The Census Bureau published Congressional Data Books in recent decades starting with the 1960 Census where you can find population and housing data tabulated by congressional districts. There are other efforts by academic and research institutions to retroactively aggregate county-level data into congressional districts for prior decades. Current data for congressional districts are readily available from the Census Bureau in a user friendly format.
While most of the resources come from the U.S. Census Bureau there are some government agencies
that present their data by congressional districts that are included here. Also included are geographic information sources such as atlases, maps, and digital shape files. Some of the geographic information sources are available in the Geography and Map Reading Room.
