2020 Post-Census Group Quarters Review (PCGQR)

OMB Control No. 0607-xxxx

B. Collections of Information Employing Statistical Methods

There are no statistical methods involved in the collection of this information.

1. Describe (including a numerical estimate) the potential respondent universe and any sampling or other respondent selection method to be used. Data on the number of entities (e.g., establishments, State and local government units, households, or persons) in the universe covered by the collection and in the corresponding sample are to be provided in tabular form for the universe as a whole and for each of the strata in the proposed sample. Indicate expected response rates for the collection as a whole. If the collection had been conducted previously, include the actual response rate achieved during the last collection.

Though the universe of eligible governmental units for the 2020 PCGQR is approximately 40,000, the Census Bureau estimates the number of respondents to be 1,500. The Census Bureau estimates the time to respond is 5.2 hours.

2. Describe the procedures for the collection of information including:

   • Statistical methodology for stratification and sample selection is not applicable.

   • Estimation procedure is not applicable.

   • Degree of accuracy needed for the purpose described in the justification is not applicable.

   • Unusual problems requiring specialized sampling procedures is not applicable.

   • Any use of periodic (less frequent than annual) data collection cycles to reduce burden is not applicable.

The Census Bureau announces the 2020 PCGQR by sending an email or letter to all eligible governmental units. This initial communication includes the operational timeframe, an informational flyer, and the 2020 PCGQR website address. The 2020 PCGQR website is the platform for dissemination of operational materials and instructions. Upon request, the Census Bureau can mail materials to participants unable to utilize the internet.

The Census Bureau collects information for the 2020 PCGQR operation electronically by using the internet as a means for participants to send their cases. Procedures for using the Census Bureau’s Secure Web Incoming Module (SWIM) are in the participant guides.

For all participants that submit a case, the Census Bureau provides feedback regarding their findings in the form of letters that are distributed by email or hard copy. Telephone and email communication may occur as the Census Bureau processes a participant’s case. The operation closes on June 30, 2023, without additional communication.

3. Describe methods to maximize response rates and to deal with issues of non-response. The accuracy and reliability of information collected must be shown to be adequate for intended uses. For collections based on sampling, a special justification must be provided for any collection that will not yield "reliable" data that can be generalized to the universe studied.

The 2020 PCGQR is a voluntary review with no requirement to participate. The Census Bureau distributes an introductory email (or letter by United States Postal Service if an email address is not available for the governmental unit) and a flyer in May 2022 to all eligible governmental units about the operation and its timeframe (June 2022 – June 30, 2023). This introductory communication includes instructions to download materials from the 2020 PCGQR website should the governmental unit decide to participate. No follow-up communication will be distributed to request participation.

The 2020 PCGQR provides a mechanism for tribal, state, and local governmental units in the United States and Puerto Rico, or their designated representatives, to submit a request to the Census Bureau to review their population counts for group quarter facilities by block to correct error(s) affecting the inclusion of group quarters and their population from the 2020 Census. The Census Bureau will conduct 2020 PCGQR case research by examining the 2020 Census records for the 2020 tabulation block(s) identified in the 2020 PCGQR case. All population counts are current as of April 1, 2020. Revised group quarters population counts will be provided to the Population Estimates Program for incorporation into the base population for upcoming vintages of estimates. Updated data will be included in the next population base as the production schedule allows. Similarly, updates to total group quarters population counts may be incorporated along with corresponding changes to demographic characteristics. The estimates developed from the updated population base will also be used by the American Community Survey and the Puerto Rico Community Survey. No new 2020 Census information products will be created by the 2020 PCGQR. This includes no revisions to 2020 Census information products such as the counts delivered to the President for apportionment or the 2020 Census Public Law 94-171 Redistricting Data Files and Geographic Products.

4. Describe any tests of procedures or methods to be undertaken. Testing is encouraged as an effective means of refining collections of information to minimize burden and improve utility. Tests must be approved if they call for answers to identical questions from 10 or more respondents. A proposed test or set of tests may be submitted for approval separately or in combination with the main collection of information.

The Census Bureau will not conduct a test phase or test sampling for 2020 PCGQR.

5. Provide the name and telephone number of individuals consulted on statistical aspects of the design and the name of the agency unit, contractor(s), grantee(s), or other person(s) who will actually collect and/or analyze the information for the agency.

There are no statistical aspects of the operation. However, several individuals provided comments during the review period for the 60-day Federal Register Notice related to the design of the operation. Those individuals, their questions, and the Census Bureau’s answers to those questions are documented in Question 8 of the Supporting Statement Part A.

For a contact within the agency, please note the 2020 PCGQR is managed by the Census Bureau’s Coverage and Evaluations Branch within the Decennial Census Management Division. The operational point of contact is Sonia G. Collazo, Chief of the Coverage and Evaluations Branch. She can be reached by email at Sonia.G.Collazo@census.gov by phone at 301-763-3350.
