Economies: Centrality is defined as the most accessible location with Cities initially grew up at focal points to adjacent population resided respect to a surrounding population. within the settlement itself, while other people resided in agrarian Agglomeration: the clustering of similar or dissimilar economic, social, locations outside the central city. The essential function of the CBD was cultural, and governmental activities in a given location—the CBD and later to perform services not only for the surrounding city, but also for the suburban business locations. Two types of agglomeration: adjacent agricultural region. Localization economies result when similar activities cluster. Urbanization economies refer to clusters of unlike activities. The Development of Central Business Districts: CBD’s initially sprang up in four general kinds of locations: (1) Break-of-bulk points. (2) Along transportation routs, rail lines. (3) Special function locations, mining and tourist resorts. (4) Market place, central city serving surrounding areas. www.donaldpoland.com 7 www.donaldpoland.com 8 2 Urban Land Use: The CBD and the Growth of the Suburbs Urban Land Use: The CBD and the Growth of the Suburbs CBD - Centrality Traditional CBD Characteristics CBD Agglomeration Linkages: Four kinds of agglomeration linkages are The monocentric city was the place important in understanding localization and urbanization economies in the where virtually all people worked, CBD, especially after 1960. shopped, obtained consumer and professional services, and sought Ancillary linkages: unlike activities to serve a mutual market. out cultural events and Competitive linkages: savings derived when several different and unlike entertainment.

This zone is typically found in one of traditional monocentric CBD, but also characteristic of the modern two locations: (1) expansion often polycentric metropolitan area, are the marked changes in CBD occurs in the direction that is closest to higher income residential population density during 24-hour weekday period. areas. (2) the zone of assimilation In 1950, very few people lived in the CBD core. Only a slightly few commonly expands into a former zone of discard. more lived in the CBD frame. The nightlife population was sparse. Nighttime population would peak in density 1 to 3 miles from the CBD. The zone of discard is an older and decaying edge of a formerly The daytime and working population densities have also changed since vibrant part of the CBD that has declined.

The shopping malls in the early developing jobs declined in central-city locations. Residents and retailers started to suburbs initiated the demise of the downtown retailing. Today, except in relocate to suburban malls and safe communities with newer and more subway-oriented rapid transit centers such as New York and Toronto, spacious homes with yards. CBD retailing has become essentially restricted to three basic types: By the 1960s, CBDs has declined significantly as the areas became Mass-appeal consumer goods: serve a captive market made up associated with high crime rates, vacant stores, homeless people, primarily of nearby inner-city residents, some of whom are welfare- marginal businesses, downscale merchandise, and low-quality dependent.
