© 2013 Pearson Education, Inc. Sector Model According to the sector model, developed in 1939 by land economist Homer Hoyt, the city develops in a series of sectors. As a city grows, activities expand outward in a wedge, or sector, from the center.

Metropolitan Statistical Area The U.S. Bureau of the Census has created a method of measuring the functional area of a city, known as the metropolitan statistical area (MSA). An MSA includes the following: 1. An urbanized area of at least 50,000 inhabitants. 2. The county within which the city is located. 3. Adjacent counties with a high population density and a large percentage of residents working in the central city’s county.
© 2013 Pearson Education, Inc. Micropolitan Statistical Areas The census has also designated smaller urban areas as micropolitan statistical areas (μSAs). These include an urbanized area of between 10,000 and 50,000 inhabitants, the county in which it is found, and adjacent counties tied to the city.

© 2013 Pearson Education, Inc Suburban Sprawl In 1950, only 20 percent of Americans lived in suburbs. After more than a half-century of rapid suburban growth, 50 percent of Americans now live in suburbs. US suburbs are characterized by sprawl, which is the progressive spread of development over the landscape.

© 2013 Pearson Education, Inc Urban Transportation People do not travel aimlessly; their trips have a precise point of origin, destination, and purpose. Work related trips – 1/2 Shopping, social, and personal business – 1/4 Sprawl makes people more dependent on motor vehicles for access to work, shopping, and social activities.
© 2013 Pearson Education, Inc. Development of Urban Transportation Historically, people lived in crowded cities because they had to be within walking distance of shops and places of employment. Cities then built street railways (called trolleys, streetcars, or trams) and underground railways (subways) to accommodate commuters. These lines restricted suburban development to narrow ribbons within walking distance of the stations.
