The purpose of this system is to collect statistical information from respondents for the Decennial Census Program, which includes both the American Community Survey and the Decennial Census of Population and Housing, in order to provide key infrastructure data for the nation. The American Community Survey, the Decennial Census of Population and Housing, and pilot census records are maintained to conduct research and analysis with survey and administrative data for projects as authorized by Title 13 of the U.S.C., Sections 141 and 193 and the U.S. Census Bureau; and to undertake methodological evaluations and enhancements leading to improved data collection and quality control studies. Also, information collected by the Decennial Census of Population and Housing is used to provide official census transcripts of the results to the named person(s), their heirs, or legal representatives as authorized by Title 13 of the U.S.C., Section 8 as described in the system of records notice COMMERCE/CENSUS-6, Population Census Personal Service Records for 1910 and All Subsequent Decennial Censuses (this does not apply to the American Community Survey and pilot census records).
