Spanaway CDP, WA in context

How this area compares with national benchmarks.

Spanaway CDP is a small city in Washington, with 34,322 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #40 of 639 ranked by population — larger than 93% of them. The median age here is 32.5 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 Spanaway CDP earn a median of $94,028 a year, 19.7% above the national figure of $78,538 and 4% 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 9.7% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Spanaway CDP is valued at $401,000, 32.2% above the national figure and 14% below the $468,400 peer median, while median gross rent runs $1,782 a month, 26.7% above the national figure, or roughly $21,384 across a full year. A household on the local median income would put about 22.7% 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 4.3×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 72.8% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. 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.
