The U.S. Census Bureau reported today on where the heaviest population growth in Pennsylvania was concentrated last year
The fastest-growing county in Pennsylvania between July 1, 2012, and July 1, 2013, was Cumberland whose population rose 0.9 percent over the period. Cumberland county was followed by Lancaster county (0.6 percent), Chester county (0.6 percent), Franklin county (0.5 percent) and Clinton county (0.5 percent).
With respect to numerical growth, Philadelphia added 4,518 people over the period, more than any other county in the state. It was followed by Montgomery county, which grew by 3,430 people, Chester county (3,278), Lancaster county (3,164) and Cumberland county (2,048).
Philadelphia is the most populous county in Pennsylvania with 1,553,165 residents, followed by Allegheny county and Montgomery county.
This information is based on annual population estimates for each of the nation’s counties, county equivalents, metropolitan areas and micropolitan areas since the 2010 Census and up to July 1, 2013. Internet tables are available showing rankings and components of population change (births, deaths, migration).
Later this year, data will be available from County Business Patterns, which provide the economic side of the story. Annual statistics will be released on the number of establishments, employees and annual payroll for nearly 1,200 industries at the national, state and county levels. Statistics on the number of people who commute from one specific county to another will also be released this spring.
