Milton is a city in Fulton County, Georgia, United States. Incorporated on December 1, 2006, it was created out of the entire unincorporated northwestern part of northern Fulton County. It is a highly affluent community with an average household income within the zip code 30004 of $99,412. According to the 2010 Census, Milton's population is 32,661. Milton was not named for any of its historic communities, but rather because northern Fulton County (generally north of the Chattahoochee River) is almost entirely the former Milton County, which was in turn named for either John Milton or Homer V. Milton.
