Alaska’s population is heavily concentrated in the south-central region, with Anchorage Municipality having about 284,000 residents despite a 2.3% decline since 2020. The fastest-growing region is the nearby Matanuska-Susitna Borough, which has grown 10.5% to nearly 119,000 residents. While Fairbanks North Star Borough remains the third-largest at 94,000 residents, rural areas are seeing significant population losses, with Lake and Peninsula Borough experiencing a 14.6% decline and the Kusilvak Census Area dropping 9.5%. The state shows extreme population density contrasts, from Anchorage’s 167 people per square mile to vast areas like the Yukon-Koyukuk Census Area, which despite covering 145,582 square miles has fewer than 0.03 people per square mile.
