About Civic Data Atlas
Civic Data Atlas brings comprehensive demographic data to city council districts. Most cities only compute a district’s population and racial composition after once-a-decade redistricting. Civic Data Atlas offers a more detailed portrait of who lives in each city council district, including information on housing, income, education, health, technology, transportation, and immigration. The goal is to make local district information easier to find, understand, and use by public officials, researchers, advocates, journalists, and residents.
For states and congressional districts, detailed demographic information is readily available through official Census Bureau tools like My Congressional District and data.census.gov, as well as third-party sites like Data USA, Census Reporter, and the Congressional District Health Dashboard. That is not because local district data is unimportant; it reflects how Census data is published. The Census Bureau publishes ready-made tabulations for states, congressional districts, and state legislative districts, so profiles for those geographices can simply copy published Census tables.
The Census Bureau 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.
Who created Civic Data Atlas?
Civic Data Atlas was founded by Jack Landry. Before creating Civic Data Atlas, Jack worked on economics research at the University of Chicago and then as a lead researcher at the Jain Family Institute, where his work focused on tax policy, public benefits, and microsimulation. His experience computing city-council district statistics for policy projects helped inspire Civic Data Atlas.
