About Plainsboro
Plainsboro Township is a township situated in southern Middlesex County, in the U.S. state of New Jersey. Centrally located in the Raritan Valley region, the township is an outer-ring suburb of New York City in the New York metropolitan area, even though it is slightly geographically closer to Center City, Philadelphia than to Midtown Manhattan. As of the 2020 United States census, the township's population was 24,084, its highest decennial count ever and an increase of 1,085 (+4.7%) from the 22,999 recorded at the 2010 census, which in turn reflected an increase of 2,784 (+13.8%) from the 20,215 counted in the 2000 census.
Plainsboro was incorporated as a township on May 6, 1919, from lands north of Plainsboro Road and Dey Road that had been part of South Brunswick and lands south of Plainsboro Road and Dey Road that had been part of Cranbury. The main impetus towards the creation of the township was the lack of schools serving the area; a new school was constructed after the township was established, which still exists as J.V.B. Wicoff School, named for one of the individuals who led the effort to create Plainsboro.
