Suffolk County is a county located in the U.S. state of New York on the eastern portion of Long Island. As of the 2000 census, the population was 1,419,369. It was named for the county of Suffolk in England, from which its earliest settlers came. The county seat is Riverhead, though many county offices are in Hauppauge on the west side of the county where most of the population lives. There are also offices in Smithtown, for the legislature, Yaphank, and Farmingville.

Suffolk and Nassau counties together are generally referred to as “Long Island” by area residents — as distinct from the New York City boroughs of Queens (Queens County) and Brooklyn (Kings County), which geographically make up the island’s western end.

In 2005, Forbes Magazine named Suffolk County, along with Nassau County, New York, as the safest region in the United States, with the lowest crime rate.

Suffolk County is among the top 40 richest counties in the nation, according to Forbes Magazine.
