Longbranch, WA population, income and ZIP codes

Longbranch CDP is a small town in Washington, with 4,715 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #203 of 639 ranked by population — larger than 68% of them. The median age here is 50.9 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. At this population the ACS sample is small, so the margin of error around every dollar figure below is wide — treat the numbers as a band, not a point, and expect them to move between annual releases without the place itself changing.

Households in Longbranch CDP earn a median of $92,109 a year, 17.3% above the national figure of $78,538 and within a couple of points of 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 18.4% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Longbranch CDP is valued at $382,000, 25.9% above the national figure and 18% below the $468,400 peer median, while median gross rent runs $1,474 a month, 4.8% above the national figure, or roughly $17,688 across a full year. A household on the local median income would put about 19.2% 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 4.1×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 84.9% 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.

A median age of 50.9 puts Longbranch CDP well into retirement-weighted territory, which pulls median household income down even where household wealth is high, because retirement draws are counted differently from wages. Median income runs above the national figure while poverty also runs above it — a split distribution, not a uniformly comfortable place. Averages hide that; the two numbers together do not.

Every value on this page is published directly by the Census for this area — nothing is modelled or interpolated. Small-area estimates still carry wider margins of error than state or national figures, so check the linked ACS tables before relying on them for lending, appraisal or legal work.
