Wyoming is still gaining residents, but the real story isn’t how many people are moving in — it’s how quickly the state’s population is aging. That reflects years of lower birth rates and a growing number of older residents. The number of residents age 65 and older grew at a faster rate than the overall population, making the state’s median age rise more quickly than the national average. Wenlin Liu, chief economist with the state’s Economic Analysis Division, bluntly described the demographic shift: the state’s older population is growing fast, while outmigration of young people and lower birth rates continue to shrink the pool of working-age Wyomingites. Surveys of Wyoming residents mirror that concern.
