Loudoun County again led the nation in 2017 in median household income at nearly $136,000, according to the U.S. Census Bureau. That mark is more than double the national average of $61,300 in 2017.
Loudoun first found itself atop the household income category in 2007, when the median income was just over $107,000.
The county's economic development office notes “median income is an important economic indicator because it indicates the buying power of a county’s residents. It is favored over the average incomes because it is less susceptible to skewing by outliers.”
After Loudoun County Public Schools and the county government, Loudoun's leading employers are Verizon, United Airlines, the Department of Homeland Security and Raytheon.
Economic development officials attribute part of Loudoun’s high income levels to the highly educated population and low unemployment rates.
Nearly 60 percent of the county's residents have a bachelor's degree, and the unemployment rate was 2.3 percent in October.
