Household Median Income by Zip Code (ZCTA5) — Colorado

NOTE: Gray indicates insufficient data or a suppressed estimate.

The Denver-Boulder metropolitan corridor and Douglas County suburbs stand out as the highest-income cluster in the state, with numerous zip codes exceeding $125,000 in household median income, creating a prominent yellow band in the north-central region. In contrast, the southern and southeastern portions of Colorado—particularly the San Luis Valley and areas near Trinidad—display significantly lower median incomes, often falling below $40,000, while several mountain resort communities in the central-western part of the state show moderate to high incomes despite their rural settings. The eastern plains exhibit a mixed pattern of moderate-income zip codes interspersed with gray (no data) areas, reflecting sparse population density across Colorado's agricultural regions.
