Determination of U.S. Area and Population 
Inside and Outside of Urbanized Areas

U.S. Census Bureau defined Urbanized Areas, from the 2000 census, of at least 100,000 persons were selected. The total population and aerial extent of the selected areas were then compared to the 2000 census totals for the U.S. population and the aerial extent of the U.S.

Total Population

Aerial Extent (sqm)

U.S. States (Generalized)

100% 281,421,906

U.S. States (Generalized) represents the 50 states and the District of Columbia of the United States.

U.S. Census Urbanized Areas represents the Census 2000 Urbanized Areas (UA) and Urban Clusters (UC). A UA consists of contiguous, densely settled census block groups (BGs) and census blocks that meet minimum population density requirements (lOOOppsm /SOOppsm), along with adjacent densely settled census blocks that together encompass a population of at least 50,000 people. A UC consists of contiguous, densely settled census BGs and census blocks that meet minimum population density requirements, along with adjacent densely settled census blocks that together encompass a population of at least 2,500 people, but fewer than 50,000 people. The dataset covers the 50 States plus the District of Columbia within United States.
