How this is ranked

Median household income from the Census Bureau's American Community Survey 5-year estimates (2020–24). Survey estimates carry margins of error, so counties a few hundred dollars apart may not really differ. Counties with fewer than 1,000 residents, or without a figure for the same period as the others, are not ranked.
