A central business district (CBD) is an area of very high land valuation characterized by a high concentration of retail businesses, service businesses, offices, theaters, and hotels, and by a very high traffic flow. A CBD was defined in the 1982 Census of Retail Trade to follow existing census tract boundaries; that is, it consisted of one or more whole census tracts.
The Census Bureau discontinued the CBD program following the 1982 Census of Retail Trade.
