Broome County in the U.S. state of New York, as of the 2010 United States Census, had a population of 200,600. Its county seat is Binghamton. The county was named for John Broome, the state’s lieutenant governor when Broome County was created.
Broome County lies on the south line of New York. Its south border abuts the north border of the state of Pennsylvania. The Susquehanna River flows southward through the eastern part of the county, enters Susquehanna County in Pennsylvania, then re-enters Broome and flows northwestward to meet the Chenango River at Binghamton. The combined flow moves west-southwestward into Tioga County to the west. The West Branch Delaware River flows southward along the lower portion of the county’s east border, delineating that portion of the border between Broome and Delaware counties.
The county’s western portion is hilly, with wide valleys that accommodate Binghamton and its suburbs. In the northern portion, Interstate 81 traverses a wide glacial valley. The east part of the county is much more rugged, as the land rises to the Catskill Mountains. The terrain generally slopes to the west. The county’s highest point is in the northwest of the county, a U.S. National Geodetic Survey benchmark known as Slawson atop an unnamed hill in the Town of Sanford. It is approximately 2087 feet (636 m) above sea level. An area due east on the Delaware County line in Oquaga Creek State Park also lies within the same elevation contour line. The lowest point is 864 feet (263 m) above sea level, along the Susquehanna River, at the Pennsylvania state line.
