ZIP 99766 in context

How this area compares with national benchmarks.

ZIP 99766 is a very small community in North Slope Borough, Alaska, with 721 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #88 of 245 ranked by population — larger than 64% of them. The median age here is 25.3 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 ZIP 99766 earn a median of $81,944 a year, 4.3% above the national figure of $78,538. The median is the midpoint household, not an average, so a handful of very high earners cannot drag it upward the way they distort a mean. Poverty reaches 18.1% of residents here, above the 12.4% national rate.

The typical owner-occupied home in ZIP 99766 is valued at $184,700, 39.1% below the national figure, while median gross rent runs $1,288 a month, 8.4% below the national figure, or roughly $15,456 across a full year. A household on the local median income would put about 18.9% 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 2.3×, against roughly 3.9× nationally, so purchase prices are unusually low against local pay, the pattern in places where supply is plentiful and wage growth has been flat. 68.1% 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.

A median age of 25.3 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. 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.

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.

Reading ZIP 99766 in context

How 99766 sits inside North Slope Borough and Alaska.

ZIP 99766 is tabulated inside North Slope Borough, Alaska, one of 10 ZIP areas the Census publishes for that county and 245 across Alaska. Fewer than 2,500 people are counted here, so the ZIP behaves like a village delivery route rather than a neighbourhood. County assignment on this page follows the largest share of the ZIP's land area, which matters where a delivery route crosses a county line: mail addressed to 99766 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 99766 reports a median household income of $81,944, 6% below the $87,250 county median, and 30% above the $63,203 typical AK ZIP. Owner-occupied homes are valued at a median of $184,700, 37% above the county figure and 8% above the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at $1,288 a month, which is why it reads higher than the advertised rent on a listing for the same unit.

Alaska charges 0% statewide, and local governments overlapping 99766 may add county, city or special-district levies on top. We publish the state floor for this ZIP rather than guessing a combined figure, because ZIP boundaries and taxing-district boundaries were drawn for different purposes and do not line up.

Everything above comes from the Census Bureau American Community Survey 2019-2023 ACS 5-year estimates for this ZIP Code Tabulation Area, with sales tax rates traced to the state revenue agency. Five-year estimates pool sixty months of responses, so they are stable enough to compare 99766 with its neighbours but always trail the current year, and any value the Census suppressed for sample size is shown as unpublished rather than filled in with a model.
