At more than 100 miles in length, Long Island is part of which state?

Long Island, which measures over 100 miles in length, is part of New York State. It is situated in the southeastern part of the state, extending into the Atlantic Ocean. Long Island is notable for its large population and is home to several well-known regions such as Nassau and Suffolk County, as well as the affluent area of the Hamptons.

The island's significance to New York is further highlighted by its proximity to New York City, with communities such as Queens and Brooklyn located on the western portion of Long Island. This geographical connection establishes Long Island not only as an essential residential area for many who work in the city but also as a cultural and economic hub in its own right.

Long Island's size and status contrast with the other states listed; Washington, California, and Massachusetts do not include Long Island within their geographical boundaries. Thus, the identification of Long Island as part of New York is crucial in understanding the region's significance in both local and national contexts.
