Wyoming’s total resident population grew slightly to 578,803 in July, 2021 according to estimates just released by the US Census Bureau.
The annual increase from 2020 was 1,536 persons, or 0.3%. Teton County itself grew by .82%. According to the state Division of Economic Analysis, there are two factors that contribute to population change: natural increase and net migration.
The natural increase is the number of births minus the number of deaths. Wyoming had 6,213 births minus 6,042 deaths for a natural increase of 171 this past July. Estimated net migration is in‐migration less outmigration. Wyoming’s net migration was about 1,368. This positive net migration means that 1,368 more residents moved into Wyoming than moved out of the State between July 2020 and July 2021.
Half of the top ten states with the largest annual percent population growth were in the West, led by Idaho, with the nation’s highest annual percent growth, 2.9%, followed by Montana and Utah with annual growths of 1.7%.
