Washington ZIP codes — Washington County, Missouri

Washington County is a mid-size town in Missouri, with 23,483 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates. The median age here is 40.2 years against 39.1 nationally, a slightly older profile than the country as a whole. Places under 65,000 residents only appear in the five-year release, never the one-year file, so these values pool sixty months of responses and lag the current year by design.

Households in Washington County earn a median of $51,886 a year, 33.9% 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 18.2% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Washington County is valued at $118,400, 61% below the national figure, while median gross rent runs $680 a month, 51.6% below the national figure, or roughly $8,160 across a full year. A household on the local median income would put about 15.7% 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 2.3×, against roughly 3.9× nationally, so purchase prices are unusually low against local pay, the pattern in places where supply is plentiful and wage growth has been flat. 76.3% 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.
