BACKGROUND
The Census Bureau estimates that completing this program will take 5.2 hours on average. Send
comments regarding this burden estimate or any other aspect of this collection of information,
including suggestions for reducing this burden, to . This
collection has been approved by the Office of Management and Budget (OMB). The eight-digit OMB
approval number that appears on the introductory email/letter and on the cover page of this material
confirms this approval. If this number were not displayed, the Census Bureau could not conduct this
operation. The Census Bureau conducts this operation under the legal authority of the Title 13 U.S.
Code, Section 6.

A.

Operation Overview

In TBD 2022, the U.S. Census Bureau announced the 2020 Post-Census Group Quarters Review (2020
PCGQR) by distributing an introduction letter and flyer to the highest elected or appointed official in
eligible tribal, state, and local governmental units (GUs) in the United States, including the District of
Columbia and Puerto Rico. This operation is open for voluntary participation from June X, 2022 through
June 30, 2023.
The 2020 PCGQR provides a mechanism for GUs to request the Census Bureau review their 2020
Census population counts for group quarters facilities for a specific block. Specifically, tribal
chairpersons and the highest elected officials (or their representative) from tribal, state, and local GUs
in the 50 states, the District of Columbia, and Puerto Rico may submit a 2020 PCGQR case and
supporting documentation to request a review of their official 2020 Census population count of group
quarters. The 2020 PCGQR is focused on group quarters facilities1 population count2 for specific 2020
tabulation blocks identified by the GU.
Through this formal process, the Census Bureau reviews cases received to determine if the group
quarters population counts submitted by the GU and the documentation are valid. If the Census
Bureau makes updates, the revised counts will be provided to the Population Estimates Program for
incorporation into the base population for upcoming vintages of estimates, as the production schedule
allows.
The population estimates developed from the updated population base will also be used by the
American Community Survey (ACS) and the Puerto Rico Community Survey (PRCS) as survey controls so
that the population totals from the survey conform to the updated population estimates. The Census
Bureau will not incorporate 2020 PCGQR revisions into the 2020 Census data summary files and tables,
or re-tabulate any of the other 2020 Census data products.

Group quarters include such places as college residence halls, residential treatment centers, skilled nursing facilities, group
homes, military barracks, correctional facilities, and workers’ dormitories. For detailed descriptions of group quarters types
and codes, refer to the 2020 Census Group Quarters Definitions and Code List.
2
Population counts for census blocks or other geographic units below the state level may seem inaccurate due to disclosure
avoidance measures the Census Bureau applies to the published data. Population counts at the block level have the most
“noise” of any geographic level due to use of differential privacy to protect against data disclosure. Additional information
on both disclosure avoidance and differential privacy is available at the following .

The GQ types not included are service-based locations such as Soup Kitchens (702), Regularly
Scheduled Mobile Food Vans (704), Targeted Non-Sheltered Outdoor Locations (706) and Other
Noninstitutional Group Quarters (904).
Service-based locations do not record the number of people who show up at the location on Census
Day for service. Enumerators counted everyone who was in line for service or counted them where
they were sleeping. However, Emergency and Transitional Shelters (with Sleeping Facilities) For People
Experiencing Homelessness (701), are in scope.
Detailed definitions of each valid group quarters for the 2020 PCGQR can be found in the Appendix A2.
Group quarters population count cases must include:
•

A digital list (EXCEL spreadsheet file or PDF) that includes the corrected GQ population counts
as of April 1, 2020, and the address information for the specific GQ. This list must follow the
style from the 2020 PCGQR Response Template provided by the Census Bureau as detailed in
section 2.1.

•

Population counts to represent GQ residents who lived at the GQ on Census Day (April 1, 2020)
and is consistent with the 2020 Census Residence Criteria and Residence Situations and
additional guidance provided by the Census Bureau due to the COVID-19 pandemic.

•

Supporting documentation, as described in section D.

The GUs have the option to submit supplemental demographic data (such as name, age, race, Hispanic
origin) for the residents/clients who lived at the GQ on Census Day (April 1, 2020) and is consistent
with the 2020 Census Residence Criteria and Residence Situations and additional guidance provided by
the Census Bureau due to the COVID-19 pandemic.

D.

Supporting Documentation

The Census Bureau requires specific information from the GU before committing resources to
investigate a 2020 PCGQR case. The Census Bureau labels this specific information as supporting
documentation. In general, supporting documentation includes information or details that assist the
Census Bureau with reviewing and processing a 2020 PCGQR case. GUs should include supporting
documentation with the 2020 PCGQR case submission .zip file. The bullets below serve as a checklist
when preparing the supporting documentation for a 2020 PCGQR case submission.
Supporting documentation for a group quarters population count case includes:
•

Written correspondence from the highest elected or appointed official, or their designated
representative, that:
▪ Include a summary of the contents of the submission, i.e., report from facility or its
governing institution, letter from qualified administrator stating count and date of
count, and other reports, etc.
▪ Provide as much detail as possible about the group quarters count discrepancy to assist
the Census Bureau with its research of the GU’s case.

Discusses and certifies the accuracy and validity of the source materials used to prepare
the case by including information on the creation date/timeframe, usual use, and
maintenance cycle.
Source(s) to revise the group quarters counts must include the addresses as of April 1,
2020. More recent source material must include a way to determine the addresses that
were valid on April 1, 2020.
Confirms that the updated count information includes only group quarters addresses
that existed and were available for occupancy on April 1, 2020.
When applicable, specify additional information such as whether the group quarters are
all male or female and include supporting documentation.

Consider inclusion of documentation such as:
▪ Official reports from a Licensing Agency, Funding Agency, facility, or its governing
institution.
▪ Letter from qualified administrator stating count and date of count.
▪ Other reports.

CHAPTER 1 - INTRODUCTION TO 2020 PCGQR
This first part of the guide begins by detailing the initial step, reviewing the overall 2020 Census group
quarters population counts. Subsequent chapters in this guide details the tools and materials for use in
2020 PCGQR.
The initial step for 2020 PCGQR is to review your GU’s overall 2020 Census group quarters population
counts to determine if they align with your GU’s expectations. Table 1 provides the steps to locate the
2020 Census results using the website.

Step

Action and Result(s)
From the left margin of the page beneath Browse Filters, choose Surveys. This allows for the selection of
the proper dataset to use to conduct your search.

Step 2

In the list of surveys that appear, scroll down to select Decennial Census then select Redistricting Data
(P.L. 94-171).

Step 3

Step

Action and Result(s)
With the Redistricting Data (P.L. 94-171) survey still selected, choose the Geography filter along the left
margin of the window and click on Summary Levels.

Step 4

Choose the level of geography that matches your GU and continue to select the subsequent levels of
information until you reach the list with your GU. Select Search.
In the example below, Texas is selected in the summary level (second) column, and then rather than
scrolling through the entire list of places in Texas, the image shows “Grand” entered as a search method
in the top of the third column. This reduces the number of places to scroll through and allows for easier
selection of “Grandview city, Texas.” It is important to note that multiple selections can be made prior to
choosing Search.

Population by Major Group Quarters Type. Shown in the image below taken from the 2020 Census
State (P.L. 94-171) Redistricting Summary File Technical Documentation, includes 10 fields of
information and the total group quarters population by the major group quarters types. This Table
should be used to determine group quarters population counts for the GUs.

2020 Participant Guide (Digital/Paper)

8

Step

Action and Result(s)
The Clear all button at the top left of the menu clears all selections (geography and survey) so GUs can
begin again at Step 2 with reselecting the Survey (e.g., Decennial Census - Redistricting Data (P.L. 94171)) and then reselecting the Geography.

The total group quarters addresses can be obtained using the Address Count Listing files.
These
files are available for download from our file transfer protocol (FTP) site. The files include total housing
units (including transitory units) and total group quarters counts, by 2020 Census tabulation block.
These housing unit and group quarters counts represent final counts for the 2020 Census. Group
Quarters are not available by type (i.e. university student housing, correctional facilities, etc.)
After reviewing the official 2020 Census results using the process described above, and a GU believes
its official 2020 Census group quarters results are inaccurate, they may use information presented in
Chapter 3 (digital participants), and Chapter 4 (paper participants) of this guide to submit a 2020
PCGQR case.

CHAPTER 2 - TOOLS AND MATERIALS FOR 2020 PCGQR
This chapter discusses the preferred tools and materials available to conduct a review of the 2020
Census results and to prepare a case for digital and paper participants. Appendix A describes
additional materials available for use in 2020 PCGQR.
The 2020 PCGQR website https://www.census.gov/programs-surveys/decennialcensus/decade/2020/planning-management/evaluate/pcgqr.html provides links to all these materials.
GUs can contact the Census Bureau by phone at 1 (844) 242-1765 or by email at
if they are unable to download the materials from the
website.
The Census Bureau recommends the creation of a local directory on a local computer workstation or
perhaps on a shared network storage area (e.g., a folder named “2020 PCGQR”) to organize the 2020
PCGQR materials. Save the materials, whether downloaded from the 2020 PCGQR website or received
in another manner from the Census Bureau, in the newly created directory.

Census Geocoder

The Census Geocoder is an address look-up tool that converts your address to an approximate
coordinate (longitude/latitude) and returns information about the address range that includes the
address and the census geography for the address. The geocoder is available as a web interface and as
an API (Representational State Transfer - REST - web-based service).
The tool allows you to look-up a single address. Users can find the location of an address using the
“Find Locations” option. Also, you can find the census geographic entities for an address using the
“Find Geographies” option. The “Find Geographies” option returns the state, county, census tract, and
block for each address.
To be able to submit your case you will need to provide specific geographical information in the 2020
PCGQR Response Template such as: State and County FIPS codes, and Census Tract and Block codes.
Follow the steps in Table 4 to use the Geocoder to search for the codes related to the GQ that you will
include in the case. If you are including more than one GQ in your case, you need to follow these steps
for each of the GQs.

CHAPTER 3 – 2020 PCGQR DIGITAL PARTICIPANTS
Once your GU determines a 2020 PCGQR case is necessary and wants to participate digitally, use the
guidance in this chapter of the guide to prepare and submit your 2020 PCGQR case to the Census
Bureau. Participating digitally in 2020 PCGQR means a GU will supply digital related materials (i.e., a
2020 PCGQR Response Template to support a group quarters population count case) with their 2020
PCGQR case submission.
GUs must use the Secure Web Incoming Module (SWIM) to submit their 2020 PCGQR case.
3.1 Preparing a Digital Case
3.1.1 Preparing a Digital Case with a Group Quarters Population Count Discrepancy
As first introduced in the Case Types, section C , for the Census Bureau to successfully review and
process a digital case with a group quarters population count discrepancy, it must include the following
items:
•

A completed 2020 PCGQR Response Template. The GQ Name tab is required and must be
provided in order for your case to be considered. The Resident/Client Data tab is optional. If
you want the Census Bureau to review the demographic information for the GQ that you are
submitting in the case, please fill the Resident/Client Data tab.

•

Supporting documentation, as detailed in section D.

Bureau by email at or by phone at (844) 242-1765 to
request a registration token.
To check for the existence of an existing SWIM account, or to reset a password of an established
account, choose “Forgot your password?” on the main SWIM page and enter the email address in
question to check for the existence of an account. If SWIM locates an account, it asks the established
security question for the account, for which the answer is not case-sensitive, and sends an email to
reset the forgotten password. If SWIM does not locate an account associated with the email address, it
returns the following message, “No account registered for this email address. The email address
associated with the account is case sensitive. Try again with the proper case or go to Account
Registration to register for a SWIM account. Choosing the Account Registration link opens another
window to establish a SWIM account; however, the GU staff person must have a registration token to
proceed.
Note:

The components of both the email address and the password of SWIM accounts are case-sensitive.
Make note of the format used when establishing the SWIM account (e.g., jane@anytown.org or
Jane@anytown.org or JANE@ANYTOWN.ORG). The Census Bureau recommends use of lowercase
letters and safe retention of this information for future reference.

SWIM allows four attempts to login before it temporarily locks the account for 15 minutes. After the
lock expires, try to login again, or reset the password using the aforementioned “Forgot your
password?” link on the login page. Once reset and logged into SWIM, account holders may modify their
password and security answer by selecting “Change Security” link along the top, right side of the
window.
If login issues persist, confirm the vintage of internet browser version. SWIM runs on the two most
recent versions of each of the major internet browsers, Microsoft Internet Explorer®, Microsoft Edge®,
Google Chrome®, Mozilla Firefox®, and Apple Safari®. If the browser version is older, upgrade the
version. If problems still occur with SWIM, contact the Census Bureau by phone at (844) 242-1765. It
may be necessary to create a new SWIM account.
Access SWIM from the following website: and follow the screen
instructions to choose the operation and type of entity being reported as well as the actual entity and
file location information.
SWIM file requirements include submission of .zip file format. The .zip file may not include another .zip
file as a component and it must not be larger than 250 megabytes. Do not create separate .zip files for

CHAPTER 4 – 2020 PCGQR PAPER PARTICIPANTS
The Census Bureau understands paper participation may be the best option for certain GUs (e.g.,
smaller population and/or smaller geographic area). Once your GU determines a 2020 PCGQR case is
necessary and wants to participate using paper, use the guidance in this chapter of the guide to
prepare and submit your 2020 PCGQR case to the Census Bureau.
Using paper to participate in 2020 PCGQR means a GU will supply paper (hard copy) address-related
materials (i.e., a group quarters population count case) with their 2020 PCGQR case submission. Using
paper address materials does not prohibit a GU from submitting a case; however, additional steps are
required to prepare and submit materials. For GUs choosing paper participation, the Census Bureau
strongly encourages GUs to prepare an all-paper submission to simplify the process by not creating a
mixed media submission.
4.1 Preparing a Paper Case with a Group Quarters Population Count Discrepancy
As first introduced in the Case Type, section C, for the Census Bureau to successfully review and
process a paper case with a group quarters population count discrepancy, it must include the following
items:
•

A completed 2020 PCGQR Response Template. GQ Name tab is required and must be provided
in order to consider your case. Resident/Client Data tab is optional. If you want the Census
Bureau to review the demographic information for the GQ that you are submitting in the case,
please complete the Resident/Client Data tab.
o For a paper submission you must print ALL the correspondent pages, from both the GQ
Name tab and the Resident/Client Data tab (if appropriate). Please identify each page
with the Entity Name and ID.
o You may complete the 2020 PCGQR Response Template by filling in the printed pages or
by completing the template digitally and then printing all of the pages.

•

Supporting documentation, as detailed in section D.

•

Any additional documentation that you understand could help the Census Bureau to review
your case (e.g., summary demographic information about residents of a GQ).

For those planning to handwrite the corrected count information:
1. Print the pages that contain the group quarters population discrepant counts identified.
2. Handwrite the correct group quarters population count for the group quarters identified with
discrepant counts into the respective fields.
3. Prepare and assemble the supporting documentation following guidance in section D.
4. Stage the handwritten pages and supporting documentation for quality checks and assemble
as described in section 4.2.
When preparing the paper submission please use either blue or black ink (DO NOT USE PENCIL), ensure
your handwriting is legible, and number the pages.

4.2 Conducting Quality Checks and Finalizing a Paper Submission
After completing the process of updating the group quarters counts perform quality checks on the
page(s). The quality checks vary based upon the type of case. Assemble the completed paper materials
or navigate to the local directory where the paper case materials are saved (e.g., 2020 PCGQR). You
must still use the Geocoder (Section 2.2) to fill out the 2020 PCGQR Response Template.
4.2.1 Quality Checks for a Paper Case with a Group Quarters Population Count
•

Ensure to only include qualifying group quarters (i.e., that existed and were available for
occupancy on April 1, 2020).

•

Ensure the inclusion of all supporting documentation as described in section D.

•

Ensure to include the information for all the required fields.

4.2.2 Finalizing a Paper Submission
Once satisfied with the content and quality of the 2020 PCGQR case materials, proceed with assembly
and packaging following the guidance below. Retain a copy for your records and to facilitate
communication with the Census Bureau if questions arise.
1. Locate the staged materials.
2. Double wrap the hard copy materials using an inner and outer envelope (or container); one
within the other.
3. Label both sides of the inner envelope/container with the notice,
“DISCLOSURE PROHIBITED BY TITLE 13 U.S.C.”
4. Place the inner envelope/container into the outer envelope/container.
5. Include all relevant, hard copy supporting documentation.
4.3 Submitting a Paper Case
After completing the assembly of materials, paper participants should ship their 2020 PCGQR case to
the Census Bureau’s National Processing Center. The Census Bureau recommends using a service that
provides tracking information, such as the United States Postal Service (USPS) traceable delivery,
FedEx, United Parcel Service (UPS), or similar service. Retain the tracking information as proof of
delivery.
Ship the 2020 PCGQR case submission to the following address:
U.S. Census Bureau

NEXT STEPS FOR 2020 PCGQR
The Census Bureau will respond to all cases, even if the case is considered ineligible for 2020 PCGQR
and notify the affected governmental units of any updates resulting from a 2020 PCGQR decision in the
form of an official determination letter.

If the Census Bureau makes updates, the revised group quarters population counts will be provided to
the Population Estimates Program for incorporation into the base population for upcoming vintages of
estimates, as the production schedule allows. The population estimates developed from the updated
population base will also be used by the ACS and the PRCS as survey controls so that the population
totals from the survey conform to the updated population estimates. The Census Bureau will not
incorporate 2020 PCGQR revisions into the 2020 Census data summary files and tables, or re-tabulate
any of the other 2020 Census data products.

These materials, as directed by Public Law (P.L.) 94-171, were the first materials released by the Census
Bureau, other than Apportionment, with the 2020 Census results. They include data files and
geographic products (e.g., maps, block equivalency files, and shapefiles), that the 50 states, District of
Columbia, and Puerto Rico use for legislative redistricting.
The redistricting data files contain block level 2020 Census results that include people and housing
characteristics for specific geographic areas. GUs may review Table P1 – Race to determine if their
overall, total population aligns with their expectations. If not, GUs may review Table H1 – Occupancy
Status and P5 – Group Quarters Population by Major Group Quarters Type in their state’s data file.
The universe table for Table P5 – Group Quarters Population by Major Group Quarters Type is
population in group quarters. Table P5 contains the total population living in group quarters. This
count is further disaggregated into institutionalized and noninstitutionalized group quarters population
counts. Table P5 does not contain demographic characteristics.
