About this ranking

Household income at the middle of the distribution for one year, in US dollars of that year. United States: Census Bureau Small Area Income and Poverty Estimates (SAIPE) for the nation, states and counties.

A model-based estimate that combines the one-year American Community Survey with federal tax records and other administrative data, so every county gets a figure for a single year. The national figure is the one-year ACS estimate. Not adjusted for inflation between years. The Census Bureau advises comparing years from 2006 on only. For the five-year ACS median, which also covers cities, use median_household_income.

Every value in the ranking comes from the same publisher and the same period, so the counties are compared on one definition. Equal values share a rank.
