The data below covers the population from all 19 boroughs and 11 census areas that make up the 1 unorganized borough, from the 2021 census conducted by the US Census Bureau. We have included population estimates for 2022 and noted the changes in populations for each borough or area in Alaska.

It’s worth noting that many areas are showing a decline in population, but main population hubs like Anchorage and the Kenai Peninsula have shown a large increase in their numbers from just two years of data.

Alaska draws people who may be touring the state, who then go home and make a plan to move up to Alaska.

Overall, Alaska’s population has been declining since peaking at 742,575 in 2016 as more people are leaving the state than people moving up to Alaska. Alaska’s last population estimate for 2022 stands at 736,556, provided by Department of Labor and Workforce Development.
