Fresh.Data current as of Apr 27, 2026
Tyonek, AK (ZIP 99635) sits in Kenai Peninsula Borough. The page draws on 1 federal data feed retrieved Apr 27. Health-survey coverage is limited for this ZIP. NCES lists 1 schools serving the area, 1 non-charter. 3 colleges and universities serve the area, with median in-state tuition of $9,695. Average annual pay across local establishments runs $116,849 per worker (Census ZBP) — a high-wage local economy. The CDC SVI flags housing & transportation (93th percentile) as this ZIP's standout vulnerability dimension, sitting well above its overall 61th-percentile score. FEMA has issued 20 federal disaster declarations affecting this ZIP since 1986 — a high-frequency exposure profile. Median daily AQI is just 8 per EPA AQS (2024), comfortably inside the Good range, with PM2.5 as the primary pollutant on most measured days. Alaska has no state income tax (Tax Foundation 2025). IRS migration data (2022-2023) shows a net gain of 487 residents (267 households) — the ZIP's primary county is growing. Both healthcare access and on-paper school density skew lighter than national norms; what shows up here is a snapshot, not a verdict — neighborhood-level texture matters at this scale. Notable: fair market rent of $1,310 for a two-bedroom and a low 0.0% poverty rate. Every figure on this page links to its underlying federal dataset with a retrieval date so you can audit the freshness yourself.

Both surfaces skew lighter than national averages. That isn’t a verdict — small-area estimates compress real neighborhood-level texture, and a single ZIP reading can miss a district line or a hospital corridor sitting just outside it. Treat this as a starting point for fieldwork, not a conclusion.
