Mill Bay CDP, AK in context

How this area compares with national benchmarks.

Mill Bay CDP is a small town in Alaska, with 3,541 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #33 of 355 ranked by population — larger than 90% of them. The median age here is 35.5 years against 39.1 nationally, a slightly younger profile than the country as a whole. 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 Mill Bay CDP earn a median of $94,359 a year, 20.1% above the national figure of $78,538 and 16% above the $81,250 median for the 73 Alaska 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 5.7% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Mill Bay CDP is valued at $430,600, 41.9% above the national figure and 41% above the $305,100 peer median, while median gross rent runs $2,777 a month, 97.5% above the national figure, or roughly $33,324 across a full year. A household on the local median income would put about 35.3% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is a stretch on median earnings. The home-price-to-income ratio works out to 4.6×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 85% 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.
