Sources
Data comes from the U.S. Census Bureau, specifically the American Community Survey .
This map uses the S0101_C01_001E dataitem from the ACSST5Y2021.S0101 dataset.
The map templates were adapted from an early version of USA Counties.svg available on Wikimedia Commons.
Modifications have been made to account for boundary and name changes over time (especially in Alaska) based on data available on the US Census Bureau’s Cartographic Boundary Files, with the help of the excellent Mapshaper tool.
Changes to US counties since 1970 are available on the US Census Bureau’s Technical Documentation pages.
