Notes:
There are two kinds of places in Census Bureau terminology: incorporated places and Census Designated Places (CDPs).
A place is a concentration of population legally bounded as an incorporated place. A CDP is delineated for statistical purposes as a census designated place (in Puerto Rico, a comunidad or zona urbana). These are created for the purpose of presenting census data for an area with a concentration of population, housing, and commercial structures that is identifiable by name, but is not within an incorporated place. For Census 2000, for the first time, CDPs did not need to meet a minimum population threshold to qualify for tabulation of census data.
As you can see in this map taken from the American FactFinder, the boundaries of places - either incorporated or CDPs - do NOT necessarily correspond to census tracts, block groups or MCDs.
Speaker note: CDP boundaries, which usually coincide with visible features or the boundary of an adjacent incorporated place or other legal entity boundary, have no legal status, nor do these places have officials elected to serve traditional municipal functions. CDPs usually are delineated in cooperation with state, Puerto Rico, Island Area, local, and tribal officials based on U.S. Census Bureau guidelines.
