The Census Bureau defines an
urbanized area wherever it finds an urban nucleus of 50,000 or more people.
They may or may not contain any individual cities of 50,000 or more (152
currently do not). In general, they must have a core with a population
density of 1,000 persons per square mile and may contain adjoining territory
with at least 500 persons per square mile. Urbanized areas have been delineated
using the same basic threshold (50,000 population) for each decennial
census since 1950, but procedures for delineating the urban fringe are
more liberal today. In 2000, 68 percent of Americans lived in 452 urbanized
areas.

Urban areas are of two types—urbanized
areas and urban clusters—identical in the criteria used
to delineate them but different in size. The Census Bureau defines an
