Census-designated place
A census-designated place (CDP) is an unincorporated concentration of population with a definite residential nucleus, such as Whitmore Lake, Michigan. In other words, it is a place that is counted as a city or municipality while counting people in the census, because it resembles them in population density and structure, but which has not any town rights or a city council.
