Maple Valley city, WA in context

How this area compares with national benchmarks.

Maple Valley city is a small city in Washington, with 28,121 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #46 of 639 ranked by population — larger than 92% of them. The median age here is 36.5 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 Maple Valley city earn a median of $147,546 a year, 87.9% above the national figure of $78,538 and 63% 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 5.1% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Maple Valley city is valued at $672,000, 121.5% above the national figure and 43% above the $468,400 peer median, while median gross rent runs $2,189 a month, 55.7% above the national figure, or roughly $26,268 across a full year. A household on the local median income would put about 17.8% 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. 84.4% 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. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.
