Washington ZIP codes — Washington County, Colorado

Washington County is a small town in Colorado, with 4,839 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates. The median age here is 41.2 years against 39.1 nationally, a slightly older profile than the country as a whole. At this population the ACS sample is small, so the margin of error around every dollar figure below is wide — treat the numbers as a band, not a point, and expect them to move between annual releases without the place itself changing.

Households in Washington County earn a median of $65,164 a year, 17% below the national figure of $78,538. This figure covers the household, not the worker: two people on ordinary wages at one address outrank a single professional in the same table. Poverty reaches 7.6% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Washington County is valued at $218,300, 28% below the national figure, while median gross rent runs $991 a month, 29.5% below the national figure, or roughly $11,892 across a full year. A household on the local median income would put about 18.2% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is cheap relative to what people here earn. The home-price-to-income ratio works out to 3.4×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 71.7% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

Every value on this page is published directly by the Census for this area — nothing is modelled or interpolated. Small-area estimates still carry wider margins of error than state or national figures, so check the linked ACS tables before relying on them for lending, appraisal or legal work.
