Census 101

Census data is used for:

  • Distribution of Federal Funds
    The distribution of more than $675 billion in federal funds, grants, and support to communities are based on census data. Community Development Block Grants (CDBG), HOME Investment Partnership Program, Housing Opportunities for Persons with HIV/AIDS, the Emergency Solutions Grant, the Hamilton County WIC Program, and Child and Adult Care Food Programs are examples are federally funded programs in Cincinnati and Hamilton County.

  • Fair Representation
    The results of the Census are used to reapportion the House of Representatives, determining how many seats each state receives and where those seats are allocated.

  • Political Redistricting
    Following the Census, state officials redraw the boundaries of congressional and state legislative districts to account for population shifts.

The U.S. Census Bureau collects information for statistical purposes. All responses to the Census are safe, secure, and protected by federal law. Responses are confidential and are used only to produce statistics. . In 2018, the U.S. Census Bureau completed a Census test in Providence, Rhode Island, in preparation for the 2020 Census. Part of this included testing the U.S. Census Bureau’s ability to capture and transmit responses safely and securely. Strong precautions have been taken to keep online responses secure.
