DuPont city, WA in context

How this area compares with national benchmarks.

DuPont city is a mid-size town in Washington, with 9,952 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #132 of 639 ranked by population — larger than 79% of them. The median age here is 35 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 DuPont city earn a median of $114,423 a year, 45.7% above the national figure of $78,538 and 26% above 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 3.6% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in DuPont city is valued at $550,200, 81.3% above the national figure and 17% above the $468,400 peer median, while median gross rent runs $2,230 a month, 58.6% above the national figure, or roughly $26,760 across a full year. A household on the local median income would put about 23.4% 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 4.8×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 60.7% 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.
