Westchester County is one of the centrally located counties within the New York metropolitan area. The county is positioned with New York City, plus Nassau and Suffolk counties (on Long Island, across Long Island Sound), to its south; Putnam County to its north; Fairfield County, Connecticut to its east; and Rockland County and Bergen County, New Jersey across the Hudson River to the west. Westchester was the first suburban area of its scale in the world to develop, due mostly to the upper-middle-class development of entire communities in the late 19th century and the subsequent rapid population growth. Because of Westchester's numerous road and mass transit connections to New York City, as well as its shared border with the Bronx, the 20th and 21st centuries have seen much of the county, particularly the southern portion, become nearly as densely developed as New York City itself.
