Petersburg CDP, AK in context

How this area compares with national benchmarks.

Petersburg CDP is a small town in Alaska, with 3,346 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #34 of 355 ranked by population — larger than 90% of them. The median age here is 45.5 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 Petersburg CDP earn a median of $76,466 a year, 2.6% below the national figure of $78,538 and 6% below the $81,250 median for the 73 Alaska cities we cover. This figure covers the household, not the worker: two people on ordinary wages at one address outrank a single professional in the same table. Poverty reaches 5.8% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Petersburg CDP is valued at $298,500, 1.6% below the national figure and within a couple of points of the $305,100 peer median, while median gross rent runs $1,208 a month, 14.1% below the national figure, or roughly $14,496 across a full year. A household on the local median income would put about 19% 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 3.9×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 70.6% 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.

All values below were released by the Census for this exact geography, with no gap-filling on our side. 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.
