Economy of Long Island

Counties of Nassau and Suffolk have been long renowned for their affluence.

From about 1930 to about 1990, Long Island was considered one of the aviation centers of the United States, with companies such as Grumman Aircraft, Republic, Fairchild, and Curtiss having their headquarters and factories on Long Island.

Long Island has played a prominent role in scientific research and in engineering. It is the home of the Brookhaven National Laboratory in nuclear physics and Department of Energy research.

In recent decades companies such as Sperry Rand, Computer Associates (headquartered in Islandia), Motorola Enterprise Mobility (now occupying the former headquarters of Symbol Technologies and a former Grumman plant in Holtsville), have made Long Island a center for the computer industry. Stony Brook University of the State University of New York conducts far-ranging medical and technology research.

Long Island is also home to the Cold Spring Harbor Laboratory, which was directed for 35 years by James D. Watson (who, along with Francis Crick, discovered the double helix structure of DNA).

Long Island is home to the East Coast's largest industrial park, the Hauppauge Industrial Park. The park has over 1,300 companies employing more than 55,000 Long Islanders. Companies in the park and abroad are represented by the Hauppauge Industrial Association. As many as 20 percent of Long Islanders commute to New York City jobs. The eastern end of the island is still partly agricultural. In the last 25 years, development of vineyards on the North Fork became a major new industry, replacing potato fields. Pumpkin farms have been added to traditional truck farming. Farms allow fresh fruit picking by Long Islanders for much of the year. Fishing continues to be an important industry, especially at Huntington, Northport, Montauk, and other coastal communities of the East End and South Shore.
