ZIP 99901 in context

How this area compares with national benchmarks.

ZIP 99901 is a mid-size town in Ketchikan Gateway Borough, Alaska, with 13,875 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #19 of 245 ranked by population — larger than 92% of them. The median age here is 40.8 years against 39.1 nationally, a slightly older profile than the country as a whole. Places under 65,000 residents only appear in the five-year release, never the one-year file, so these values pool sixty months of responses and lag the current year by design.

Households in ZIP 99901 earn a median of $89,155 a year, 13.5% above the national figure of $78,538. 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 9.5% of residents here, below the 12.4% national rate.

The typical owner-occupied home in ZIP 99901 is valued at $379,000, 24.9% above the national figure, while median gross rent runs $1,388 a month, 1.3% below the national figure, or roughly $16,656 across a full year. A household on the local median income would put about 18.7% 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 4.3×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 67.3% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

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.

Reading ZIP 99901 in context

How 99901 sits inside Ketchikan Gateway Borough and Alaska.

ZIP 99901 is tabulated inside Ketchikan Gateway Borough, Alaska, one of 1 ZIP areas the Census publishes for that county and 245 across Alaska. This is a mid-sized ZIP that covers a large share of its county's addresses. 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 99901 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 99901 reports a median household income of $89,155, close to the $89,155 county median, and 41% above the $63,203 typical AK ZIP. Owner-occupied homes are valued at a median of $379,000, close to the county figure and 122% above the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at $1,388 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 99901 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 99901 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.
