The median income for a household in D.C. is about $73,000, but household incomes vary widely depending on the type of household you live in. The households with the highest incomes are those headed by married couples. Married people with children at home have a median household income of $161,000, and married people not living with children have a median household income of $136,000. The lowest-income households tend to be those headed by an unmarried person with children. Among these households, the median income is $36,000.
These extremes in income don’t appear to be influenced much by household size once there’s more than one person in the household; 2-, 3-, and 4-person households in the city all have median incomes between roughly $90,000 and $100,000.
The large differences in income are likely due to a number factors, like number of earners in a household; higher incomes for people farther along in their careers; and higher marriage rates for people with college degrees, who are likely to earn more money than those without a college education.
