Birch Bay CDP, WA in context

How this area compares with national benchmarks.

Birch Bay CDP is a mid-size town in Washington, with 11,103 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #116 of 639 ranked by population — larger than 81% of them. The median age here is 42.1 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 Birch Bay CDP earn a median of $77,120 a year, 1.8% below the national figure of $78,538 and 15% below 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 8.6% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Birch Bay CDP is valued at $439,100, 44.7% above the national figure and 6% below the $468,400 peer median, while median gross rent runs $1,201 a month, 14.6% below the national figure, or roughly $14,412 across a full year. A household on the local median income would put about 18.7% 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 5.7×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 81.1% 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. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.
