Median Household Income Estimates by County: 1989   to 2015 and Projection for 2016

This table contains estimates of median household income by county in current dollars; series revised 1990 forward. The estimation relies on both 1990 and 2000 census data. These estimates are based on past relationships between available socioeconomic data and county-level median household income. The estimates shown may differ from other median household income data developed from the Office of Financial Management's State Population Survey, Bureau of the Census surveys, or other sources. Survey data, which are subject to sampling variability and bias, are not necessarily more accurate than the estimate data. For small counties, the estimated series may show large variations during certain periods.
