The fact that most Americans live in
urban areas does not mean that they {{U}}reside{{/U}} in the center of large cities.
In fact, more Americans live in the suburbs of large metropolitan areas than in
the cities themselves. The Bureau of the Census regards any
area with more than 2,500 people as an urban area, and does not consider
boundaries of cities and suburbs. According to the Bureau, the
political boundaries are less significant than the social and economic
relationships and the transportation and communication systems that
{{U}}integrate{{/U}} a locale. The term used by the Bureau for an integrated
metropolis is an MSA, which stands for Metropolitan Statistical Area. In
general, an MSA is any area that contains a city and its surrounding suburbs and
has a total population of 50,000 or more. At the present time,
the Bureau reports more than 280 MSAs, which together account for 75 percent of
the US population. In addition, the Bureau recognizes 18 megapolises, that is,
continuous {{U}}adjacent{{/U}} metropolitan areas. One of the most obvious
megapolises includes a chain of hundreds of cities and suburbs across 10 states
on the East Coast from Massachusetts to Virginia, including Boston, New York,
and Washington, D.C. In the Eastern Corridor; as it is called, a population of
45 million inhabitants is concentrated. Another megapolis that is growing
rapidly is the California coast from San Francisco through Los Angeles to San
Diego.
