STATE IMPACT PENNSYLVANIA -- The commonwealth's population growth has been concentrated in the State College area, suburban Pittsburgh and southeastern Pennsylvania.
The state's population is on the rise again, after declining last year - but growth remains concentrated in certain spots, and most communities keep losing residents.
The U.S. Census Bureau's population estimates show the state lost people during 2016, but added more than 18,000 last year, the most since 2012, according to a Keystone Crossroads analysis of the latest statistics.
Major growth pockets are, as in recent years, in the State College area, and in the city of Philadelphia and its suburbs, according to a recent Penn State Data Center report based on Census estimates.
Growing urban centers also include Allentown, Bethlehem, Lancaster and Scranton. But just 12 cities, about a quarter, have added residents since the last decennial census.
Populations also are declining in more than 75 percent of boroughs, according to the Center's report.
Two-thirds of townships lost residents, too.
