ZIP 99558 in context
How this area compares with national benchmarks.
ZIP 99558 is a very small community in Yukon-Koyukuk Census Area, Alaska, with 85 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #196 of 245 ranked by population — larger than 20% of them. The median age here is 24.3 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 99558 earn a median of $64,028 a year, 18.5% below the national figure of $78,538. 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 12.9% of residents here, above the 12.4% national rate.
The typical owner-occupied home in ZIP 99558 is valued at not published, while median gross rent runs not published a month. 38.6% of occupied homes are owner-occupied versus 65% nationally, a renter-majority market, so rent figures matter more here than the home-value line. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.
A median age of 24.3 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. With 85 residents, a handful of survey responses moves every median on this page. Compare ZIP 99558 against its county rather than against national figures.
The Census withheld home value, gross rent for ZIP 99558 because the sample was too thin to publish at this geography. Those values were suppressed at the source, not lost in our dataset, and we do not model a replacement. Everything else on this page comes straight from the ACS 2019-2023 ACS 5-year tables.

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 99558 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.
