Lehigh Valley - Cities and Location

Cities and Location

The Lehigh Valley's principal cities are Allentown, Bethlehem, and Easton, comprising the Allentown-Bethlehem-Easton metropolitan area. The traditional bounds of the region are The Poconos to the north, the Delaware River to the east, the boundaries of Berks County and Montgomery County to the southwest, and the boundary with Bucks County to the south. More recently, however, the area around Phillipsburg, New Jersey west of Pohatcong Mountain, parts of upper Bucks County around Quakertown, and portions of northeastern Berks County and southwestern Carbon County in Pennsylvania are considered outer parts of the Valley.

The Lehigh Valley is located approximately 60 miles (96 km) north of Philadelphia, the country's fifth largest city, 80 miles (129 km) east of Harrisburg, Pennsylvania's capital, and 70 miles (144 km) west of New York City, the country's largest city. The area is home to more than 820,000 people as of the 2010 U.S. Census. Recent census studies show it to be the fastest growing region in Pennsylvania, due in part to its growing popularity as a bedroom community for the highly-populated neighboring regions of Philadelphia, New Jersey and New York City as well as its favorable business climate and much lower cost of living in comparison to surrounding areas.

The Lehigh Valley is geologically and geographically part of the Great Appalachian Valley, a region largely made up of limestone that stretches along the eastern edge of the Appalachian Mountains. The Lehigh Valley is so named because it is composed of an actual valley that lies between two mountain ranges, Blue Mountain to the north and South Mountain to the south. Lehigh Valley also is considered part of the historic Pennsylvania Dutch Country.
