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. |
