Understanding Urban Population: Definitions and Examples in the US

Urban population is a critical aspect of demographic studies that often influences policy-making and resource allocation. In the United States, the U.S. Census Bureau provides a detailed and nuanced framework to classify urban areas, which significantly differs from how the term is commonly understood in popular culture.

Definitions and Key Terms

When using the definitions provided by the U.S. Census Bureau, there are three key terms to understand:

Urban Area: An area with a population of at least 50,000 people. Urban Cluster: An area with a population of at least 2,500 to less than 50,000 people. Rural Area: Any community that does not fall into the categories of Urban Area or Urban Cluster.

According to these definitions, any population cluster with at least 2,500 people is considered urban, even if it is the smallest town. This is quite different from the standard used in popular culture, where 'urban' often refers to large cities like New York or Chicago.

Urban Population in Context

Urban population refers to the population residing in urban areas. In the U.S., this is defined using Census data and the standards set by the Office of Management and Budget (OMB). The convention is to include whole counties within the definition of an urban area, be it a metropolitan or micropolitan area.

Metropolitan Statistical Area (MSA)

The definition of a metropolitan statistical area (MSA) includes a central city and the surrounding areas that are economically and socially connected. These areas form a distinct urban region. Critics often point out that MSA definitions can be broad, and rural areas with agricultural uses are sometimes included in these urbanized regions. The process of land development for urban use can be a gradual one, changing the landscape over time.

Examples of Metropolitan and Combined Statistical Areas

Let's delve into a few examples to illustrate these concepts:

Chicago Metropolitan Area

The Chicago metropolitan area is a U.S. urban area encompassing the Metropolitan Statistical Area (MSA) with 9.4 million residents and a combined statistical area (CSA) with an estimated 2019 population of 9.83 million people. This metropolitan area spans 14 counties in Illinois, Indiana, and Wisconsin. The Chicago area is the third-largest urban area in the United States, following New York City and Los Angeles.

Kansas City Metropolitan Area

The Kansas City metropolitan area, anchored by Kansas City, Missouri, spans 14 counties straddling the borders of Missouri and Kansas. With over 2.1 million residents, it is the second-largest metropolitan area centered in Missouri, but the largest in Kansas. Suburbs with populations over 100,000 include Overland Park, Kansas; Kansas City, Kansas; Olathe, Kansas; Independence, Missouri; and Lee's Summit, Missouri.

Tucson Metropolitan Area

Tucson, Arizona, is a city with a population of 520,116 in the 2010 census and an estimated population of 980,263 in the 2015 census as part of the Tucson metropolitan statistical area. The Tucson MSA forms part of the larger Tucson-Nogales combined statistical area with a total population of 1,010,025 as of the 2010 Census. Tucson is the second most-populated city in Arizona, with Phoenix being the largest.

Great Falls Metropolitan Area

Great Falls, Montana, is the third-largest city in the state and the county seat of Cascade County. The city had a population of 58,505 in the 2010 census and was estimated at 58,434 in July 2019. Great Falls is the principal city of the Great Falls, Montana Metropolitan Statistical Area, which includes all of Cascade County. The total population stood at 81,327 in the 2010 census, while the largest metropolitan statistical area in Montana is the Billings metropolitan area with 1.08 million people.

These examples highlight the diversity and complexity of urban classification in the United States. Metros and CSA provide unique insights into the social and economic integration of different populations and regions.

Overall, understanding the definitions of urban population and metropolitan statistical areas is crucial for both researchers and policymakers. Definitions help in allocating funds and resources effectively, ensuring that the needs of urban and rural areas are met appropriately.

In conclusion, the distinction between the strict Census Bureau definitions and the popular cultural understanding of urban areas can provide valuable insights into the structure and dynamics of different urban regions. Recognizing how these areas are defined helps in formulating policies and programs that cater to the unique needs of metropolitan and suburban communities.
