District of Columbia ZIP Codes

District of Columbia (DC) contains 52 ZIP codes spread across 1 counties and 2 distinct cities. Together those ZIP areas cover a total population of 601,370 based on Census ACS 5-Year Estimates. ZIP-level granularity matters here: District of Columbia stretches across very different economic zones, and a single state-wide average hides the 10x spread you will see between its highest-income and lowest-income ZIP codes in the table below.

The economic baseline across District of Columbia ZIPs shows an average median household income of $119,055 and an average home value of $750,886, with a state-wide average median age of 32.8. These averages are computed over every ZIP in DC with reported data, not weighted by population, so small rural ZIPs count the same as metropolitan ones. Use them as a reference line, then drill into the ZIP tables to see where affluent suburbs, rural counties, and urban cores deviate from the state mean.

The largest urban concentrations in District of Columbia by population are Washington, Naval Anacost Annex, and each city aggregates multiple ZIP codes worth of Census data on its own city page. Every record in this view comes from publicly available federal datasets, primarily the U.S. Census Bureau American Community Survey and USPS ZIP Code Tabulation Area files, with no proprietary scoring, estimation, or editorial adjustment.
