Fresh.Data current as of Apr 24, 2026
Utqiaġvik, AK (ZIP 99723) sits in North Slope Borough. The page draws on 2 federal data feeds retrieved Apr 27. Top health signal: Annual Checkup comes in above the national average at 64.8%. NCES lists 5 schools serving the area, 5 non-charter. 2 colleges and universities serve the area, with median in-state tuition of $6,998. Average annual pay across local establishments runs $150,493 per worker (Census ZBP) — a high-wage local economy. BLS QCEW puts average annual pay at $128,567 per worker — about 96% above the US average and a clear high-wage signal. FDIC counts just 1 bank branch in this ZIP (Summary of Deposits, 2024) — residents likely lean on neighboring ZIPs or online banking for most services. CDC's Social Vulnerability Index places this ZIP in the 95th percentile nationally — a highly vulnerable community profile. Severe Storm accounts for 50% of the 8 FEMA disaster declarations on record for this ZIP. Annual average temperature is just 13.7°F per NOAA's 1991–2020 Climate Normals — a notably cold-weather climate. Median daily AQI is just 5 per EPA AQS (2024), comfortably inside the Good range, with PM2.5 as the primary pollutant on most measured days. 37.9% of residents in this county are flagged low-access by USDA's 2025 Food Environment Atlas — a notable supermarket-access gap. Alaska has no state income tax (Tax Foundation 2025). IRS migration data (2022-2023) shows a net loss of 229 residents (107 households) — the ZIP's primary county is shrinking. Healthcare access is the area's quieter strength; school options sit on the lighter side, so families may find themselves looking at districts a few ZIPs over. Notable: median household income $86,810, fair market rent of $1,680 for a two-bedroom, and a typical home value of $310,407, up 2.8% over the past year. Every figure on this page links to its underlying federal dataset with a retrieval date so you can audit the freshness yourself.

What these numbers say together
Utqiaġvik, AK (ZIP 99723) sits in North Slope Borough. The page draws on 2 federal data feeds retrieved Apr 27. Top health signal: Annual Checkup comes in above the national average at 64.8%. NCES lists 5 schools serving the area, 5 non-charter. 2 colleges and universities serve the area, with median in-state tuition of $6,998. Average annual pay across local establishments runs $150,493 per worker (Census ZBP) — a high-wage local economy. BLS QCEW puts average annual pay at $128,567 per worker — about 96% above the US average and a clear high-wage signal. FDIC counts just 1 bank branch in this ZIP (Summary of Deposits, 2024) — residents likely lean on neighboring ZIPs or online banking for most services. CDC's Social Vulnerability Index places this ZIP in the 95th percentile nationally — a highly vulnerable community profile. Severe Storm accounts for 50% of the 8 FEMA disaster declarations on record for this ZIP. Annual average temperature is just 13.7°F per NOAA's 1991–2020 Climate Normals — a notably cold-weather climate. Median daily AQI is just 5 per EPA AQS (2024), comfortably inside the Good range, with PM2.5 as the primary pollutant on most measured days. 37.9% of residents in this county are flagged low-access by USDA's 2025 Food Environment Atlas — a notable supermarket-access gap. Alaska has no state income tax (Tax Foundation 2025). IRS migration data (2022-2023) shows a net loss of 229 residents (107 households) — the ZIP's primary county is shrinking. Healthcare access is the area's quieter strength; school options sit on the lighter side, so families may find themselves looking at districts a few ZIPs over. Notable: median household income $86,810, fair market rent of $1,680 for a two-bedroom, and a typical home value of $310,407, up 2.8% over the past year. Every figure on this page links to its underlying federal dataset with a retrieval date so you can audit the freshness yourself.
The two domains pull in different directions. Healthcare access reads strong, but the on-paper school count is on the lighter side — that’s less a quality signal and more a density one. Households here often look at districts a few ZIPs over for school choice while keeping their providers local.
- With fair market rent at $1,680/month (HUD SAFMR) and median household income at $86,810 (Census ACS), housing costs represent approximately 23% of income.
- As a predominantly renter community (61% of occupied units, Census ACS), the 5 schools mapped here by NCES are especially relevant for families weighing the neighborhood.
One concrete reading worth keeping: Depression prevalence sits lower the national rate at 19.1%. Each figure on this page links to the original federal dataset with its retrieval date — this synthesis is a reading, not a substitute for the underlying records.
