Mount Vernon is a city in Westchester County, New York, United States. It lies on the border of the New York City borough of the Bronx. As of the 2010 census, Mount Vernon had a population of 67,292.
In 1894, the voters of Mount Vernon (and nearby Yonkers) voted, along with the voters of Kings County (present day Brooklyn), Queens County, and Richmond County (present day Staten Island), in a referendum on whether or not they wanted to become part of a "Greater New York City". While the results were positive elsewhere, the returns were so negative in Mount Vernon and Yonkers that those two areas were not included in the consolidated city and remained independent.Unlike neighboring Wakefield (in the Bronx), which was named after the plantation where George Washington was born, Mount Vernon was not named after a site associated with George Washington; the naming of the city of Mount Vernon precedes the eponymous Virginia plantation where Washington spent his final years. Anne Hutchinson founded the Westchester city in the 17th Century and named it for its green mount (hence the name, Mount Vernon).The Mount Vernon Public Library, a gift to the city from philanthropist Andrew Carnegie, opened in 1904 and is now part of the Westchester Library System, providing educational, cultural and computer services to county residents of all ages.During the 1960s, Mount Vernon was a divided city on the brink of a "northern style" segregation. Many blacks from the Southern United States migrated north and settled in the city of Mount Vernon for better job opportunities and educational advancements. At the same time, many White Americans from the Bronxand Manhattan looked to Mount Vernon as a new "bedroom community" due to rising crime in New York City (a "white flight" factor entailed as well). As a result, Mount Vernon became divided in two by the New Haven Line railroad tracks of the Metro North railroad: Northside and Southside.
