Washington ZIP codes — Washington County, Rhode Island

Washington County is a mid-size city in Rhode Island, with 130,073 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates. The median age here is 45.3 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. At this size the Census also publishes one-year estimates; the five-year values used here are steadier and let you compare against smaller neighbours on the same basis.

Households in Washington County earn a median of $102,478 a year, 30.5% above 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 8% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Washington County is valued at $469,800, 54.8% above the national figure, while median gross rent runs $1,303 a month, 7.3% below the national figure, or roughly $15,636 across a full year. A household on the local median income would put about 15.3% 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 4.6×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 76.8% 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.
