White Plains is a city in Westchester County, New York, United States, and the eleventh-largest city in the state. An inner suburb of New York City, it is the county seat and commercial hub of Westchester, a densely populated suburban county that is home to approximately one million people. White Plains is located in south-central Westchester, with its downtown (Mamaroneck Avenue) 25 miles (40 km) north of Midtown Manhattan.
As of 2013, the city's total population was estimated to be 57,866, up from 53,077 at the 2010 census. According to the city government, the daytime weekday population is estimated at 250,000. The city was ranked third in the top 10 places to live in New York for 2014, according to national online real estate brokerage Movoto.
At the time of the Dutch settlement of Manhattan in the early 17th century, the region had been used as farmland by the Weckquaeskeck tribe, a Wappinger people, and was called "Quarropas". To early traders it was known as "the White Plains", either from the groves of white balsam which are said to have covered it, or from the heavy mist that local tradition suggests hovered over the swamplands near the Bronx River. The first non-native settlement came in November 1683, when a party of Connecticut Puritans moved westward from an earlier settlement in Rye and bought about 4,400 acres (18 km2), presumably from the Weckquaeskeck. However, John Richbell of Mamaroneck claimed to have earlier title to much of the territory through his purchase of a far larger plot extending 20 miles (32 km) inland, perhaps from a different tribe. The matter wasn't settled until 1721, when a Royal Patent for White Plains was granted by King George II.
In 1758, White Plains became the seat of Westchester County when the colonial government for the county left West Chester, which was located in what is now the northern part of the borough of the Bronx, in New York City.
