About Civic Data Atlas
Civic Data Atlas brings comprehensive demographic data to local political districts.
Most cities only compute a district’s population and racial composition after once-a-decade redistricting. Civic Data Atlas offers a far more detailed portrait of who lives in a city-council district. Our mission is to use this data so that local governments can better serve their constituents.
For states and congressional districts, detailed demographic information is readily available on official census.gov websites, along with many third-party sites that make it more accessible.
However, the same info isn’t available for local government on sites besides Civic Data Atlas. That is not because there is no demand for local government information. It has to do with what Census data is released. The Census publishes ready-made tabulations for states, congressional districts, and state legislative districts, so those profiles can be built directly from published Census tabulations.
The Census does not directly publish equivalent tables for local political districts. Producing them requires collecting local district geographic boundaries, aggregating data from smaller Census geographies, and addressing imperfect boundary overlap. Our approach is detailed on the Methodology page.
