Pennsylvania metropolitan areas

Pennsylvania has fourteen metropolitan statistical areas (MSAs) and four combined statistical areas (CSAs), as defined by the United States Census Bureau. A map of the Pennsylvania MSAs is available from the Census Bureau. As of 2016 Philadelphia is the seventh largest United States metropolitan area.[1] In 2003, the U.S. Census introduced "metropolitan divisions" within some metropolitan areas. Pennsylvania has one metropolitan division within the Philadelphia–Camden–Wilmington MSA.
