Adak, AK

ZIP code 99546 is assigned to Adak, AK, and falls within Aleutians West (CA) County. Like every US postal code, it began as a mail-routing device rather than a geographic boundary — the US Postal Service groups delivery routes under a single code so carriers and sorting equipment can process mail efficiently. Today it also serves as a practical shorthand for the area itself: roughly 141 people live inside it.

At 4 residents per square mile spread over 32.434 square miles, 99546 reads as a rural area. It is a sparsely populated postal code, and density shapes almost everything else on this page — how people get to work, whether they own or rent, and what housing costs.

Household earnings run below the national median. At $50,000, 99546 sits in the lower half, ahead of 16% of them. The US median for comparison is $70,109. Bear in mind that median income describes the midpoint household, not the average — it is not pulled upward by a handful of very high earners the way a mean would be.

Housing in 99546 costs well below the national median. A typical home is valued at $78,000 against a US median of $207,500. This is firmly renter territory — 85.1% of occupied homes are rented, a pattern typical of city centres, student areas and neighbourhoods with a lot of apartment stock.

The building stock is dominated by small multi-family buildings of two to four units, which account for 89.9% of housing units here. The median construction year is 1983, making the housing here from the later twentieth century. The vacancy rate of 66.1% is high, which in many places reflects seasonal or second-home use rather than abandonment.

The population skews considerably older than the national median, with a median age of 53.6 against 42 nationally. Households average just 1.5 people, and 61.7% consist of one person living alone — a signature of areas with a lot of studio and one-bedroom stock.

Getting to work takes 5.0 minutes on average one way. The dominant mode is drove alone at 59.8% of workers, while 18.8% walk. Commute patterns are one of the better proxies for how a place actually functions day to day.

Beyond addressing mail, 99546 does a lot of quiet administrative work. Retailers use it to calculate shipping and sales tax at checkout. Insurers use it to set premiums, since risk profiles vary geographically. Employers and marketers use it to define service areas. Government agencies use it to route benefits and organise reporting. If you have ever been asked for a postal code by a form that clearly does not intend to send you anything, this is why.

For anyone weighing a move, 99546 offers a compact profile of Adak: 141 residents, a median household income of $50,000, 9.2% of adults holding a bachelor's degree or higher, and an unemployment rate of 4.3%. A handful of figures like these answer more relocation questions than most neighbourhood guides do.

One caution worth repeating: a postal code is not a neighbourhood. 99546 may cover parts of several distinct areas, and a single neighbourhood in Adak may be split across more than one code. Boundaries also shift as USPS adjusts delivery routes. Treat the figures here as describing a delivery area, which is what they actually measure.
