(By Kyle Kondik, political analyst at UVA’s Center for Politics) The U.S. Census Bureau recently reported changes in population from 2020 to 2021. While the headline findings mainly dealt with population declines, a number of places (particularly in the Sun Belt) are still experiencing substantial growth. A little more than five dozen counties with at least 100,000 residents grew by 3% or more from April 2020 to July 2021. These counties are spread across 20 states.
