| Sep 10, 2025 Wyoming’s economic issues are more urgent than we realize (Khale J. Lenhart) “Wyoming ranks last at retaining its young people, with the highest out-migration rate in the country. Census numbers also show that, despite a statewide population increase of around 3.3% between 2010 and 2020, almost every age demographic saw population losses in Wyoming, except the 65 and older demographic, which saw an increase of over 48%.This is troubling, as it shows we are losing our productive-aged population. There is little doubt that the lack of economic opportunities plays a real role.” |
