The 2020 Census 118th Congressional District Summary File (CD118) retabulates the 2020 Census Demographic and Housing Characteristics File (DHC) tables for selected summary levels related to the 118th Congressional and 2022 State Legislative Districts. It includes detailed data tables on the following:

• Subjects: Age, sex, race, Hispanic or Latino origin, household type, family type, relationship to householder, group quarters population, housing occupancy and housing tenure.
• Geographies: Congressional districts, state legislative districts and other selected geographies.

Geographic support products and additional data are available for the 118th Congressional Districts and the 2022 State Legislative Districts on the Redistricting Data Program webpage.

All CD118 data tables are available on data.census.gov and on our FTP site.

The CD118 is a retabulation of DHC data tables for select summary levels. As with all Census Bureau data products, DHC data use disclosure avoidance methods to protect respondent confidentiality. To ensure that no one can link the published data to a specific person or household with any certainty, “statistical noise” — small, random additions or subtractions — was added to the data. The Census Bureau worked closely with the data user community to implement these protections.

The Census Bureau also released metrics to help data users understand the disclosure avoidance-related variability in the DHC. The 2020 Census is the first to be able to quantify this variability because it uses a more sophisticated approach for disclosure avoidance.
