Park Slope is a neighborhood in the western section of Brooklyn, New York City's most populous borough. Park Slope is roughly bounded by Prospect Park West to the east, Fourth Avenue to the west, Park Place to the north and 15th Street to the south, though other definitions are sometimes offered. It takes its name from its location on the western slope of neighboring Prospect Park. Seventh Avenue and Fifth Avenue are its primary commercial streets, while its east-west side streets are populated by many historic brownstones. Park Slope is characterized by its historic buildings, top-rated restaurants, bars, and shops, as well as close access to Prospect Park, the Brooklyn Academy of Music, the Brooklyn Botanic Garden, the Brooklyn Museum, the Brooklyn Conservatory of Music, and the Central Library (as well as the Park Slope branch) of the Brooklyn Public Library system. The neighborhood had a population of about 62,200 as of the 2000 census,resulting in a population density of approximately 68,000/square mile, or approximately 26,000/square kilometer. In December 2006, Natural Home magazine named Park Slope one of America's ten best neighborhoods based on criteria including parks, green spaces and neighborhood gathering spaces; farmer’s markets and community gardens; public transportation and locally-owned businesses; and environmental and social policy.
