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.
The Voting District Project has two distinct parts – initial delineation, which is
referred to as VTD, and verification, referred to as VTDV. If you are submitting
VTD boundaries as part of the 2020 Redistricting Data Program (RDP) for the
first time for a county, that is an initial delineation. During verification, the state
has the opportunity to review the boundaries they submitted to ensure the
Census Bureau processed them as expected. If further updates are needed,
the states can make those updates using the same methodology used in initial
delineation. Detailed information on submitting updates—during initial
delineation or verification-- is available in Section 2 of this document.
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
reviewing, verifying and/or 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
Voting District Project GUPS User’s Guide
Section 1. Introduction

Page 1

VTDP 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.

1.3

Document Structure

Section 1 of this document provide background information on the VTDP and
this User Guide.
Section 2 provides the specific information for reviewing VTDS during verification
and making allowable updates to voting districts, linear features, areal and
hydrographic features, and legal geographies (incorporated places, minor civil
divisions and counties) whether for initial delineation or verification.
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 verify and/or submit voting district boundaries and other geographic
updates, the Census Bureau requires participants to review and update Census
Bureau- supplied 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, 2018, and the VTD submissions provided to
the Census Bureau from January 2018 through May 2018. The zip file name
Voting District Project Participant Guide
Section 2. VTDP Workflow

Page 3

begins with “partnership_shapefiles_18v2”. When unzipped, the names of the
shapefiles begin with the prefix PVS_18_v2. For example, the edges shapefile is
named PVS_18_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_18_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 or Submitting “No
Changes”

Participants should use the following provided partnership shapefiles for their
review and, if necessary to submit updates. If you previously submitted VTD
boundaries the PVS_18_v2_vtd_ shapefile should reflect the boundaries
you provided. We may have adjusted the boundaries slightly to align them to
existing geography in MAF/TIGER. After you review the shapefile, if the
boundaries are correct and do not require any further updates, please notify us
that the county does not require any updates, by emailing us at [email protected]
with a statement indicating the county code , county name, and that no
changes are needed. No further action is required.
If after you review the VTDs you determine corrections or further updates
should be made, or if you are submitting your VTD boundaries for the first
time, we recommend making a copy of any shapefile for which you plan to
provide updates. Update the shapefile as needed and export the updates
Voting District Project Participant Guide

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

When working to review and prepare a Voting District (VTD) file for submission
Voting District Project Participant Guide
Section 2. VTDP Workflow

Page 5

to the Census Bureau, it is critical that you use and update the Census
partnership file(s), 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.

•

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 (V2): 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.

Voting District Project Participant Guide
Section 2. VTDP Workflow

Page 6

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.

o
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.

VTDs must have a MAF/TIGER Feature Class Code of G5240. This is
indicated in the MTFCC field, and identifies the geography as that of a
VTD.
•

VTDs must be submitted as vintage 90, which means that is a current
geography. (Other geographies, for example VTDs that exist in the 2000
Census would have a vintage other than 90.) This is indicated in the
VINTAGE 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.

If you submitted a VTD file during the initial delineation and upon
review in verification realize you need to make additional updates,
please follow the procedures in Section 2.4.1. If you are submitting
VTDs for a county for the first time (initial delineation submission), we
recommend two possible methods for creating a VTD submission file:
starting with your own VTD layer, described in Section 2.4.2, or starting
with a blank faces layer, described in Section 2.4.3. In all cases, you must
make sure the submission file is named properly and includes all required
attributes, as shown in Table 2.

2.4.1

Using the Census 2020 VTD layer (for VTDV)
to create your VTDV Submission

1. Symbolize the faces layer (PVS_18_v2_faces_) by VTD code (VTDST).
2. When moving faces between VTDs, do so by changing the VTDST
codes on the record of the face being moved to those 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 same
fields of the face piece being moved. Remember that you must also
submit a linear feature changes file. (See Section 2.5.)
3. Once all faces have been assigned to the appropriate VTD, dissolve
the Faces layer on the VTD code.
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.

2.4.2

Using your own VTD layer to create your VTD Submission

1. Generate internal polygon centroids for the Faces layer.
(PVS_18_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 polygon Faces layer, delete the values in the VTDST field
if values exist. They would only exist if you have already submitted VTDs
during initial delineation and are trying to resubmit the entire county’s
VTDs now.
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.

Voting District Project Participant Guide
Section 2. VTDP Workflow

Page 8

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_), delete (blank) the values in the
VTDST field if values exist. They would only exist if you have already submitted
VTDs during initial delineation.
2. Assign new VTD codes to each Face in the Faces layer 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.
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_18_v2_edges_ shapefile and exporting all
changes into a participant created shapefile named
vtd19__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
Voting District Project Participant Guide
Section 2. VTDP Workflow

Page 9

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_18_v2_edges_ for editing. Update that
shapefile and export the changes into a new file named
vtd19__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 10

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.

2.6

Area Landmark Review

All area landmark and area hydrography updates must be submitted back
to the Census Bureau in a participant created shapefile named
vtd19__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

Voting District Project Participant Guide

hydrography. It is recommended that you make a copy of the area landmarks
shapefile (PVS_18_v2_arealm_) for editing and then export all changes
into the vtd19__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 vtd19__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 15

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 16

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.

Note X= Required Field

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 17

Note: The Census Bureau will snap any entity boundary correction to a MAF/TIGER
feature when it exists within thirty feet of that feature.

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 vtd19__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 initial VTD updates, please name the shapefile
‘vtd19__complete_vtd where  is the state and county FIPS
code.
If you already submitted VTD boundaries and are submitted updates to those
boundaries as part of VTD Verification, please name the shapefile
vtdv19__complete_vtd.
All VTDs should have the following attributes filled out.
The field names should be in all CAPITAL letters.

Submitting Linear Feature Review Updates

Once you have completed all linear feature updates, export the updated edges to
a shapefile named ‘vtd19__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.

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.

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 year-round.
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.
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 at-grade 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.

The main travel route for vehicles through a paved parking area.
A path that is used for manual or small, motorized bicycles, being
either too narrow for or legally restricted from vehicular traffic.
A path that is used for horses, being either too narrow for or legally
restricted from vehicular traffic.
The unpaved area or barrier between the carriageways of a
divided road.
