Long Island is the largest island that is connected to the United States mainland. It is just east of Manhattan. Long Island contains four counties, two of which are boroughs (Queens and Brooklyn) of New York City, and two of which (Nassau and Suffolk) are mainly suburban.
Long Island is known for its affluence and high quality of life. According to Forbes Magazine, as of March, 2010, Nassau and Suffolk Counties are among the top 25 richest counties in America. Additionally, Nassau County is the third richest county per capita in New York State, and the 30th richest in the nation.
Nassau was the fastest growing county in the United States from the 1950s to the 1970s. Suffolk County remains less congested despite substantial growth in high technology and light manufacturing sectors since 1990. In its far east sections, Suffolk remains to be a small, rural town, as in Greenport on the North Fork and some of the outward areas of The Hamptons, although summer tourism swells the population.
