In the 19th century, factories in cities such as Camden, Paterson, Newark, Trenton, and Elizabeth helped to drive the Industrial Revolution. New Jersey's geographic location at the center of the Northeast megalopolis, between Boston and New York City to the northeast, and Philadelphia, Baltimore, and Washington, D.C., to the southwest, fueled its rapid growth through the process of suburbanization in the second half of the 20th century. In the first decades of the 21st century, this suburbanization began reverting to consolidation of New Jersey's culturally diverse populace toward more urban settings within the state, with towns home to commuter rail stations outpacing the population growth of more automobile-oriented suburbs since 2008.
