Rochester, WA population, income and ZIP codes

Rochester CDP is a mid-size town in Washington, with 6,025 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #176 of 639 ranked by population — larger than 72% of them. The median age here is 43.3 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 Rochester CDP earn a median of $94,754 a year, 20.6% above the national figure of $78,538 and 5% above the $90,592 median for the 393 Washington cities we cover. The median is the midpoint household, not an average, so a handful of very high earners cannot drag it upward the way they distort a mean. Poverty reaches 14.8% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Rochester CDP is valued at $391,600, 29.1% above the national figure and 16% below the $468,400 peer median, while median gross rent runs $1,182 a month, 15.9% below the national figure, or roughly $14,184 across a full year. A household on the local median income would put about 15% 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 4.1×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 86.5% of occupied homes are owner-occupied versus 65% nationally, an owner-dominated market where rental listings are scarce and rent medians rest on a thin sample. Rent is reported gross — contract rent plus tenant-paid utilities — which is why it runs above the advertised price on a listing for the same unit.

Median income runs above the national figure while poverty also runs above it — a split distribution, not a uniformly comfortable place. Averages hide that; the two numbers together do not.

All values below were released by the Census for this exact geography, with no gap-filling on our side. 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.
