Business improvement districts in the United States (BIDs), also known as local improvement districts (LIDs), are United States special districts[1] within a city that are overseen by a nonprofit entity. In the United States, business improvement districts are typically funded by an additional tax assessment,[2] with the tax increase going toward improvements of the area.
By 2010, BIDs had been used in nearly 1,000 major cities and small towns throughout the United States, including most major U.S. cities that have multiple BIDs. New York City alone has 76 BIDs.
Business improvement districts are private sector initiatives to improve the environment of a business district. Services financed by a BID are intended to enhance existing city services, not replace public works or economic development departments. [3]
