Big Delta, AK population, income and ZIP codes

Big Delta CDP is a very small community in Alaska, with 646 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #105 of 355 ranked by population — larger than 70% of them. The median age here is 29.7 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. 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 Big Delta CDP earn a median of $101,250 a year, 28.9% above the national figure of $78,538 and 25% above the $81,250 median for the 73 Alaska 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 0.5% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Big Delta CDP is valued at $276,400, 8.9% below the national figure and 9% below the $305,100 peer median, while median gross rent runs $1,470 a month, 4.6% above the national figure, or roughly $17,640 across a full year. A household on the local median income would put about 17.4% 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 2.7×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 62% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. 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.

A median age of 29.7 means a large student or early-career population; income medians in places like this understate household resources, since many residents are supported from outside the address. With 646 residents, a handful of survey responses moves every median on this page. Compare Big Delta CDP against its county rather than against national figures.

No figure on this page is estimated by us; each one comes straight from the published ACS tables for this area. 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.
