Neighborhoods in New York City do not have official status, and their boundaries are not specifically set by the city. (There are a number of Community Boards, whose boundaries are officially set, but these are fairly large and generally contain a number of neighborhoods, and the neighborhood map issued by the Department of City Planning only shows the largest ones.) Because of this, the definition of where neighborhoods begin and end is subject to a variety of forces, including the efforts of real estate concerns to promote certain areas, the use of neighborhood names in media news reports, and the everyday usage of people.
