U.S. Census Bureau · 2025 Population Estimates Program (PEP)
Alaska County Population — 2025 PEP
July 1, 2025 resident population estimates for 30 counties. State total (sum of these county estimates): 737,270 persons.
Separate 2025 TIGER/Line county boundaries validate county identity; these are not ACS 2024 survey estimates.
Modern county equivalents include boroughs, municipalities and census areas, including Chugach and Copper River rather than former Valdez-Cordova. Original 2020 counts require separately evidenced compatible geography; incompatible observations remain null with reasons. The revised April estimates base is not an original census count; no boundary allocation is invented.

County population trend · 2020–2025
Resident population (persons), not ACS housing. April 1, 2020 estimates base is distinct from the July 1, 2020 estimate. The April–July 2020 change is partial-year; the July 2020–July 2021 interval is the first July-to-July comparison. No 2020 annual rate is shown. Missing observations are unavailable, never zero.

Horizontal axis: year (2020–2025); vertical axis: resident population (persons). The 2020 base is a separate April 1 observation; July 1 estimates run from 2020 through 2025.

County population and median home value · different vintages
Each point pairs a county’s PEP July 1, 2025 resident population (persons) with its ACS 2024 5-year median owner-occupied home value (B25077, U.S. dollars). These are different reference periods and different statistical programs. This descriptive comparison does not imply causality or matched vintages. Suppressed, missing or invalid ACS estimates are unavailable, not zero and not plotted. A valid zero remains zero.
