ZIP-count and income are separate boards among 52 reporting states and territories. Income is the unweighted mean of each ZIP's ACS 2019–2023 median household income, so a rural code counts the same as a dense metro.
A high-income state on a compact ZIP set (52 codes · 1 counties): average household income $119,055 and home value $750,886 usually track the largest city more tightly than in mosaic states. Median age sits near 32.8. Skip mega-state synthesis; jump from this profile into the top city and its primary ZIP for the street-level read.
Population concentrates hard in Washington (601,239 residents · ~100% of the state ZIP total). State-wide averages inherit that metro's weight even though unweighted ZIP means still count rural codes equally: open Washington's city page and one non-metro county before trusting any statewide income or home-value line.
Compact ZIP geography: the state page is closer to a directory than a mega-atlas. Prefer the largest city page and its primary ZIP over scanning every county, and keep the FAQ answers as the quick census totals.

Frequently Asked Questions
Is District of Columbia compact enough to browse ZIP by ZIP?
Yes – 52 codes and 1 counties put District of Columbia in compact geography. Prefer the largest city page and its primary ZIP; the roll-ups here are quick census totals, not a substitute for opening one urban and one thin-edge code.
Does District of Columbia's above-median ZIP income mean every market is expensive?
No. The unweighted ZIP mean ($119,055) still mixes dense suburbs with thinner edges, and home values average $750,886. Open the densest metro and one thin-edge county before reading affordability from the state line alone.
How much does Washington dominate District of Columbia's ZIP averages?
Washington holds about 100% of state ZIP population (601,239 residents). Statewide income and home-value lines inherit that metro's weight even though unweighted ZIP means still count rural codes equally – open Washington's city page and one non-metro county before trusting any statewide figure.
