The population was 12,023 at the 2010 census. The town is named after early farmer Matthew Paterson. The reason Patterson was spelled with two "t"s was due to the looseness with which Paterson spelled his own last name. ^source

Area code 845 is a telephone area code straddling the Hudson Valley region of the U.S. state of New York. It serves Rockland, Putnam, Orange, and Ulster counties; most of Dutchess and Sullivan counties, plus parts of Delaware, Greene, and Columbia counties. Area code 845 was created on June 5, 2000 from most of area code 914, which was retained by Westchester County. 845 was the first new area code in New York (outside the New York City metropolitan area and Long Island) since 1954. ^source
