Suffolk County, New York

Suffolk County is a county located in the U.S. State of New York. As of 2000, the population is 1,419,369. It was named for Suffolk, a county in England, from which its earliest settlers came. Its county seat is Riverhead. Suffolk and Nassau counties are generally referred to as "Long Island" (as distinct from New York City) by area residents.

Suffolk County was an original county of New York State, one of twelve created in 1683. Its boundaries were substantially the same as at present, with only minor changes in the boundary with its western neighbor, which was originally Queens County but since 1899 has been Nassau County. However, as Suffolk has become more suburban there has been agitation by people living in the more rural East End of the island to divide Suffolk into two counties. Supporters of the idea feel that this would give them a larger voice in the proposed county government than they have in Suffolk as it now stands.
