Places, 1970, 1980, & 1990
Typically, places are discrete settlements, usually occupying only a portion of the county in which they are located. Places may extend across county boundaries but never across state boundaries. Census places are of two types - Incorporated Places, such as cities, villages, or towns, which have legally prescribed powers and functions; and Census Designated Places, (CDPs, previously "unincorporated areas"), which are densely settled areas (at least 1,000 persons per square mile) with a locally-used distinctive name. Places are a possible substitute for "neighborhood" if tract, block numbering area, and enumeration district are unavailable.
