Highest Income Counties

Counties with the highest median household income and per capita earnings.

Income levels shape nearly every aspect of county life — from school funding to healthcare access to infrastructure investment. Our income score ranks counties by median household income using Census ACS data, with higher scores indicating stronger earning potential. The top-ranking counties tend to cluster around major economic centers: the Washington D.C. metro area, Silicon Valley, New York suburbs, and energy-producing regions in Texas and North Dakota. However, high income alone doesn't guarantee quality of life — many of the highest-income counties also have high costs of living, which is why our composite score balances income against housing costs and tax burden. For job seekers and professionals, these rankings identify where earning potential is strongest, but we recommend cross-referencing with our affordability and tax rankings for a complete financial picture.
