Broome County, New York
Broome County in the U.S. state of New York, as of the 2010 census, had a population of 200,600. Its county seat is Binghamton. The county was named in honor of John Broome, who was lieutenant governor in 1806 when Broome County was established.
When counties were established in the Province of New York in 1683, the present Broome County was part of the enormous Albany County, including the northern part of New York State as well as all of the present State of Vermont and, in theory, extending westward to the Pacific Ocean. This county was reduced in size on July 3, 1766 by the creation of Cumberland County, and further on March 16, 1770 by the creation of Gloucester County, both containing territory now in Vermont.
