Early Cities:
prerequisites for development


Early cities were quite small by our standards.

urban form:
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:
cities that were deliberately established or developed as administrative or commercial centers by colonial or imperial powers.

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

economic base:
set of manufacturing, processing, trading, or services activities that serve markets beyond the city.
These activities bring a net flow of income into the city.

basic functions:
economic activities that provide income from sales to customers beyond city limits.

nonbasic functions:
economic activities that serve a city's own population.

Emergence of the modern city:

industrial city:
functions to assemble raw materials, and to fabricate, assemble, and distribute manufactured goods.

city that is seen as the embodiment of surprising and disturbing changes in economic, social, and cultural life.

the way of life, attitudes, values, and patterns of behavior fostered by urban settings.


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

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.

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.

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.

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

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

What are the assumptions of the model? How do these assumptions simplify reality and for what purpose?
