City-State

Consisted of an urban center (the city) and its surrounding territory and agricultural villages.

Urban Hearth

Early city-states emerged in several locations around the globe in this form. It's an area generally associated with defensible sites and river valleys in which seasonal floods and fertile soild allowed for an agricultural surplus.

Had important effects on the urban structure leading to a decline in pedestrian cities.

Pedestrian Cities

Are the earliest urban centers, cities shaped by the distances people could walk

Streetcar Suburbs

Communities that grew up along rail lines, emerged, often creating a pinwheel shaped city.

Communications impacts on cities

Had dramatic impacts on the growth and development of cities. Cities connected to trade routes received information first.

Population and migration impacts on cities

Population growth pressure, cultural tension, environmental strain, and lack of economic opportunities created puch factors in agricultural communities.

Economic development and government policies impact on cities

Cities are now viewed as engines of growth for a country's economy. Consequently, economic and political leaders, at the national and local scale, develop policies to guide and encourage the growth of cities.China implemented the new urbanization plan. Cities in the Midwest of the United States, such as Cleveland, Pittsburgh, and Chicago, were often focused on attracting manufacturing jobs; while cities in Florida, such as Orlando and Tampa , promoted development based retirement and tourism.

A term for the early 1900's that describe a chain of connected cities.

Conurbation

An uninterrupted urban area made of towns, suburbs, and cities.

Trend of urbanization in the developing world

The pattern has changed unlike in the past century where megacities were found at centers of large empires or the most powerful countries, they have now become more common in LDCs.

World Cities (Global Cities)

Cities that exert influence far beyond the national boundaries. Cities like New York, London, Tokyo, and Paris.

Urban Hierarchy

Ranking, based on influence or population size.

Top 10 World Cities 2020

London, New York City, Tokyo, Paris, Singapore, Amsterdam, Berlin, Seoul, Hong Kong, Shanghai.

Nodal Cities

Command centers on a regional and occassionally nation level.

Urban Systems

An interdependent set of cities that interact on the regional, national, and global scale.

Rank-size Rule

Describes one way in which the sizes of cities within a region may develop.

High-order Services

Usually expensive, need a larger number of people to support, and are only occassionally utilized.

Low-order Services

Usually less expensive, require a small population to support, and are used on a daily or weekly basis.

Primate Cities

Is more developed than other cities in the system, and consequency, disproportionately more powerful.

Gravity Model

States that larger and closer places will have more interactions than places that are smaller and farther from each other.

Central Place Theory (CPT)

Is used to explain the distribution of cities of different sizes across a region.

Central Place

A location where people go to recieve goods and services.

Market Area

A zone that contains people who will purchase goods or services, surrounds each central place.

Hinterland

The outlying towns and small communities that rely on the central city for goods and services.

Threshold

The size of population necessary for any particular service to exist and remain profitable.

Range

The distance people will travel to obtain specific goods or services.

Limitations of CPT

Assumes a flat, featureless plain. It does not take into account the effects of natural landscapes of rivers, mountains, or other barriers on the distribution of cities.

Expected changed in US cities by 2040

As millenials have started families, they have relocated out of central cities into enclaves inspired by new urbanist designs. In the future, self-driving cars and other new technology could reduce the friction of distance. Voluntary segregation will likely continue, and the number of ethnic neighborhoods will flourish.

Expected changes in megacities in Asia and Africa by 2040.

The economic, social, and educational opportunities these cities offer will continue to pull in migration from rural areas. If growth exceeds carrying capacity, the standard of living will deteriorate. The increasigly dense concentration of people will increase the impacts of deadly epidemics, natural disasters, etc.

Function of Urban Models (3)

Concentric zone, sector, and multiple nuclei models.

Functional Zonation

The idea that portions of an urban area-regions, or zones, within the city-have a specific and distinct purposes.
