Get Ready for Apportionment Data Release with New Census Bureau Tool

A new online tool from the Census Bureau will help stakeholders work with 2020 Census apportionment data once it is released this month.

The “Historical Apportionment Data Map” displays apportionment results for each census. While it currently just includes 1910 to 2010, the Bureau has said that the new apportionment data will be added to the map as soon as they become public.

The interactive map includes: Number of seats in the U.S. House of Representatives; Changes to each state’s number of seats in the U.S. House of Representatives; Population per representative for each state; Resident population of each state; Percentage change in resident population for each state; and Population density of each state. It will also have downloadable tables with source data and technical documentation, and be optimized for mobile devices.

Interested stakeholders would do well to familiarize themselves with its functionality in advance of the apportionment data release.
