CHEYENNE – About three-quarters of larger cities and towns in Wyoming lost residents between July 1, 2017, and July 1, 2018, according to population estimates released by the U.S. Census Bureau. These estimates provide a look at how the population has changed in each of Wyoming’s incorporated places since the 2010 census.
For cities and towns with a population over 2,000, Cheyenne demonstrated the fastest annual growth rate of 0.6%, followed by Cody (0.5%), Mills (0.4%) and Buffalo (0.4%).
Cheyenne, the state’s most populous city, also added the most residents (370). Six cities and towns experienced population losses of at least 1.2%, led by Thermopolis’ 2.8% decrease (81 residents). Casper and Rock Springs lost the most population during the year, at -351 and -291, respectively.
As of July 1, 2018, 68.8% (397,611) of Wyoming residents lived in incorporated places. More than 47% of the state’s residents lived in 10 cities with a population of more than 10,000.
Due to the moderate recovery in the energy industry, Wyoming’s total population in 2018 was 1,197 less than the previous year (-0.2%). In comparison, the previous year’s decline was 5,356 residents, or 0.9%. However, the total contraction rate in the 99 cities and towns was 0.3% between July 2017 and July 2018.
