{"abstract":"By this rule, the Census Bureau (Bureau) amends and removes certain regulations governing the program for challenging the Bureau's annual population estimates (Population Estimates Challenge Program). This action will improve and streamline the regulations by clarifying that part 90 pertains to requests to challenge the Bureau's annual population estimates, properly introducing an acronym used throughout part 90, eliminating inconsequential language, and amending or removing provisions that impose undue restrictions or requirements on potential challengers. The intended effect is to create a more efficient, clear, and accessible process for governmental units to request a challenge to the Bureau's population estimates, thereby promoting accuracy and accountability.","action":"Final rule.","agencies":[{"raw_name":"DEPARTMENT OF COMMERCE","name":"Commerce Department","id":54,"url":"https://www.federalregister.gov/agencies/commerce-department","json_url":"https://www.federalregister.gov/api/v1/agencies/54","parent_id":null,"slug":"commerce-department"},{"raw_name":"Census Bureau","name":"Census Bureau","id":42,"url":"https://www.federalregister.gov/agencies/census-bureau","json_url":"https://www.federalregister.gov/api/v1/agencies/42","parent_id":54,"slug":"census-bureau"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2026/01/23/2026-01239.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"90","title":15}],"citation":"91 FR 2852","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"The rule is effective January 23, 2026.","disposition_notes":null,"docket_ids":["Docket No. 260108-0019"],"dockets":[{"supporting_documents":[],"agency_name":"USBC","documents":[{"comment_count":0,"comment_start_date":"2026-01-23","updated_at":"2026-01-23T07:56:05.428-05:00","comment_url":"https://www.regulations.gov/commenton/USBC_FRDOC_0001-0066","allow_late_comments":false,"id":"USBC_FRDOC_0001-0066","comment_end_date":null,"regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":0,"id":"USBC_FRDOC_0001","title":"Recently Posted USBC Rules and Notices."}],"document_number":"2026-01239","effective_on":"2026-01-23","end_page":2855,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2026/01/23/2026-01239.xml","html_url":"https://www.federalregister.gov/documents/2026/01/23/2026-01239/clarifying-and-streamlining-the-regulatory-procedures-for-requesting-a-challenge-to-the-census","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2026-01239?publication_date=2026-01-23","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2026-01-23/2026-01239/mods.xml","not_received_for_publication":null,"page_length":4,"page_views":{"count":240,"last_updated":"2026-07-28 16:15:03 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2026-01-23/pdf/2026-01239.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2026-01239.pdf?1769089514","publication_date":"2026-01-23","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2026/01/23/2026-01239.txt","regulation_id_number_info":{"0607-AA72":null},"regulation_id_numbers":["0607-AA72"],"regulations_dot_gov_info":{"supporting_documents":[],"comments_count":0,"agency_id":"USBC","comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=USBC_FRDOC_0001","supporting_documents_count":0,"docket_id":"USBC_FRDOC_0001","document_id":"USBC_FRDOC_0001-0066","regulation_id_number":null,"title":"Recently Posted USBC Rules and Notices.","checked_regulationsdotgov_at":"2026-01-24T16:55:04Z"},"regulations_dot_gov_url":null,"significant":null,"signing_date":null,"start_page":2852,"subtype":null,"title":"Clarifying and Streamlining the Regulatory Procedures for Requesting a Challenge to the Census Bureau's Annual Population Estimates","toc_doc":"Clarifying and Streamlining the Regulatory Procedures for Requesting a Challenge to the Census Bureau's Annual Population Estimates","toc_subject":null,"topics":["Administrative practice and procedure","Census data","Reporting and recordkeeping requirements","State and local governments","Statistics"],"type":"Rule","volume":91}
