Winchester is a town located in Middlesex County, Massachusetts, eight miles north of downtown Boston. It is largely an affluent bedroom community for professionals who work in the greater Boston area. The population was 21,374 at the 2010 United States Census.
According to the United States Census Bureau, the town has a total area of 6.3 square miles (16.3 kmē), of which 6.0 square miles (15.6 kmē) is land and 0.2 square miles (0.6 kmē) is water. The total area is 3.97% water. The town is roughly bisected by a central valley which is the remnant of the original course of the Merrimack River. After glacial debris effectively rerouted the Merrimack north to its current location, all that remained of its original course through present day Winchester is the Aberjona River and the several ponds it feeds en route to the Mystic Lakes on Winchester's southern border. On its eastern third, the valley rises steeply into the wooded hills of the Middlesex Fells Reservation, in which lie the North, Middle, and South Reservoirs. The western edge of the valley yields to Arlington and Lexington heights, and the boundaries with those two towns. To the north, the town's longest border is shared with Woburn. Winchester has several major bodies of water, including the Mystic Lakes, Wedge Pond, Winter Pond, and the Aberjona River, as well as several minor bodies of water such as Sucker Brook and Sachem Swamp. Winchester borders the towns of Woburn, Stoneham, Medford, Arlington, and Lexington.
As of the census of 2000, there were 20,810 people, 7,715 households, and 5,724 families residing in the town. The population density was 3,446.3 people per square mile (1,330.3/kmē). There were 7,908 housing units at an average density of 1,309.6 per square mile (505.5/kmē).
