Understanding Long Island

Long Island has changed dramatically since The New York Community Trust opened an office there in 1978 (originally known as the Long Island Community Foundation). Over four decades, Long Island has changed in density, demographics, and populations in need, with at-risk communities growing and diversifying. In the last decade, the rise in suburban poverty has surpassed the rise in urban poverty.

The poverty rate on Long Island is approximately 5.9 percent—with an average poverty rate of 5.41 percent in Nassau County and 6.5 percent in Suffolk County. This means that approximately 166,000 people are living below the national poverty line. Yet even this staggering statistic does not tell the whole story.
