Summit CDP, WA in context

How this area compares with national benchmarks.

Summit CDP is a mid-size town in Washington, with 8,885 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #139 of 639 ranked by population — larger than 78% of them. The median age here is 42.7 years against 39.1 nationally, a slightly older 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 Summit CDP earn a median of $107,977 a year, 37.5% above the national figure of $78,538 and 19% above the $90,592 median for the 393 Washington cities we cover. The median is the midpoint household, not an average, so a handful of very high earners cannot drag it upward the way they distort a mean. Poverty reaches 7% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Summit CDP is valued at $480,000, 58.2% above the national figure and within a couple of points of the $468,400 peer median, while median gross rent runs $1,460 a month, 3.8% above the national figure, or roughly $17,520 across a full year. A household on the local median income would put about 16.2% 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 4.4×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 78.9% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.
