The CQR operation gives tribal, state and local governmental units the opportunity to request that the Census Bureau review their boundaries and/or housing counts to identify errors that may have occurred while processing their 2020 Census counts.
This review helps ensure that housing and population counts are allocated to the correct 2020 Census blocks in the 50 states, District of Columbia, and Puerto Rico.
CQR can only review data collected and processed during the 2020 Census. It does not collect new data or conduct a recount. If the review process finds errors related to geographic boundaries or housing placement, housing and population counts will be corrected and the revised counts will be redistributed.
Per federal law, the Census Bureau cannot update 2020 Census results through the CQR operation — or any other operation. However, CQR can correct errors that occurred when processing information that was collected during the census and redistribute a certified, revised count to affected governmental units.
If the Census Bureau makes any corrections based on a CQR review:
The submission period for reviewing 2020 Census counts through the CQR operation ended June 30, 2023. The Special Census Program can update population estimates produced by the Census Bureau. However, it cannot review or recount 2020 Census results. Refer to the Special Census Program webpage for more information.
Governments with questions about their counts had the opportunity to request a CQR review in the following situations:
CQR does not review population counts for group quarter facilities such as nursing homes, college/university student residence halls, or correctional facilities.
The following active, functioning governmental unit types were eligible to submit a CQR case for review. See the PDF below for a comprehensive list.
January 03, 2022: Governmental units begin submitting CQR cases for review.
June 30, 2023: Deadline for governmental units to submit all documentation for a CQR case.
September 30, 2023: The Census Bureau will attempt to respond to each inquiry within 90 days of receipt and complete all case research and resolution by no later than September 30, 2023. However, due to the high number of cases submitted at the June 30, 2023 deadline, our review is taking longer than expected. In order to carefully consider all cases, the Census Bureau has extended the review period, and we will attempt to send an official notification with the decision no later than December 29, 2023.
The deadline for eligible tribal, state, and local governmental units to submit a CQR case for review was June 30, 2023. It will take several months to complete processing and to notify those who have submitted a CQR request.
The Census Bureau will be releasing a complete set of 2020 Decennial Census Notes and Errata once all CQR cases have been dispositioned and governmental units have been notified.

Completed CQR boundary cases have had their boundaries corrected and are available as a 2020 Census CQR block map (pdf). Local governmental units have received this map, and upon approval from the governmental unit, has been implemented as their official boundary as of the 2020 Census.
A Block-to-Map-Sheet relationship text file (txt.) is included to assist governmental units with locating the changed tabulation block(s) on the CQR Map sheets.
