OCT. 19, 2017 — The U.S. Census Bureau updated the 2010 Census Congressional District Summary File for the 115th Congress (Jan. 3, 2017 – Jan. 3, 2019). The file contains recent congressional district boundary changes for Florida, Minnesota, North Carolina and Virginia with retabulated data to reflect these changes.
This summary file contains the same subject matter content as the 2010 Census Summary File 1 — age (including single years of age), sex, race and Hispanic or Latino origin (including detailed population groups), household type, relationship, population in group quarters, whether the residence is owned or rented (tenure), and vacancy status.
The congressional district boundaries used were submitted by state officials following the legislative redistricting that occurred after the 2010 Census. The file provides data for each of the 50 states, the District of Columbia and Puerto Rico; congressional districts; and selected geographic entities within the congressional districts. Also provided are selected counties, county subdivisions, census tracts, places, American Indian and Alaska Native areas, and Hawaiian home lands. A demographic profile, quick tables and geographic comparison tables from this data set will be available soon.
The release of the 2016 American Community Survey statistics in September 2017 also provides data for the 115th Congress. Differences between the American Community Survey statistics and the 2010 Census counts could be attributed to demographic changes since 2010 (births, deaths and migration), survey methodology, data collection differences and population controls, along with other possible factors. For more information on this topic, please visit ACS and Census Table Comparison reference materials.
