prerequisites for development

the physical structure and organization of cities.

Problems limiting the growth of early cities:

Early city functions:

Locational patterns and functions of American cities:
 


colonial cities:

gateway city:
city that serves as a link between one country or region and others because of its physical situation.

economic base:

These activities bring a net flow of income into the city.

urban system:
an interdependent set of urban settlements within a specified region.


centrality:
the functional dominance of cities within an urban system.

world city:
cities in which a disproportionate part of the world's most important business is conducted.

primacy:
condition in which the population of the largest city in an urban system is disproportionately large in relation to the second and third largest cities in that system.

rank-size rule:
a statistical regularity in city size distributions of cities and regions.

megacity:
very large city characterized by both primacy and has high centrality within its national economy.

central place:
a settlement in which certain products and services are available to customers.

central place theory:
a theory that seeks to explain the relative size and spacing of towns and cities as a function of people's shopping behavior.

range:
the maximum distance that consumers will normally travel to obtain a particular product or service.

threshold:
the minimum market size required to make the sale of a particular product or service profitable.
