Are there enough branches left? The national network of around 87,000 bank branches — down from 95,000 in 2008 — works out to around 1 bank location per 3,700 Americans. In generally affluent Montgomery County, even after the recent closings, there is still one branch per 2,700 residents. But in Philadelphia, home to many of the poorest Pennsylvanians, banks are relatively scarce: the city showed 1 branch per 5,600 residents, less than half the concentration in Montco.
