Sumner city, WA in context

How this area compares with national benchmarks.

Sumner city is a mid-size town in Washington, with 10,674 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #122 of 639 ranked by population — larger than 81% of them. The median age here is 35.1 years against 39.1 nationally, a slightly younger 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 Sumner city earn a median of $98,376 a year, 25.3% above the national figure of $78,538 and 9% above the $90,592 median for the 393 Washington cities we cover. Median household income counts every pre-tax dollar arriving at an address — wages, self-employment, Social Security, pensions, interest and public assistance — for everyone living there, so multi-earner households pull the figure up even where individual pay is modest. Poverty reaches 7.1% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Sumner city is valued at $478,500, 57.7% above the national figure and within a couple of points of the $468,400 peer median, while median gross rent runs $1,886 a month, 34.1% above the national figure, or roughly $22,632 across a full year. A household on the local median income would put about 23% 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 4.9×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 49.8% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.
