Introduction
Public Law (P.L.) 94-171 stipulates that the U.S. Census Bureau work in a nonpartisan
manner with the states to identify and provide the small-area population counts
necessary for legislative redistricting. The Census Bureau is required to provide these
counts within one year of Census Day, to the governor and the officers or public bodies
responsible for redistricting in each state. For the 2020 Census, the Census Bureau
must deliver the counts by April 1, 2021.
The Census Redistricting & Voting Rights Data Office (CRVRDO) implements the
requirements of P.L. 94-171 through five phases of the Redistricting Data Program
(RDP):
Phase 1: Block Boundary Suggestion Project (BBSP)
Phase 2: Voting District Project (VTDP)
Phase 3: Delivery of the 2020 P.L. 94-171 Redistricting Data Files
Phase 4: Collection of Post-2020 Redistricting Plans
Phase 5: Review of 2020 Census RDP and Recommendations for Census 2030
This document addresses Phase 1: Block Boundary Suggestion Project (BBSP) of the
RDP. The Census Bureau conducted initial BBSP from December 2015 – May 2016.
The Census Bureau is conducting BBSP Verification (BBSPV), when states who
submitted updates in initial BBSP have the opportunity to review their work, and all
states have the opportunity to submit additional updates, from December 2016 – May
2017. Through the BBSP, liaisons designated by the legislative leadership in each state,
the District of Columbia, and Puerto Rico, have the opportunity to influence the
delineation of the 2020 Census tabulation blocks. States influence tabulation block
delineation by suggesting linear features (e.g., roads, rivers, railroads, invisible
boundaries, etc.) to be ‘held’ as 2020 block boundaries or ‘not held’ as block boundaries.
The Census Bureau refers to this as ‘suggesting’ block boundaries or ‘setting’ or
‘flagging’ ‘Must Holds’ or ‘Do Not Holds’ on the features. State participants can also
influence block boundaries by adding and deleting linear features or edges, and
updating boundaries for other Census geographic entities, including incorporated places,
minor civil divisions (MCD), counties, area landmarks and area hydrography. All of these
features are potential block boundaries.
This guide is intended for state participants who choose to use their own Geographic
Information System (GIS) software, rather than the Geographic Update Partnership
Software (GUPS), for modifying the Census Bureau supplied shapefiles. The GUPS is
the Census Bureau’s recommended tool for submission and review of block boundary
suggestions. It is strongly recommended that BBSP participants use GUPS. For more
information on GUPS, please contact the CRVRDO at 301-763-4039 or
[email protected].
This document assumes that if you are not using GUPS, you are skilled in the use of
your own GIS software. Regardless of whether you plan to use GUPS or your own GIS,
the Census Bureau requires that entities update Census Bureau shapefiles, rather than
submitting a locally derived shapefile from an in-house GIS.

1. Planned 2020 Census Tabulation Block Boundaries
Census tabulation block boundaries primarily follow visible features, such as roads and
rivers, as well as any edges that bound legal or statistical geographic areas or selected
area landmarks stored in the Master Address File/Topologically Integrated Geographic
Encoding and Referencing (MAF/TIGER) System. Census blocks nest within all other
tabulated decennial census geographic entities and are the basis for all data tabulated
for the decennial census.
The table below lists the feature and boundary types currently planned as 2020 Census
tabulation block boundaries. If you flag these features as ‘Do Not Holds’ (i.e., request
that the feature or boundary type not become a 2020 tabulation block boundary), the
Census Bureau will not accept the ‘Do Not Hold’ suggestion.

Block Area Grouping
Primary and secondary roads (MAF/TIGER Feature Class Codes (MTFCCs) S1100 and
S1200) are planned tabulation block boundaries. Other features, such as local roads,
alleys, railroads, and perennial water, may or may not qualify to be tabulation block
boundaries based on the established criteria. As a BBSP participant, you may flag these
other features as “Must Hold” or “Do Not Hold” block boundaries.
Block Boundary Suggestion Project User Supplied GIS Respondent Guide

You will determine whether a feature is a planned block boundary by the feature’s value
in the Census Block Boundary Flag (CBBFLG) field in the edge attribute table of the
Census Bureau supplied edge partnership shapefile.
A CBBFLG value of “4” indicates the feature is a planned 2020 block boundary, while a
CBBFLG value of “9” indicates the feature is ineligible as a 2020 block boundary.
A CBBFLG value of "1" indicates the feature was designated a "Must Hold" by the
participant during the initial BBSP (December 2015 - May 2016), and a CBBFLG value
of "2" indicates the feature was designated a "Do Not Hold" by the participant.
The technical details for reviewing features and assigning block boundary suggestion
flags are contained in Part 2.
Note: Appendix B: MTFCC Descriptions - Complete List, contains the list of MTFCC
values in the partnership shapefiles and their descriptions.

2. Suggested BBSP Workflow
Figure 1 depicts the suggested workflow for reviewing and updating Census Bureau data
for the BBSP. This guide outlines the activities associated with each of the workflow
process (square) boxes. You are not required to perform all the update activities shown
in the flowchart.
Work is performed at a county level and should be submitted to the Census Bureau on a
flow basis, as you complete each county. Submitting work on flow basis permits the
CRVRDO and the Census Bureau to review the files early in the process and provide
feedback as necessary. It also facilitates our file processing, and provides us with
sufficient time to clarify questions and concerns, increasing the likelihood that your
update and suggestions will be processed as intended.
Figure 1: Suggested BBSP Workflow
Block Boundary Suggestion Project User Supplied GIS Respondent Guide

2.1
RDP Liaison Delegates Work
The Census Bureau works with a State RDP nonpartisan Liaison who is designated by
the governor and legislative leadership of the state. To maintain a nonpartisan
relationship, the Census Bureau only accepts completed work from the designated State
RDP Liaison.
The State RDP Liaison may choose to delegate work to an agency, a county or counties,
or a contractor. In this document, these people are collectively referred to as designees.
Regardless of who performs the BBSP work, the file updating process is the same. The
difference is that only the State RDP Liaison may submit completed work to the Census
Bureau via the Secure Web Incoming Module (SWIM).
2.2
Obtaining Census Shapefiles
In order to submit block boundary suggestions and other geographic updates, the
Census Bureau requires participants to review and update Census Bureau-supplied
Partnership shapefiles. You should receive a DVD in your participant package that
contains the partnership shapefiles for your area. There are three ways for participants
to access the partnership shapefiles:
Download the partnership shapefiles from the DVD;
Download the shapefiles from the Geography Partnership website at:
https://www.census.gov/geo/partnerships/bas/bas_download.html; or
Download the Geography Partnership shapefiles from the Census FTP site:
ftp://ftp2.census.gov/geo/PVS.
The planned block shapefile (described in Section 2.9) is included on the DVD but is
stored separately from the Geography Partnership shapefiles and can be downloaded by
the state level from the FTP site: ftp://ftp2.census.gov/geo/PVS/bbsp/.
The partnership shapefiles are downloaded in a zip file and reflect the legal boundaries
of governments effective as of January 1, 2016. The zip file name begins with
“partnership_shapefiles_PVS_16_v2”. When unzipped, the names of the shapefiles
begin with the prefix PVS_16_v2. For example, the edges shapefile is named
PVS_16_v2_edges_ (two digit state code and three digit county code).
Note: The FTP site may contain different vintages of the Geography Partnership
shapefiles. For BBSP, make sure to use vintage 2 shapefiles that begin with the
prefix PVS_16_v2.
Shapefile Projection
If you plan to use any of your own data files for reference, we recommend that you reproject your data files to match those provided by the Census Bureau to ensure correct
alignment of the data. However, returned shapefiles may be in any projection as long as
the projection information and the *.prj file are provided. A complete partnership
shapefile data dictionary is provided in Appendix D.
All shapefiles provided by the Census Bureau are in the following unprojected
geographic based coordinate system:

If you are unsure how to project your files to match ours, see Appendix H.
2.3
Updating Census Bureau Shapefiles
Participants should use the following provided partnership shapefiles for their
submissions. We recommend making a copy of any shapefile for which you plan to
provide updates. Update the shapefile as needed and export the updates following
the guidance in Section 3 of this document.

The Census Bureau requires that the returned shapefiles have specific name attributes
and characteristics in order for us to accept them as submissions. The attribute table
layout will vary depending on which type of submission you are making and is
specifically described in Sections 2.4 through 2.11.
All participants must have the ability to edit a Census Bureau shapefile. Again, the
Census Bureau requires that participants update Census Bureau shapefiles with
changes, rather than submitting their own shapefile from a local GIS. Participants must
create a separate linear feature update layer and change polygon layers for each
updated entity type (e.g. county, MCD, place, area landmark). Please create linear
feature update layers and change polygons using only the current partnership
shapefiles. We recommend you begin any updates by:
1) Making a copy of the provided partnership shapefile that you wish to edit;
2) Making updates to the file copy as described in Sections 2.4 through 2.11;
Block Boundary Suggestion Project User Supplied GIS Respondent Guide
5
3) Exporting the updates into a ‘changes’ shapefile, following the naming
conventions as described in Section 3; and
4) Zipping and submitting the shapefiles as described in Section 3.6 and Section 4.
2.4
Linear Feature Review
All line feature updates must be submitted back to the Census Bureau by
updating the PVS_16_v2_edges_ shapefile and exporting all changes into
a participant created shapefile named bbspv17__ln_changes
(See Section 3).
Review the Census Bureau’s linear features (PVS_16_v2_edges_) layer to
determine whether there are features to be added or deleted. Attribute updates
(e.g., name, MTFCC, and address ranges) for selected features may also be updated,
as specified in Appendix A2: Linear Feature Updates Permitted.
It is important that Census Bureau data reflect the most recent linear features to ensure
that new or previously missed housing units located along these features are identified
and located. Pay particular attention to any areas that have experienced recent
population growth or construction activities, as these are the most likely to possess new
or altered linear features (e.g., new streets in subdivisions or privately maintained roads
that serve as public streets but exclude private driveways).
All linear feature updates, including linear feature extensions and block boundary
suggestion flagging (Must Holds and Do Not Holds), must be saved to the linear feature
update layer (see Sections 2.8 and 2.10). Additionally, if areal landmark or legal
boundary changes are made and use existing edges, you must update or create a linear
feature update layer (see Section 2.5 and 2.6 for additional information).
In order to submit linear feature updates, participants must create a separate linear
feature update layer (see note below for file naming conventions). We recommend that
you begin by making a copy of the PVS_16_v2_edges_ for editing and creating
updates for submission to the Census. This is also referred to as the linear feature
update layer in this document. You can then export the changes from this update layer
to create your submission file, as described in Section 3.
Note: All linear feature changes must be submitted back to the Census Bureau in a
participant created shapefile named bbspv17__ln_changes, where
is the state county code (see section 3).
To review the linear features, we suggest that you begin by symbolizing the linear
feature update layer based on the MTFCC. A description of all MTFCCs can be found in
Appendix B. The basic groupings of the MTFCCs are as follows:
Sxxxx = Roads;
Rxxxx = Railroads;
Pxxxx = Nonvisible Features;
Lxxxx = Other Linear Features; and
Hxxxx = Hydrography.
Block Boundary Suggestion Project User Supplied GIS Respondent Guide

Once the edges layer is copied and symbolized, bring in other Census provided
shapefiles (e.g., CD, SLDL, SLDU, incorporated places, etc.) and any local data layers
that may be helpful. In your review, please note the following:
1. Missing Road Features - If a road, subdivision, etc. is missing from the Census
Bureau’s edges shapefile, add the feature(s) and provide the name and MTFCC
in the attribute table. Feature name is required for any added primary or
secondary roads (MTFCC = S1100 or S1200). Feature names for local roads
(MTFCC=S1400) are encouraged. The CHNG_TYPE field also needs to be
updated to 'AL'.
2. Deleting Linear Features - If a feature in the Census Bureau’s edges layer does
not exist, flag the feature by updating the attribute table with 'DL' in the
CHNG_TYPE field. Do not actually delete the feature in the file.
3. Spatial Inaccuracies –For our purposes, a feature is considered spatially
inaccurate only if it is represented in the shapefile more than 7.6 meters from it’s
actual location or it is positionally inaccurate in relation to other features and
boundaries (e.g. a stream appears on the east side of the road, when it should
be on the west side) in a way that would affect the assignment of housing units to
legal entities, census tracts, and/or census blocks. If a feature is in the incorrect
location in the Census Bureau’s edges layer, flag the feature for deletion
(CHNG_TYPE=DL) in the attribute table, and add it as a new line
(CHNG_TYPE=AL) in the correct location.
4. Incorrect or Missing Names or MTFCCs - Correct or add the name and/or
MTFCC in the attribute table and add 'CA' in the CHNG_TYPE field.
Note: In addition to wholescale realignments, there are other updates that we will not
accept due to our representation requirements. For example if a user deletes both
lanes of an interstate and adds a single line to replace the deleted interstate, we
will not accept these changes.
Required Attributes - Each linear feature update must have the required attributes and
corresponding change type populated in the attribute table. The change type field
(CHNG_TYPE) must be populated with either ‘AL’, indicating an added line, ‘DL’,
indicating a deleted line, or ‘CA’, indicating the feature was renamed or given a different
MTFCC. In addition, the following applies:
If you add a new line and delete an existing line to make a spatial correction, add
the value in the TIGER Line ID (TLID) field of the deleted line to the TLID field of
the added line.
Provide the feature name and MTFCC code in the FULLNAME and MTFCC
fields. If you add linear features with MTFCCs of Pxxxx or Lxxxx you must
attribute the BBSP_2020 field with a ’1’ (Must Hold). You can only add these
types of features if you want them to be held as a block boundary. For more
information, refer to Section 2.10.

Address Range Updates
The Census Bureau accepts, but does not encourage, address range data as part of the
linear feature update layer. Since we have an internal update process for creating and
maintaining address ranges, we may not use your data to update our database.
However, if you do choose to submit address ranges, you must include the required
attributes and populate the corresponding change type in the attribute table.
We recommend that you only add address ranges to new features. Existing address
ranges are not shown in our outgoing shapefiles; however, address ranges can be found
in the ADDR.dbf table and can be joined to the edges shapefile through a many-to-one
join.
Each address range update must have the required attributes and corresponding
change type populated.

Area Landmark and Area Hydrography Review
All area landmark and area hydrography updates must be submitted back to the
Census Bureau in a participant created shapefile named
bbspv17__alndk_changes (See Section 3).
The Census Bureau will accept updates to area landmarks (such as state parks,
cemeteries and prisons) and area hydrography as part of the BBSP. Allowable updates
for area landmarks and hydrographic areas are:
Correcting boundaries (add or remove area);
Block Boundary Suggestion Project User Supplied GIS Respondent Guide
8
Creating a new area landmark or hydrographic area;
Removing an area landmark or hydrographic area;
Changing or adding a landmark name; and
Changing/updating the MTFCC of a landmark.
Note: If your state plans to reallocate prisoners during redistricting, you may wish to
review the existing area landmarks with MTFCCs K1235, K1236, K1237, and
K1238, which represent areas with prison populations.
In order to submit area landmark and area hydrography updates, participants must
create a separate change polygon layer for area landmarks and area hydrography. It is
recommended that you make a copy of the area landmarks shapefile
(PVS_16_v2_arealm_) for editing and then export all changes into the
bbspv17__alndk_changes file.
Note: Participants may also need to submit a participant-created shapefile named
bbspv17__ln_changes is the state county code. (See section
3).
By adding and modifying areal landmarks, you may be making edits to the linear feature
layer. If you are making other edits to the linear feature layer, you will be submitting a
linear change layer. However if you are only making changes to areal landmarks during
BBSP and during these edits you add, delete, or change the edges involved in the
boundary of an areal landmark, you are also updating the linear features layer. Please
extract the changes and submit this layer in addition to the areal landmark change layer.
If you add a new area landmark or hydrographic area, the Census Bureau will process
your submission in conjunction with other sources to add the area to the MAF/TIGER
system. Table 5 shows the MTFCCs for the types of area landmarks and hydrographic
areas that can be updated (names, boundaries, etc.).

Legal Boundary Review and Update (New for 2020)
All legal boundary updates must be submitted back to the Census Bureau in a
participant created shapefile. The shapefile name depends on the type of
geography you are updating (see Section 3). Additionally we request that you
supply a whole entity file to accompany any legal boundary updates or boundary
corrections that you make. A whole entity file is a shapefile that shows the entity
being modified in its entirety. It is not required but assists in the Census Bureau’s
research on the change or correction.
At the recommendation of many states, the Census Bureau is introducing the ability for
states to review and update legal boundaries as part of Phase 1 (BBSP and BBSPV)
and Phase 2 (VTD) of the RDP. During the initial delineation phase and the subsequent
verification phase of the BBSP, state redistricting participants may submit legal boundary
updates (annexations and deannexations) and boundary corrections for counties, MCDs,
incorporated places, and consolidated cities.
If you want to report a new county, MCD, incorporated place, or consolidated city,
or delete an existing one, please call the CRVRDO at 301-763-4039, or email
[email protected].
Note: All annexations and deannexations must be submitted back to the Census Bureau
in a participant created shapefile. Refer to Section 3.3 for a breakdown of the
change shapefiles by entity type. By performing these legal boundary updates,
you may be making edits to the linear feature layer. If you are making other edits
to the linear feature layer, you will be submitting a linear change layer. However, if
you are only making changes to legal boundaries during BBSP and during these
edits you add, delete, or change the edges involved in the boundary, you are also
updating the linear features layer. Please extract the changes and submit this
layer in addition to the appropriate legal boundary change layer.
The Census Bureau will reconcile the boundary submissions with the appropriate local
governments as part of our Boundary and Annexation Survey (BAS). Although legal
documentation (effective date, authorization type, and documentation number) is not
required for boundary updates submitted through the BBSP and BBSPV, we strongly
encourage you to submit the documentation for any legal updates to expedite our ability
to reconcile and process any legal updates reported.
You do not have to provide the legal paperwork for the Census Bureau to process the
change as a legal change; however, you do need to provide the effective date,
authorization type, and documentation number. Annexations, de-annexations,
incorporations and dis-incorporations submitted without documentation should be
submitted as boundary corrections.
It is important to note that the Census Bureau cannot guarantee we will make these
updates, as we may first have to adjudicate the updates with the official BAS contact.
Annexations and Deannexations
In order to submit an annexation or deannexation, you must create a separate change
polygon layer showing the spatial differences between the boundary represented in the
Census Bureau-provided partnership shapefile and your updated boundary. We
Block Boundary Suggestion Project User Supplied GIS Respondent Guide
11
recommend that you make a copy of the relevant entity’s partnership shapefile for
editing, and then export all the changes into the submission changes shapefile. See
Section 3 for the submission file naming requirements. The submission file must include
all required attributes and corresponding change type populated, as shown in Table 7.
The name field (NAME) in the attribute table should be populated with the name of the
geographic entity affected. The change type field (CHNG_TYPE) should indicate
whether the change is an annexation (A) or deannexation (D).
The effective date field (EFF_DATE) should be populated with the date of the ordinance,
resolution, or local law authorizing the annexation or deannexation. If available, the
authorization type field (AUTHTYPE) should be populated with the type of
documentation authorizing the change (i.e., ordinance, resolution, local law, other). The
documentation field (DOCU) should be populated with the documentation number.

Boundary Corrections
As with annexations and deannexations, you must create individual change polygons for
each boundary correction. Each boundary correction must have the required attributes
and corresponding change type. The name field (NAME) must be populated with the
name of the corrected legal entity. The change type field (CHNG_TYPE) must be
populated with a ‘B’ to indicated boundary correction. The relate field (RELATE) must be
populated with ‘IN’, indicating the corrected area is within the named legal entity, or
‘OUT’, indicating the corrected area is outside of the named legal entity.

Please review all changes to ensure that the correct boundary-to-feature relationships
are being created or maintained. The Census Bureau is aware that many governments
base their legal boundaries on cadastral (parcel-based) right-of-way mapping; however,
the Census Bureau bases maps on spatial data that is topologically integrated.
Therefore, when housing units are not affected, we suggest you snap your boundaries to
Block Boundary Suggestion Project User Supplied GIS Respondent Guide
12
nearby street centerlines (or rivers, railroads, etc.) wherever applicable. This will help
establish a more accurate population count for entities.
Boundary Correction Criteria
Because the Census Bureau uses a topologically integrated database, we cannot
process all types of boundary corrections for inclusion in MAF/TIGER. The Census
Bureau will accept, adjudicate, and process boundary corrections that spatially interact
with (abut) other legal changes (annexation, deannexation) and meet both of the
following two conditions:
The existing boundary has been digitized incorrectly or appears in the incorrect
location; and
The overall shape of the geographic entity is maintained and no feature-toboundary relationships are dissolved.
The Census Bureau will not accept boundary corrections that:
Are along county boundaries unless there is a written agreement between the
two counties that documents the correct location of the boundary;
Dissolve boundary-to-feature relationships (roads, rivers, railroads, etc.) if the
difference is less than thirty feet; or
Have a width of less than thirty feet over the entire polygon.
Note: The Census Bureau will snap any entity boundary correction to a MAF/TIGER
feature when it exists within thirty feet of that feature.
2.7
Point Landmark Review
All point landmark changes must be submitted back to the Census Bureau in a
participant created shapefile named bbspv17__plndk_changes (See
Section 3)
Point landmark review is an optional activity. Because many of the point landmarks
contained in the Census Bureau’s MAF/TIGER System originate from the Geographic
Names Information System (GNIS), the official vehicle for names used by the Federal
Government, only four point landmarks can be updated:
mountain peak/summits (C3022);
cul-de-sacs (C3061);
traffic circles (C3062); and
airports or airfields (K2451).
In order to submit point landmark updates, participants must create a separate change
point layer for point landmarks. We recommend you that you make a copy of the point
landmark shapefile (PVS_16_v2_pointlm_) for editing and then export all
changes into the bbspv17__plndk_changes file.
Each point landmark update must have the required attributes and corresponding
change type populated. When modifying or deleting an existing point landmark, preserve
the existing POINTID for the feature in the attribute table.

2010 Linear Feature Extension Review
All line feature updates must be submitted back to the Census Bureau in a
participant created shapefile named bbspv17__ln_changes (See Section
3). This is the same submission file that would contain any updates to other linear
features (adds, deletes, name changes, etc.). Refer to Section 2.4 for further
details.
During the Census 2010 RDP, BBSP participants could place a “must-hold” on an
existing feature that did not form a closed a polygon. Participants were permitted to add
a short, nonvisible line to extend the feature so that it closed the polygon and created a
block. We do not plan to continue to maintain these 2010 feature extensions for 2020
unless you tell us you want us to use them again in 2020 to create blocks. The 2010
feature extensions are included in the 2020 BBSP files for review and update.
All block boundary suggestions are contingent upon the lines intersecting to form a
closed polygon at the time the Census Bureau creates tabulation blocks. As a result, all
block boundary suggestions, when combined with other features and planned holds,
must form a closed polygon.
You are not required to review the 2010 feature extensions. However, please be aware
that if you would like a 2010 feature extension held as 2020 block boundary, you must
take an action on the feature extension.
The 2010 feature extensions can be identified by selecting all edges with
attributes of BBSPFLG = 1 and an MTFCC = P0001 in the
PVS_16_v2_edges_ shapefile.
If you choose to review the 2010 feature extensions, you may:
Hold the 2010 feature extension for 2020. The feature from which the extension
originates should also be flagged as a must-hold block boundary, along with the
extension, in order to form a closed polygon. Assign BBSP_2020 with a value of
1 and a CHNG_TYPE = CA.
Delete the 2010 feature extension. Deleting 2010 feature extensions that are not
needed for 2020 blocks will help the Census Bureau remove features from the
MAF/TIGER System that no longer serve a current data tabulation purpose. If
you determine that the 2010 feature extension should not be held as a feature
Block Boundary Suggestion Project User Supplied GIS Respondent Guide
14
extension, flag the extension with a CHNG_TYPE = DL and leave the attribute
BBSP_2020 blank.
Ignore the 2010 feature extension. Be aware that 2010 feature extensions and
the features with which they are associated may not be held as 2020 tabulation
block boundaries. If you take no action on a 2010 feature extension, the Census
Bureau will determine whether to hold the extension and the feature associated
with it as a 2020 block boundary.
All updates should be saved in the linear feature update layer
(bbspv17__ln_changes). Refer to Section 2.4 Linear Feature Review for
further details.
2.9
Block Size Review (New for 2020)
To facilitate your BBSP work, the Census Bureau created “planned” 2020 tabulation
blocks based on the 2020 planned tabulation block boundaries, and estimated the
number of housing units within each of these blocks. The block size indicator is based
on the range of the number of housing units in the planned block.
Note: Although discrete numbers have been established in order to assign each block a
size value, the actual number of housing units in a block is approximate.
Factors considered when establishing the block size categories were the criteria for
block groups (minimum housing unit count of 240 and a maximum of 1,200), and the
criteria for census tracts (minimum housing unit count of 480, optimum count of 1,600,
and a maximum count of 3,200). The block size indicator is found in the BLKSZIND field
of the bbsp_2016_block_ shapefile. Table 10 lists the block size categories
and indicator values.

Note: The planned block size shapefile was created specifically for BBSP participants
and is not included in the normal suite of partnership shapefiles. The block
shapefiles (bbsp_2016_block_) are on the provided data DVD or can be
downloaded from the following Census FTP site:
ftp://ftp2.census.gov/geo/PVS/bbsp
2.10 Block Boundary Suggestion Flagging (Must Hold and Do
Not Hold)
All block boundary suggestions are considered linear feature updates and must
be submitted back to the Census Bureau in a participant created shapefile named
bbspv17__ln_changes (See Section 3). This is the same submission file
that would contain any updates to other linear features (adds, deletes, name
changes, etc.). Refer to Section 2.4 for further details.
BBSP participants can identify features they want the Census Bureau to hold (Must
Hold) or not hold (Do Not Hold) as block boundaries.
The Census Bureau has identified features planned as 2020 tabulation block
boundaries, as reflected in the provided PVS_16_v2_edges_ shapefiles. These
features have a value of "4" in the CBBFLG field of the PVS_16_v2_edges_
shapefile. You can refer to Section 1, Planned 2020 Tabulation Block Boundaries, for the
complete feature list. Because these features are planned block boundaries, it is not
necessary for you to place a 'Must Hold' flag on them. However, you may place a 'Must
Hold' flag on a feature that is a planned 2020 block boundary to help ensure that the
feature is held if the 2020 tabulation block criteria change, or the geography itself
changes from now until the time the Census Bureau creates the 2020 tabulation blocks.
The Census Bureau has also identified features that are ineligible as 2020 block
boundaries. These features have a value of “9” in the CBBFLG field of the
PVS_16_v2_edges_ shapefile. You may place a”Must Hold”' flag on these
features, but if you do so, you should enter a justification for 'holding' in the justification
field of the edges shapefile attribute table. The Census Bureau will consider the request,
but may not honor it.
There are features with no block boundary status assigned (Null). You may assign a
‘Must Hold’ or a ‘Do Not Hold’ if you have a strong preference, but you are not required
to assign a BBSP_2020 'Must Hold' or 'Do Not Hold' flag to every feature, including
street features, in the file.
The linear feature update layer contains three BBSP attributes: The first attribute field
(BBSPFLG) indicates previously identified 'Must Holds' (BBSPFLG=1) and 'Do Not
Holds' (BBSPFLG=2) from the 2010 Census.
A second attribute field (CBBFLG) identifies all currently planned 2020 Census block
boundary lines (CBBFLG=4) and ineligible lines (CBBFLG=9). A third attribute field
(BBSP_2020) is designed to capture participant suggested 2020 Census block
boundaries.
If you participated in the initial BBSP from December 2015 – May 2016, CBBFLG may
also include:

Block Boundary Criteria
All BBSPV participant-provided 2020 Census 'Must Holds' (BBSP_2020 = 1),
combined with existing features and other planned block boundaries, must form
closed polygons.
2020 Census planned tabulation block boundaries (CBBFLG = 4), are an
indication of what we would plan to use as a 2020 Census tabulation block
boundary if they were defined today. The planned tabulation block boundaries
may change if the criteria changes, or if the feature attributes are updated
through other Census programs.
BBSPV participant provided 2020 Census 'Do Not Holds' (BBSP_2020 = 2) will
not be accepted if the line they are placed on needs to be held for other
purposes. For example, if a 'Do Not Hold' were placed on an incorporated place
boundary, the 'Do Not Hold' would not be accepted.
Note: Whenever possible you should use edges that already exist in the shapefiles to
use as Must Holds. This includes when there is a small spatial difference between
the source you are using and the partnership shapefiles. However if a new feature
is needed, please add it and flag as a Must Hold (BBSP_2020=1).
Candidates for assigning a 'Must Hold' block boundary suggestion flag are:
Newly added features;
Features that are not currently planned as block boundaries (no status assigned);
and
Features that are already planned as 2020 block boundaries but you want held
should their status change.
If the block definition criteria or feature attributes change between the time BBSPV
occurs and when the Census Bureau creates 2020 census tabulation blocks, assigning a
Block Boundary Suggestion Project User Supplied GIS Respondent Guide
17
'Must Hold' to a planned block boundary feature will increase the likelihood that the
feature will become a 2020 block boundary, despite the criteria change.
Be aware that assigning a 'Must Hold' flag to a feature that is ineligible to be a block
boundary does not ensure that the Census Bureau will honor your request but we will
reevaluate the feature’s status based on your suggestion. All 'Must Hold' block boundary
suggestions are contingent upon the lines intersecting to form a closed polygon at the
time the Census Bureau creates the 2020 tabulation blocks.
In order to assign a 'Must Hold' Flag, participants must edit the attributes of the
linear feature update layer:
To assign a ‘Must Hold’ flag on an existing feature: BBSP_2020=1,
CHNG_TYPE=CA
To assign a 'Must Hold' flag on a new feature: BBSP_2020=1, CHNG_TYPE=AL.
Adding New 2020 Feature Extensions
If you wish to hold a feature as a 2020 block boundary but the feature does not form a
closed polygon, you may add a feature extension to close the polygon. Feature
extensions must meet the following criteria:
Extensions, combined with other features and planned holds, must form a closed
polygon;
Extensions must be no longer than 300 feet (if an extension needs to be longer
than 300 feet, participants must provide justification in the JUSTIFY field of the
attribute table of the linear feature update layer);
Extensions must be a straight line originating from the end of a road feature; and
Extensions must terminate on a non-road feature, with the exception of highways
(i.e., extensions may terminate on highways – MTFCC S1100).
Digitize new 2020 feature extensions in the linear feature update layer and code
each feature with a CHNG_TYPE = AL, BBSP_2020 = 1, and MTFCC=P0001.
Assigning a 'Do Not Hold' Flag (BBSP_2020=2):
You may want to place a ‘Do Not Hold’ flag on features that are not desirable as block
boundaries. Potential candidates for assigning a 'Do Not Hold' block boundary
suggestion flag may include:
Private roads, trails, and unimproved roads;
Hydrographic features with no area, shown as a single-line feature, such as a
stream or creek; and
Any feature creating unnecessary blocks, such as highway ramps, traffic circles
shown as open circles or “lollipops” in the Census geospatial files, and similar
features.
Be aware that assignment of a 'Do Not Hold' flag to a feature that is a 2020 planned
block boundary does not ensure that the Census Bureau will honor your request, but we
will reevaluate the feature’s status based on your suggestion. You may also add a
Block Boundary Suggestion Project User Supplied GIS Respondent Guide
18
justification statement in the JUSTIFY field of the linear feature update layer attribute
table.
In order to assign a 'Do Not Hold' Flag, you must edit the linear feature update
layer:
To assign a 'Do Not Hold' on an existing feature: BBSP_2020=2,
CHNG_TYPE=CA;
To assign a Do Not Hold flag on a feature that should be deleted: BBSP_2020=2,
CHNG_TYPE=DL
2.11 Block Area Grouping Delineation (Updated for 2020)
The Block Area Grouping (BAG) layer you create must be submitted back to the
Census Bureau in a participant created shapefile named
bbspv17__BAG_changes.
During the 2020 tabulation block creation, the Census Bureau will automatically group
islands to form a single tabulation block if they have no road features and the islands fall
within a 5 kilometer radius. You may also group specific islands to suggest a single 2020
tabulation block, called a BAG.
The criteria for creating a BAG are:
BAG must consist of two or more islands;
BAG perimeter must be entirely over water;
BAGs cannot overlap; and
BAGs cannot cross the boundary of other tabulation geographies, such as
counties or incorporated places.
In order to make BAG updates, participants must create a separate BAG update layer
called bbspv17__BAG_changes. We recommend that you begin by making a
copy of the Census Bureau BAG Shapefile Layer for editing and creating updates for
submission to the Census. As described in Section 3, you can then export the changes
from this update layer to create your submission file.
The shapefile should have two text fields: BAGCE (length of 3), and MTFCC (length of
5). When creating your BAGs, provide each with a number in the BAGCE field. Start with
001 and increment by 1 for each BAG created. The MTFCC should always be G5035.
BAG delineation is optional, and probably most appropriate for states with hydrographic
areas that contain a number of islands.
Grouping selected islands to create a unique block identification is done by delineating a
polygon around the selected islands. When creating a BAG, digitize the polygon around
the set of desired islands making sure not to cross any land areas. If it crosses any other
tabulations areas, it will be split along that line as well.

2.12 Block Boundary Review
You should review all your block boundary suggestions before submitting an updated
county to the Census Bureau (if you are the designated State RDP Liaison) or to the
State Liaison (if you have been delegated by the State Liaison to perform work).
2.12.1 Performing BBSP Verification
You can identify any linear features you flagged as a “Must Hold” or “Do Not Hold” in the
initial BBSP phase, using the CBBFLG field in the attribute table of the edges
partnership shapefile. CBBFLG = 1 indicates you flagged the feature as a “Must Hold”
and CBBFLG = 2 indicates you flagged the feature as a “Do Not Hold.” “Must Holds” set
in BBSPV are indicated by a value of “1” in the BBSP_2020 field, and “Do Not Holds” set
in BBSPV are indicated by a value of “2” in the BBSP_2020 field.

2.13 Validation Check
The Census Bureau recommends that you check for any non-closed polygons prior to
submitting a county return. A non-closed polygon is a polygon where you have placed
one or more 'Must Hold' block boundary flags on features but the features, when
combined with the planned block boundaries, do not “close” to form a census block. The
Census Bureau cannot accept a suggested block boundary if non-closed polygons are
present.
2.14 Work Delegated
Any work performed on behalf of the State RDP Liaison, such as by a staff member,
county or a contractor, must be submitted to the State Liaison for review and approval.
The State RDP Liaison will submit the work to the Census Bureau if they approve the
work. If the State RDP Liaison determines that BBSP work completed by a designee
requires changes or additional work, it is the liaison’s responsibility to decide whether to
make the changes or return the project to the original delineator for further updates.
The State RDP Liaison submits completed, county-level files on flow basis to the Census
Bureau through the Bureau’s Secure Web Incoming Module (SWIM; see Section 4). Do
not hold files to submit all at once. Submit data submission files as you complete them,
especially at the beginning of the update process, so that the Census Bureau has time to
provide feedback if there are errors, omissions, or other concerns.

3. Create Data Submission Files
The Census Bureau requires that the returned shapefiles have specific attributes and
characteristics in order for us to accept them as legitimate submissions. Any changes
made to the partnership shapefiles should be extracted and saved as a change
shapefile. Below is a list of change shapefile types and specifications that should be
included in your BBSP submission, depending on the type of updates made.
All returned shapefiles and whole entity shapefiles, as well as any supporting
documentation, should be placed in a .zip file named bbspv17__return.zip
prior to submitting the return to the Census Bureau.
3.1
Submitting Linear Feature Updates/Block Boundary
Suggestions
Once you have completed all linear feature updates, export the updated edges to a
shapefile named ‘bbspv17__ln_changes where is the state and
county FIPS code.
Verify that all block boundary suggestions and feature extensions contain the
correct attributes (i.e., BBSP_2020 field populated).
Verify that any added lines contain the appropriate MTFCC code (e.g., P0001 for
an invisible legal/statistical boundary) and the CHNG_TYPE field is populated.
The submission file should include :
o All Linear Features (edges) where BBSP_2020 field is populated with:
̶
1 (‘Must Hold’); or
̶
2 (‘Do Not Hold’).
and
All Linear Features (edges) where CHNG_TYPE Field is populated with:
o AL (Add Line);
o DL (Delete Line); or
o CA (Change Attribute: for BBSP_2020, Name, MTFCC, and/or Address Range).
Additionally, the linear features change shapefile should be updated and included if
there are area landmark or legal boundary updates that include existing edges.
3.2
Submitting Area Landmarks and Area Hydrography
Updates
If any updates were completed for area landmarks or area hydrography, export the
updated records to a shapefile named ‘bbspv17__alndk_changes’. The file
should include all area landmark polygons where CHNG_TYPE Field is populated with:
B (Boundary Correction);
E (New Landmark);
G (Change Name or MTFCC); or
X (Delete).
Additionally, the linear features that were modified (added or reshaped) to make these
changes should be included in the bbspv17__ln_changes return file with the
appropriate actions:
Block Boundary Suggestion Project User Supplied GIS Respondent Guide
21
3.3
AL - if you drew a new line;
DL - if you are deleting a previous boundary of an area landmark; or
CA - if you are using existing edges to bound the area landmark and flagging ('Must
Hold'/'Do Not Hold').
Submitting Legal Boundary Updates
If you want to report a new county, MCD, incorporated place or consolidated city, or
delete an existing one, please contact the CRVRDO at 301-763-4039 or email
[email protected]. If you are reporting other legal boundary changes and/or corrections,
the Census Bureau requires that you submit a change polygon file. The total number of
layers submitted depends on what types of changes are reported.
As stated in Section 2.6, we request that you supply a whole entity file to accompany
any legal boundary updates or boundary corrections that you make to assist us in
making updates. If you made legal boundary updates, then include the following files in
your submission, as applicable to the type of legal boundary update made:
MCD Change Polygon Shapefile
The file should include all change polygons where CHNG_TYPE Field is populated with:
A (Annexation);
B (Boundary Correction); or
D (Deannexation).
Return File Name:
bbspv17__changes_cousub.shp
Whole Entity File Name (if available): bbspv17__wholeentity_cousub.shp
Incorporated Place Change Polygon Shapefile
The file should include change polygons where CHNG_TYPE Field is populated with:

Submitting Point Landmark Updates
If any updates were completed for point landmarks, select by attribute to select records
that have a value in the CHNG_TYPE field. Export the updated records to a shapefile
named ‘bbspv17__changes_plndk’.
The file should include All Point Landmarks where CHNG_TYPE Field is populated with:
E (New Point Landmark);
G (Change Attribute); or
X (Delete).
3.5
Submitting Block Area Grouping Updates
If you made updates to the block area grouping layer, then include all polygons where
MTFCC = G5035 and CHNG_TYPE Field is populated with:
B (Boundary Correction);
E (New Block Area Grouping);
X (Delete).
Export the updated records to a shapefile named:
‘bbspv17__bag_changes.shp’.
3.6
Creating .ZIP File containing All change files
All returned shapefiles and whole entity shapefiles, as well as any supporting
documentation, should be placed in a .zip file prior to submitting the return to the Census
Bureau: File Name:bbspv17__return.zip.

4. File Submission through SWIM
The Secure Web Incoming Module (SWIM) is a tool for U.S. Census Bureau partners to
send their geospatial data to a Census Bureau server. For security reasons, we cannot
accept files sent via email or through our former ftp site.
The Census Bureau provides each State Redistricting Data Program Liaison a SWIM
token to establish a personal SWIM account. Once registered, you will no longer need
the token to log into the system. You will use your SWIM account to submit updates for
all phases of the 2020 Redistricting Data Program. If you are a participant for other
Census Bureau geographic programs, you may use your SWIM account to submit files
for these other geographic programs too.
Note: For the Redistricting Data Program, including the Phase 1 BBSP, the Census
Bureau will only accept files submitted by the State RDP Liaison. If a county,
agency, or contractor performs work on behalf of the state, the files must be sent
to the State Liaison for review, approval, and submission.

A very steep or vertical slope [including bluff, crag, head,
headland, nose, palisades, precipice, promontory, rim and
rimrock].
A line defined as beginning at one location point and
ending at another, both of which are in sight.
This feature class may denote a nonvisible boundary of
either public or private lands (e.g., a park boundary) or it
may denote a Public Land Survey System or equivalent
survey line.
The line that separates either land or Inland water from
Coastal, Territorial or Great Lakes water. Where land
directly borders Coastal, Territorial or Great Lakes water,
the shoreline represents the Coastline. Where Inland
water (such as a river) flows into Coastal, Territorial or
Great Lakes water, the closure line separating the Inland
water from the other class of water represents the
Coastline.
The route used to carry or convey people or cargo back
and forth over a waterbody in a boat.
A legal/statistical boundary line that does not correspond
to a shoreline or other visible feature on the ground.
The more-or-less permanent boundary between land and
water for a water feature that exists year-round.
The boundary between land and water (when water is
present) for a water feature that does not exist yearround.
A bounding Edge that does not represent a
legal/statistical boundary, and does not correspond to a
shoreline or other visible feature on the ground. Many
such Edges bound area landmarks, while many others
separate water features from each other (e.g., where a
bay meets the ocean).
A line of fixed rails or tracks that carries mainstream
railroad traffic. Such a rail line can be a main line or spur
line, or part of a rail yard.
Mass transit rail lines (including lines for rapid transit,
monorails, streetcars, light rail, etc.) that are typically
inaccessible to mainstream railroad traffic and whose
tracks are not part of a road right-of-way.

Parking Lot Road
A special purpose rail line for climbing steep grades that
is typically inaccessible to mainstream railroad traffic.
Note that aerial tramways and streetcars (which may also
be called “trams”) are accounted for by other MTFCCs
and do not belong in R1052.
Primary roads are generally divided, limited-access
highways within the interstate highway system or under
state management, and are distinguished by the presence
of interchanges. These highways are accessible by ramps
and may include some toll highways.
Secondary roads are main arteries, usually in the U.S.
Highway, State Highway or County Highway system.
These roads have one or more lanes of traffic in each
direction, may or may not be divided, and usually have atgrade intersections with many other roads and driveways.
They often have both a local name and a route number.
Generally a paved non-arterial street, road, or byway that
usually has a single lane of traffic in each direction. Roads
in this feature class may be privately or publicly
maintained. Scenic park roads would be included in this
feature class, as would (depending on the region of the
country) some unpaved roads.
An unpaved dirt trail where a four-wheel drive vehicle is
required. These vehicular trails are found almost
exclusively in very rural areas. Minor, unpaved roads
usable by ordinary cars and trucks belong in the S1400
category.
A road that allows controlled access from adjacent roads
onto a limited access highway, often in the form of a
cloverleaf interchange. These roads are unaddressable
and do not carry a name in MAF/TIGER.
A road, usually paralleling a limited access highway, that
provides access to structures along the highway. These
roads can be named and may intersect with other roads.
A path that is used for walking, being either too narrow for
or legally restricted from vehicular traffic.
A pedestrian passageway from one level to another by a
series of steps.
A service road that does not generally have associated
addressed structures and is usually unnamed. It is located
at the rear of buildings and properties and is used for
deliveries.
A road within private property that is privately maintained
for service, extractive, or other purposes. These roads are
often unnamed.
Internal U.S. Census Bureau use.

Shapefiles in a Different Coordinate
System
Shapefiles can be created in any coordinate system. Section 2.2 described the
projection system the Census Bureau uses for our partnership shapefiles. You may want
to bring in some of your local shapefiles for reference, and re-project them to match our
files, so they align properly with each other. There are lots of free conversion utilities out
there that can reproject shapefiles from one coordinate system/datum to another using
plug in utilities. After downloading and installing one of these programs, you may have to
enable the appropriate plug-in, usually by going to the Plug-ins menu and selecting the
GIS Tools listing on that menu to enable it. A new GIS Tools menu heading should
appear on the toolbar. From that GIS Tools menu, select Vector => Reproject a
Shapefile. Select the shapefile you want to re-project, and you will get a window similar
to the example below, from which you can select your target projection and datum:
Figure 11: Example
If the shapefile you are re-projecting has a .prj projection file defining its original
projection, most conversion utilities will read that automatically. If not, you will get
another window asking you to specify the original coordinate system of the shapefile.
You can then reproject the shapefile, and create a new shapefile with “_Reprojected”
appended to the original shapefile name.
Your conversion utility will create the .prj projection file for the newly-reprojected
shapefile, which many GIS programs can read automatically, and which is useful to keep
with the shapefile to keep track of its coordinate system. If you only want to create a .prj
file for a shapefile, select GIS Tools => Vector => Assign Projection to shapefile, and
follow the procedures to select the shapefile and its original projection; the conversion
utility will create a matching .prj file to go with it.
