Wyoming population expanded at a measured pace in 2025

CHEYENNE (WNE) — Wyoming’s total resident population grew to 588,753 in July 2025, according to estimates just released by the U.S. Census Bureau.

The annual increase from July 2024 was 2,031 people, representing a growth rate of 0.3%. This increase was slightly lower than the 0.4% annual growth recorded in 2024.

The two factors that contribute to population change are natural change from vital events and net migration from people’s movement. The natural change, calculated as 6,070 births minus 5,775 deaths, was 295. The estimated net migration, defined as in-migration minus out-migration, was 1,732, indicating that 1,732 more persons moved into Wyoming than moved out of the state between July 2024 and July 2025. In contrast, for the previous two years, net migration was 2,592 in 2023 and 1,781 in 2024, respectively.

Nationally, the estimated population was 341.8 million in 2025, reflecting an increase of 0.5% from the previous year. This is the slowest annual growth since 2021, primarily due to a historic decline in net international migration, from 2.7 million in 2024 to 1.3 million in 2025. 

All neighboring states experienced a faster population increase than Wyoming, which had the 32nd fastest growth rate in the country in 2025. Since the 2020 Census, the state added 11,881 residents (or 2.1%), the 29th highest in population growth in the U.S.

The state experienced nearly six consecutive years of negative net migration (more people left than moved into the state) between 2014 and 2019 due to the downturn in the energy industry.
