Paperwork Reduction Act Statement
A federal agency may not conduct or sponsor, nor shall a person be subject to a
penalty for failure to comply with a collection of information subject to the
requirements of the Paperwork Reduction Act (PRA) unless that collection of
information displays a current valid Office of Management and Budget (OMB)
Control Number. This collection is voluntary. The authority for conducting this
collection comes from Title 13 United States Code (U.S.C.), Sections 16, 141,
and 193.
The OMB Control Number for this information collection is 0607-0988. Public
reporting for this collection of information is estimated to be approximately 372
hours per response, including the time for reviewing instructions, completing and
reviewing the collection of information.
Comments concerning the accuracy of this burden and suggestions for reducing
the burden should be directed to:

Introduction
Background
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 2020 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 Redistricting Data Program and Recommendations for
Census 2030
1.2
Purpose
This document addresses Phase 2: Voting District Project (VTDP) of the RDP.
Through the VTDP, liaisons designated by the legislative leadership in each
state, the District of Columbia, and Puerto Rico, have the opportunity to submit
their voting district boundaries (e.g. precincts, wards), codes, and names to the
Census Bureau as well as suggest additional updates to other geographic areas
as they did in the BBSP.
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) provided by the Census Bureau, for
modifying the Census Bureau supplied shapefiles. The GUPS is the Census
Bureau’s recommended tool for geographic updates, including voting district
updates, in the VTDP. We strongly recommend that VTDP participants use
GUPS. For more information on GUPS, please contact the CRVRDO at 301-7634039 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.

Document Structure
Section 1 of this document provide background information on the VTDP and this
User Guide. Section 2 provides the specific information for making allowable
updates to voting districts, linear features, areal and hydrographic features, and
legal geographies (incorporated places, minor civil divisions and counties).
Section 3 summarizes the fields required and the naming conventions for the
submission files. Section 4 describes the procedures for submitting the files to
the Census Bureau using our Secure Web Incoming Module (SWIM).
Voting District Project GUPS User’s Guide
Section 1. Introduction
Page 2
Section 2.
VTDP Workflow
The VTDP participant is not required to perform all the update activities
permitted. Work is performed at a county level and should be submitted to the
Census Bureau on a flow basis, as each county is completed. Submitting work
on a flow basis permits the CRVRDO and the Census Bureau to review the files
early in the process and provide feedback as necessary.
2.1.
RDP Liaison
The Census Bureau works with the State Redistricting Data Program nonpartisan
Liaison, designated by the governor and legislative leadership of each state at
the beginning of the RDP. To maintain a nonpartisan relationship, the Census
Bureau only accepts completed work from the designated RDP Liaison or their
designated technical representatives.
Any work performed on behalf of the State Redistricting Data Program Liaison,
such as by a 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 VTDP
work completed by a designee requires changes or additional work, it is the State
Liaison’s responsibility to decide whether to make the changes or return the
project to their designee for further updates.
The State RDP Liaison will submit completed, county-level files on a flow basis to
the Census Bureau through the Secure Web Incoming Module (SWIM). They
should not hold files to submit all at once. Files should be submitted as each
county is completed, especially at the beginning of the update period, so that the
Census Bureau can provide feedback if there are errors, omissions, or other
concerns.
2.2.
Obtaining Census Shapefiles
In order to submit voting district boundaries and other geographic updates, the
Census Bureau requires participants to review and update Census Bureausupplied partnership shapefiles. There are two ways for participants to access
the partnership shapefiles:
•
•
Download the partnership shapefiles from the DVD provided in the participant
package;
Download the partnership shapefiles from the Census FTP site:
.
The planned block shapefiles are included on the DVD but are stored separately
from the partnership shapefiles on the Census Bureau’s FTP site. They can be
downloaded by state from the FTP site: .
The partnership shapefiles are downloaded in a zip file and reflect the legal
boundaries effective as of January 1, 2017. The zip file name begins with
Voting District Project Participant Guide
Section 2. VTDP Workflow
Page 3
“partnership_shapefiles_17v2”. When unzipped, the names of the shapefiles
begin with the prefix PVS_17_v2. For example, the edges shapefile is named
PVS_17_v2_edges_ (two digit state code and three digit county code).
Note: The FTP site may contain different vintages of the partnership shapefiles. For
VTDP, make sure to use vintage 2 (v2) shapefiles that begin with the prefix
PVS_17_v2.
2.2.1.
Shapefile Projection
If you plan to use any of your own data files for reference, we recommend that
you re-project 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.
All shapefiles provided by the Census Bureau are in the following unprojected
geographic based coordinate system:
•
•
•

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 geography or shapefile you
are updating.
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 local GIS shapefile. If participants
must add features to complete area entity updates (e.g. county, MCD, place,
area landmark), a separate linear feature update layer needs to be created.
Please create linear feature update layers and change polygons using only the
current partnership shapefiles. We recommend you create and submit your
updates following this procedure:
1) Make a copy of the provided partnership shapefile that you wish to edit.
2) Make updates to the file copy.
3) Export the updates into a ‘changes’ shapefile, following the naming conventions,
and zipping the shapefiles as described in Section 3.
4) Submit the shapefiles as described in Section 4.
2.4.
Voting District Updates
All VTD updates must be submitted back to the Census Bureau by updating
the PVS_17_v2_vtd_ shapefile and exporting all changes into a
participant created shapefile named vtd18__complete_vtd.
When working to prepare a Voting District (VTD) file for submission to the
Census Bureau, it is critical that you use and update the VTD partnership file,
and that the required fields are present and correctly attributed (see Table 2:
Required Attributes for Voting District Updates). Files submitted that do not
align with Census geography will have unpredictable outcomes or may not be
able to be applied to the Census Bureau’s MAF/TIGER database. VTD
delineations must also meet the following criteria:
•
VTDs must be contained within a single county and may not cross the census
supplied county boundaries.
Voting District Project Participant Guide
Section 2. VTDP Workflow
Page 5
•
VTD relationships with other geographies must use current Census geography.
•
If a legal boundary (i.e. incorporated place boundary) needs to be updated to
accurately reflect its spatial relationship to a VTD, please submit the boundary
corrections to the legal entities as described in Section 2.7.
•
Counties should have wall-to-wall VTD coverage.
o
•
VTDs are often, but not required to be, named.
o
•
•
We request that you code all areas, including water, to a VTD. If you do
not code each area, the Census Bureau will assign the code of “ZZZZZZ”
to the unassigned areas. This allows us to ensure we have all areas
coded to a VTD.
If a name is not supplied, the Census Bureau will use the VTD code as
the name. Names can be up to 120 characters and can include spaces,
alphanumeric, and special characters. Names will appear on Census
Bureau data and geographic products, including the P.L. 94-171 Census
Redistricting Data Summary File, when the data are released after the
2020 Census.
VTDs require a Legal and Statistical Description (LSAD). There are three LSAD
values allowed for VTDs:
o
Other (00): This is indicated when the words “Voting District” are not
associated with the name. For example, a District named “Sample” with
an LSAD of “00” would appear as “Sample.”
o
Prefix (V1): This is indicated when the words “Voting District” come before
the name. For example, a District named “Sample” with an LSAD of “V1”
would appear as “Voting District Sample.”
o
Suffix: This is indicated when the words “Voting District” come after the
name. For example, a District named “Sample” with an LSAD of “V2”
would appear as “Sample Voting District.”
VTDs must be identified as “actual” or “pseudo.” This is indicated in the VTDI
field by entering an “A” or a “P”.
o
An “actual” VTD is one that exactly matches the precincts or other
election areas in your state.
o
A “pseudo” VTD is one that does not exactly represent the voting district
spatially. For example, states may choose to identify a super voting
district composed of smaller voting districts within their VTD framework
and may wish to identify the super voting district as pseudo. This is an
appropriate approach to the submission of the VTD plans.
Voting District Project Participant Guide
Section 2. VTDP Workflow
Page 6
•
VTDs must have a functional status. This is indicated in the Funcstat field. Of the
attribute table. There are two applicable functional statuses for VTDs:
nonfunctioning, and statistical.
o
Actual VTDs are considered nonfunctioning. If the VTDI field= A, the
functional status is nonfunctioning. Enter “N” in the FUNCSTAT field.
o
Pseudo VTDs are considered statistical. If the VTDI field= P, the
functional status is statistical. Enter “S” in the FUNCSTAT field.
Note: If you have a tabular equivalency file defining which 2010 Census blocks
comprise each VTD for your entire state, please contact us at
[email protected] or 301-763-4039 for other submission options.
We recommend three possible methods for creating a VTD submission file:
starting with the Census 2010 VTD layer, starting with your own VTD layer, or
starting with a blank faces layer. Regardless of which method you use, you must
make sure the submission file is named properly and includes all required
attributes, as shown in Table 2. The three methods are described below.

* If your state has names for their VTDs, we strongly suggest that you supply the
names in the file. If your state does not have names for their VTDs, we will use
the VTD code (VTDST).
2.4.1
Using the Census 2010 VTD layer to create your VTD
Submission
1. Union the 2010 VTD layer (PVS_17_v2_vtd_) with the Faces layer
(PVS_17_v2_faces_).
2. Symbolize the faces layer by VTD code (VTDST).
3. When moving faces between VTDs, do so by changing the VTDST code on the
record of the face being moved to the VTD code of the receiving VTD. You may
need to add a new linear feature to split the face if the VTD boundary itself splits
the face. If splitting faces, change the VTDST code of the face piece being
moved. Remember that you must also submit a linear feature changes file. (See
Section 2.5.)
4. Once all faces have been assigned to the appropriate VTD, dissolve the Faces
layer on the VTD code.
Voting District Project Participant Guide
Section 2. VTDP Workflow
Page 7
5. Using the dissolved output, which should now match your required boundaries,
update/review (add if needed) all of the required fields for the VTD submission
layer. (See Table 2.)
6. Rename the file as described in Section 3.1.
2.4.2
Using your own VTD layer to create your VTD Submission
1. Generate internal polygon centroids for the Faces layer.
(PVS_17_v2_faces_) preserving the FACEID field.
2. Perform a spatial join of the newly generated centroids to your VTD layer. This
creates an output of centroids with the matching VTD codes. You may want to
export this as a new layer to make it permanent and easier to use in the next
steps.
3. In the original Faces layer, add the VTD code (VTDST) field as a new field.
4. Perform an attribute join between the centroid layer created in Step 2 and the
original Faces layer on the FACEID. Copy the VTDST codes from the centroid
layer to the Faces layer into the VTDST field you added in Step 3.
5. Symbolize the original Faces layer by VTD code. This should approximate your
VTD boundaries but may require some cleanup.
6. Review the new Faces symbolized by VTD code layer.
7. Move Faces as necessary to other VTDs by changing the VTDST code on the
record of the face being moved to the VTD code of the receiving VTD. You may
need to add a new linear feature to split the face if the VTD boundary itself splits
the face. If splitting faces, change the VTDST code of the face piece being
moved. Remember you must also submit a linear feature changes file. (See
Section 2.5.)
8. Once all faces have been assigned to the appropriate VTD, dissolve the Faces
layer on the VTD code.
9. Using the dissolved output, which should now match your required boundaries,
update/review (add if needed) all of the required fields for the VTD submission
layer. (See Table 2.)
10. Rename the file as described in Section 3.1.
2.4.3
Using Blank Faces to create your VTD Submission
1. In the Faces layer (PVS_17_v2_faces_), add the VTD code (VTDST)
field as a new field.
2. Assign VTD codes to each Face as required. You may need to add a new linear
feature to split the face if the VTD boundary itself splits the face. If splitting faces,
assign the VTDST code to the appropriate face piece. (See Section 2.5.)
3. Once all faces have been assigned to the appropriate VTD, dissolve the Faces
layer on the VTD code.
Voting District Project Participant Guide
Section 2. VTDP Workflow
Page 8
4. Using the dissolved output, which should now match your required boundaries,
update/review (add if needed) all of the required fields for the VTD submission
layer. (See Table 2.)
5. Rename the file as described in Section 3.1.
2.5.
Linear Feature Review
All linear feature updates must be submitted back to the Census Bureau by
updating the PVS_17_v2_edges_ shapefile and exporting all
changes into a participant created shapefile named
vtd18__ln_changes.
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; please
exclude private driveways).
In order to submit linear feature updates, participants must create a separate
linear feature update layer. Additionally, if VTD, area landmark, or legal boundary
changes are made and use newly digitized edges from you, you must update or
create that edge in the linear feature update layer.
To create the linear feature update layer, we recommend that you begin by
making a copy of the PVS_17_v2_edges_ for editing. Update that
shapefile and export the changes into a new file named
vtd18__ln_changes, where is the state county code. Make
sure you include the required fields in the return file as shown in Table 3.)
To review the linear features, we suggest that you begin by symbolizing the
linear feature update layer based on the MAF/TIGER Feature Class Code
(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.
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. Census provided shapefiles are described in
Appendix D. In your review, please note the following:
Voting District Project Participant Guide
Section 2. VTDP Workflow
Page 9
1. Missing Road Features - If a road, subdivision, etc. is missing from the Census
Bureau’s edges shapefile, add the feature 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. Extraneous 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. We need to
receive this feature back with the DL change type so we know to remove it from
our geographic database, MAF/TIGER.
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 its
actual location or it is positionally (topologically) 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, being certain to apply the census
attributes from the feature being “deleted” (moved), most critically the TLID. Do
not attempt to reshape an edge by moving shape points. These will not be
recognized or processed.
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. We will only
accept names on roads, railroads, and hydrographic features.
5. Nonvisible edges - parcel lines, pipelines, and power lines will only be accepted
when they are being used to define a boundary and should remain unnamed.
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. All required attributes are
shown in Table 3.

Address Range Updates
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.
The Census Bureau accepts, but does not encourage, address range data as
part of the linear feature update layer. Since we have internal update processes
and other programs for creating and maintaining address ranges, we are unlikely
to use address range data submitted through this program to update our
database.

Area Landmark Review
All area landmark and area hydrography updates must be submitted back
to the Census Bureau in a participant created shapefile named
vtd18__alndk_changes.
The Census Bureau accepts updates to area landmarks and area hydrography
as part of the VTDP.
Allowable updates include:
•
•
•
•
Boundary corrections (adding and removing area);
Creating a new area landmark or hydrographic area;
Removing an area landmark or hydrographic area; and
Changing or adding a name.
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_17_v2_arealm_) for editing and then export all changes
into the vtd18__alndk_changes file.
Note: If you are making changes to areal landmarks during VTDP 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 named vtd18__ln_changes, where
is the state county code. (See Section 2.5).
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 database. Table 4 shows the MTFCCs for the types of area
landmarks and hydrographic areas that can be updated (names, boundaries,
etc.) during VTDP.

Legal Boundary Review and Update
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 post-modification
entirety.
At the recommendation of many states, the Census Bureau is continuing to
provide the opportunity for states to review and update legal boundaries in
Phase 2 (VTDP) of the RDP.
During the initial delineation phase and the subsequent verification phase of the
VTDP, state redistricting participants may submit legal boundary updates
(annexations and deannexations) and boundary corrections for counties, MCDs,
incorporated places, and consolidated cities. The opportunity to make these legal
boundary updates and boundary corrections will not be included in the second
round of verification.
If you want to report a new county, MCD, incorporated place, or
consolidated city, or delete an existing one, please call the CRVRDO at 301763-4039, or email [email protected].
Note: All annexations, deannexations, and boundary corrections must be submitted
back to the Census Bureau in a participant created shapefile. (Refer to Section
3.4 for a description of required submission files, names, and attributes by entity
type.) If you make changes to legal boundaries during VTDP and during these
edits you add, delete, or change the edges involved in the boundary, you must
also be updating the linear features layer. Please extract the linear changes and
submit this layer in addition to the appropriate legal boundary (area) change
layer(s). Refer to Section 2.4 for more information.
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 corrections submitted
through the VTDP, we strongly encourage you to submit the documentation for
any legal updates (annexations and deannexations) to expedite our ability to
reconcile and process those changes you are reporting.
You do not have to provide the actual legal paperwork as documentation for the
Census Bureau to process the change as a legal change; however, you do need
Voting District Project Participant Guide
Section 2. VTDP Workflow
Page 14
to provide the effective date, authorization type, and documentation number.
Annexations and de-annexations 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 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 the
corresponding change type must be populated, as shown in Table 6.
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. These can be contained in the same
changes layer as the annexations and deannexations. 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
Voting District Project Participant Guide
Section 2. VTDP Workflow
Page 15
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) rightof-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 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:
•
•
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.
Voting District Project Participant Guide
Section 2. VTDP Workflow
Page 16
Note: The Census Bureau will snap any entity boundary correction to a MAF/TIGER
feature when it exists within thirty feet of that feature.

Section 3.
Create Data Submission File
The Census Bureau requires that the returned shapefiles have specific attributes
and characteristics in order to accept them as legitimate submissions. Below are
the specifications for shapefiles in your VTDP Submission.
All returned shapefiles as well as any supporting documentation should be
placed in a .ZIP file named vtd18__return.zip prior to being submitted
to the Census Bureau, where is the 2 digit state and three digit county
FIPS code.
3.1
Submitting Voting District Updates
Unlike other updated area features, we ask that you send the complete VTD
shapefile to the Census, rather than the changes.
To submit your VTD updates, please name the shapefile
‘vtd18__complete_vtd where is the state and county FIPS
code.
All VTDs should have the following attributes filled out:
VTDST
•
6 character code
VTDI
•
A (Actual)
•
P (Pseudo)
LSAD
•
00 (None)
•
V1 (Prefix)
•
V2 (Suffix)

•
N Nonfunctioning legal entity (for Actual VTDs)
•
S Statistical Entity (for Pseudo VTDs)

3.2
Submitting Linear Feature Review Updates
Once you have completed all linear feature updates, export the updated edges to
a shapefile named ‘vtd18__ln_changes where is the state
and county FIPS code. Updated edges would be those with where you have
populated the CHNG_TYPE field (as per the instructions in Section 2.5):
•
•
•
AL (Add Line)
DL (Delete Line)
CA (Change Attribute)
Additionally, the linear features change shapefile should be updated and included
if there are VTD, area landmark or legal boundary updates that include newly
added or moved edges.
3.3
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 ‘vtd18__alndk_changes’.
The file should include all area landmark polygons where the CHNG_TYPE Field
is populated with:
•
B (Boundary Correction)
•
E (New Landmark)
•
G (Change Name or MTFCC)
•
X (Delete)
Additionally, the linear features that were modified (added or reshaped) to make
these changes should be included in the vtd18__ln_changes return file
with the appropriate actions:
•
•
3.4
AL — if you drew a new line;
DL — if you are deleting a previous boundary of an area landmark
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
for each entity type you are reporting change for.
Voting District Project Participant Guide
Section 3. Create Data Submission File
Page 19
As stated in Section 2.7, we request that you supply a whole entity file, in
addition to a change 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:

File Submission through Secure Web
Incoming Module
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.
If you have submitted files for any Census Bureau geographic programs, use the
same SWIM account.
Note: For the Redistricting Data Program, including the Phase 2 VTDP, 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.
