On Feb. 28, 2024, the U.S. Census Bureau released the final, full set of errata tables for the 2020 Census Count Question Resolution (CQR) program. The CQR gave tribal, state and local governments the opportunity to ask the Census Bureau to review their boundaries or housing counts to identify errors that may have occurred while processing their 2020 Census counts. Upon review, the agency made changes to the total populations of three counties: Martin (from 5,237 to 5,247); Midland (from 169,983 to 169,974); and Reeves (from 14,748 to 14,747). As stated in the Federal Register/Vol. 86, No. 207/Friday, October 29, 2021 (Introduction): No new census information products will be created by the 2020 Census CQR and no revisions will be made to 2020 Census information products, such as the apportionment counts delivered to the President for apportionment or the 2020 Census Public Law 94-171 Redistricting Data Files and Geographic Products. The 2020 Census counts shown above in the table are the original counts from the 2020 Census Public Law 94-171 Redistricting Data Files and do not reflect the changes made due to the CQR program.
