eligible addresses to appeal in your jurisdiction for one
of the following reasons:
•

The Census Bureau was unable to process your updates in the submitted
format. We attempted to contact you, but were unable to reach you for
resolution.
Or
