Alaska metro-by-metro prices
Alaska has one metro in our dataset, Anchorage, so the statewide and metro figures are close. The state figure uses BLS statewide wages, which include rural areas. Each row prices the default size with that metro's own BLS wages and BEA price levels, so the gap between rows is real local variation rather than a flat markup.
| Metro | Range (1,000 sq ft) | Midpoint | vs. state |
|---|---|---|---|
| Anchorage, AK | $1,100 – $4,400 | $2,750 | level |
