Cumberland County No. 1 for population growth now, but what about 2040?

Cumberland County grew the most of any county in the commonwealth, by percentage, between April 2010 and July 2014.

Long-term projections have Cumberland County continuing as one of the fastest-growing counties through 2040.

The current projection is 19.2 percent growth between 2010 and 2040, while neighboring Dauphin County is expected to grow by 10.7 percent over that span.
