The Philadelphia–Reading–Camden combined statistical area includes sixteen counties in four states. The five Pennsylvania counties in the metropolitan statistical area are collectively known as Southeastern Pennsylvania. In addition to Philadelphia, major municipalities in Southeastern Pennsylvania include the inner suburbs of Upper Darby Township and Bensalem Township. Berks County, which forms its own MSA and contains the CSA's second largest city, Reading, is occasionally not considered to be part of Southeastern Pennsylvania and is sometimes assigned to South Central Pennsylvania.
