List of Pennsylvania counties by per capita income

The wealthiest regions of Pennsylvania are the suburban counties bordering Philadelphia, the state's most populous city.

One area known for its historic wealth is the Philadelphia Main Line, which includes Lower Merion, Radnor, Tredyffrin, Easttown, and Willistown townships.

Some of Pennsylvania's most affluent neighborhoods and priciest real estate are located in communities located in these townships, including Ardmore, Bala Cynwyd, Gladwyne, Haverford, and Villanova.

The Northeast wealth corridor also runs through Montgomery County, highest in the area of Whitpain, Lower Gwynedd, Plymouth, Upper Dublin and Whitemarsh townships; and into areas of Bucks County especially the area around New Hope, such as Solebury, Lower Makefield, and Upper Makefield townships.

Outside of the Philadelphia, Pittsburgh, and Harrisburg metropolitan areas, Pennsylvania is a relatively poorer state, especially in the northern areas and the Appalachian Mountains; only 22% of Pennsylvania places have per capita incomes higher than the national per capita income, and 11.0% of the population lives below the poverty line.
