Sunnyside, WA population, income and ZIP codes

Sunnyside city is a mid-size town in Washington, with 16,329 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #87 of 639 ranked by population — larger than 86% of them. The median age here is 27.2 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. 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 Sunnyside city earn a median of $53,350 a year, 32.1% below the national figure of $78,538 and 41% below the $90,592 median for the 393 Washington cities we cover. Household income here is measured before tax and pooled across everyone at the address, which is why it reads higher than typical individual earnings in the same area. Poverty reaches 17.4% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Sunnyside city is valued at $207,200, 31.7% below the national figure and 56% below the $468,400 peer median, while median gross rent runs $1,065 a month, 24.3% below the national figure, or roughly $12,780 across a full year. A household on the local median income would put about 24% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. The home-price-to-income ratio works out to 3.9×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 59.8% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. 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.

A median age of 27.2 means a large student or early-career population; income medians in places like this understate household resources, since many residents are supported from outside the address.
