Until 1975, the borough was officially named the Borough of Richmond.Staten Island is overall the most suburban of the five boroughs of New York City. The North Shore — especially the neighborhoods of St. George, Tompkinsville, Clifton, and Stapleton — is the most urban part of the island; it contains the officially designated St. George Historic District and the St. Paul’s Avenue-Stapleton Heights Historic District, which feature large Victorian homes. The South Shore has more suburban-style residential neighborhoods and is home to the two and one-half mile long F.D.R. Boardwalk, the fourth longest in the world. Historically, the central and southern sections of the island were dominated by dairy and poultry farms, almost all of which disappeared in the 20th century.

It was closed in 2001, then shortly afterwards reopened to house the debris from the September 11th attacks, and then shortly after closed for good.The borough is accessible to Brooklyn via the Verrazano-Narrows Bridge and to New Jersey via the Goethals Bridge, Outerbridge Crossing, and Bayonne Bridge.
