Queens is a borough of New York City, coextensive with Queens County, in the U.S. state of New York. It is the largest borough of New York City in area and is adjacent to the borough of Brooklyn at the western end of Long Island, with Nassau County to the east. Queens is the most linguistically diverse place on Earth and is one of the most ethnically diverse counties in the United States.
Queens has the most diversified economy of the five boroughs of New York City. It is home to John F. Kennedy International Airport and LaGuardia Airport. Landmarks in Queens which support its economy include Flushing Meadows–Corona Park; Citi Field, home to the New York Mets baseball team; the USTA Billie Jean King National Tennis Center, site of the U.S. Open tennis tournament; Kaufman Astoria Studios; Silvercup Studios; and the Aqueduct Racetrack. Flushing is undergoing rapid gentrification with investment by Chinese transnational entities, while Long Island City is undergoing gentrification secondary to its proximity across the East River from Manhattan.
The borough has diverse housing, ranging from high-rise apartment buildings in some areas of western and central Queens, such as Ozone Park, Jackson Heights, Flushing, Astoria, and Long Island City, to neighborhoods with many low-rise structures in the eastern part of the borough. The Queens Night Market in Flushing Meadows-Corona Park attracts thousands nightly to sample food from dozens of countries.
