Bridgeport is the most populous city in the American state of Connecticut, the 5th-most populous in the New York Metropolitan area, and the 5th-most populous in New England. Located in Fairfield County at the mouth of the Pequonnock River onto Long Island Sound, the city had a population of 144,229 during the 2010 Census. It is bordered by the towns of Trumbull to the north, Fairfield to the west, and Stratford to the east. The Greater Bridgeport area is the 48th-largest urban area in the United States, just behind Hartford (47th), and forms part of the Greater New York City Area.
Bridgeport was inhabited by the Paugussett Indian tribe at the time of its English colonization. The English farming community became a center of trade, shipbuilding, and whaling. The town incorporated itself to subsidize the Housatonic Railroad and rapidly industrialized following its connection to the New York and New Haven railroad. Manufacturing was the mainstay of the local economy until the 1970s. Industrial restructuring and suburbanization caused the loss of many jobs and affluent residents, leaving Bridgeport struggling with problems of poverty and crime. In the 21st century, conversion of office and factory buildings to residential use and other redevelopment is attracting new residents.
The showman P.T. Barnum was a resident of the city and served as the town's mayor in the late 19th century. Barnum built four houses in Bridgeport, and housed his circus in town during winter. The first Subway restaurant opened in the North End section of the city in 1965. The Frisbie Pie Company was located here, and Bridgeport is credited as the birthplace of the Frisbee.
