Maplewood is a suburban township in Essex County, New Jersey, United States. As of the 2010 United States Census, the township's population was 23,867, reflecting a decline of 1 person (0.0%) from the 23,868 counted in the 2000 Census, which had in turn increased by 2,216 (+10.2%) from the 21,652 counted in the 1990 Census.HistoryWhen surveying the area now known as Maplewood, Robert Treat found several trails used by Lenape tribes of Algonquian Native Americans, though there was only sparse pre-European settlement. These paths form the basis for what are the town's main thoroughfares today.The first European settlers arrived around 1675, primarily English, Dutch and French Puritans who had earlier settled Hempstead, Long Island, and Stamford, Connecticut, via Newark and Elizabeth. They had acquired most of today's Essex County from the Native Americans and followed three trails that roughly correspond to South Orange Avenue, Springfield Avenue, and Ridgewood Road. These three routes resulted in the development of three separate communities that coalesced to become Maplewood and South Orange.
