HARRISBURG — Data released this week by the U.S. Census Bureau reveals that Pennsylvania’s population grew by a sluggish 2.4% between 2010 and 2020.

Among the state’s 67 counties, the population in 44 declined during that decade-long span, with rural counties in the western and northern parts of Pennsylvania hit hardest. Counties in southeast and south-central Pennsylvania were among the top gainers.
