On June 12, 2013, HUD published a Federal Register document that established the Native American Housing and Self-Determination Formula Negotiated Rulemaking Committee, 2013 (Committee). The purpose of the Committee is to developregulatory changes to the funding formula for the Indian Housing Block Grant (IHBG) program authorized by the Native American Housing Assistance and Self-Determination Act of 1996. As part of its charter, the Committee is reviewing whether the current data source for the needs variables, which is the U.S. Decennial Census, should be updated or revised. HUD and the Committee are considering all relevant data sources, including the American Community Survey (ACS), and how each data source might be used or modified, to serve as the source of the data upon which the needs variables of the IHBG formula would be based. This Request for Information requests interested members of the public to provide information regarding alternate data sources, including ACS, which might serve as the basis upon which the needs variables of the IHBG formula could be based.
