According to the 1990 census
definition, the urban population comprises all persons living in (a) places of 2,500 or
more inhabitants incorporated as cities, villages, boroughs (except in Alaska and New
York), and towns (except in the New England states, New York, and Wisconsin), but
excluding those persons living in the rural portions of extended cities (places with low
population density in one or more large parts of their area); (b) census designated places
(previously termed unincorporated) of 2,500 or more inhabitants; and (c) other territory,
incorporated or unincorporated, included in urbanized areas. An urbanized area comprises
one or more places and the adjacent densely settled surrounding territory that together
have a minimum population of 50,000 persons. |

In censuses prior to 1950, the urban population comprised
all persons living in incorporated places of 2,500 or more inhabitants and areas (usually
minor civil divisions) classified as urban under special rules relating to population size
and density. To improve its measure of the urban population, the Bureau of the Census in
1950 adopted the concept of the urbanized area and delineated boundaries for
unincorporated places. The 1950 definition has continued substantially unchanged, except
for minor modifications in 1960, the introduction of the extended city concept in 1970,
and changes since the 1970 census in the criteria for defining urbanized areas so as to
permit such areas to be defined around smaller centers. In all definitions, the population
not classified as urban constitutes the rural population. |
