Laws of Migration

Most migration is due to economic causes
Most migration is over a short distance, and often occurs in steps
Long-range migrants usually move to urban areas
Each migration produces a movement in the opposite direction (every action has an equal and opposite reaction)
Rural dwellers are more migratory than urban dwellers
Within their own country females are more migratory than males; Males are more migratory over long distances
Most migrants are adults

Gravity Model

Shows that interaction is proportional to the multiplication of the two populations divided by the distance between them; this phenomenon is distance decay (the effect of distance on cultural or spatial interactions)

Thomas Malthus

(Person)Gave a dystopian view of the future (1798); Food production increases arithmetically, whereas human reproduction increases geometrically (doubling each generation); despite checks on population, there would continue to be starvation.

The Demographic Transition Model

A model used to represent the process of explaining the transformation from a pre-industrial to an industrialized economy. It has 4 definitive stages:
In stage one (high stationary), pre-industrial society, death rates and birth rates are high and roughly in balance.
In stage two (early expanding), that of a developing country, the death rates drop rapidly due to improvements in food supply and sanitation, but without a corresponding fall in birth rates this produces an imbalance, resulting in a large increase in population.
In stage three (late expanding), birth rates fall due to access to contraception, increases in wages, urbanization, a reduction in subsistence agriculture, an increase in the status and education of women, a reduction in the value of children's work, an increase in parental investment in the education of children and other social changes. Population growth slows.
In stage four (low stationary) there are both low birth rates and low death rates due to the expansion of wealth and technology.
"Stage five" (hypothetical), birth rates may drop to well below replacement level as has happened in countries like Germany, Italy, and Japan, leading to a shrinking population. This may be a threat to many industries that rely on population growth, and would likely create an economic burden on the shrinking working population.

The Epidemiological Transition

Occurs as a country modernizes. Developments in medicine (e.g., antibiotics such as penicillin), drastically reduces mortality rates and extends life expectancy. Further development and urbanization results in declining fertility rates, and a transition to chronic and degenerative diseases as more likely causes of death. This occurs in three phases:
1. Age of Pestilence and Famine: mortality is high and fluctuating (low population growth); low and variable life expectancy (20 to 40 years)
2. Age of Receding Pandemics: mortality progressively declines; average life expectancy increases steadily (30 to 50 years); population growth begins to be exponential
3. Age of Degenerative and Man-Made Diseases: mortality continues to decline and eventually approaches stability at a relatively low level

The Isolated State Model

Discussed agricultural location as primarily a factor of transportation cost and profit maximization by farmers through his model. For the image to the left - the black dot represents a city; 1 (white) dairy and market gardening; 2 (green) forest for fuel and building materials; 3 (yellow) grains and field crops; 4 (red) ranching; the outer, dark green area represents wilderness where agriculture is not profitable.


Created the Concentric Zone Model.
His work is based on bid-rent (the amount that people will pay for the land) (Ex: wealthier families tended to live much further away from the CBD because they could afford automobiles)

The Concentric Zone Model

Structural model of the American central city (based on Chicago in the 1920s); the zones identified are:
1) the central business district (CBD);
2) the transition zone of mixed residential, factory, and commercial use (low residential density);
3) low-class residential homes (the "inner city" with high residential density);
4) better quality middle-class homes (with lower density than the previous zone)
5) upper-class commuters zone (with the lowest density)


(Person) Created the Sector Model

The Sector Model

Improvements in transportation made the Burgess Model more obsolete. Hoyt (the creator of this model) observed that zones expanded outward from the city center along electric trolley lines, railroads, highways, and other transportation arteries; wedge-shaped patterns -- or sectors -- emanating from the CBD and centered on major transportation routes.


Created the Central Place Theory (Person)

The Central Place Theory

Designed to explain the spatial distribution of human settlements. Central places are settlements providing services to their surrounding "market areas". The ordering of settlements based on the number and level of services they provide produces a hierarchy. Hierarchies are often complicated because market areas of different-order settlements overlap (shown as solid and broken lines).
The theory relied on two main concepts:
Threshold - the minimum market needed to bring about the selling of a good or service.
Range - the maximum distance people will travel to acquire the good or service.
Four generalizations can be made regarding the spacing, size and function of settlements. The greater the size of the central place:
1. the fewer they are in number;
2. the greater the distance between them;
3. the greater the number and range of functions;
4. the greater the number of higher-order services (e.g., arenas, universities, museums, zoos, etc.)


Created the Least Cost Theory (Person)

The Least Cost Theory

A variable cost analysis emphasizing the motive of manufacturing plants to pursue cost minimization along three areas: 1) transportation, 2) labor, and 3) agglomeration (too much can lead to high rents and wages, circulation problems - and ultimately to deglomeration); in the weight-losing case, firms locate closer to the raw materials to reduce cost (e.g., metal smelting, paper products); in the weight-gaining case, firms locate closer to the market (e.g., bottling, bread products).


Introduced the Modernization Model (Person)

The Modernization Model

A liberal model (stating that all states may develop in the sane way); postulates that economic modernization occurs in five basic stages:
1) Traditional society - economy focuses on mostly subsistence or primary-based activities; society is rigid, negatively viewing change
2) Preconditions for takeoff - development of more productive commercial and cash crops, increased investment and technology; social mobility begins as elite promote change
3) Takeoff - a critical mass of resource exploitation, labor, and capital propel the society toward secondary activities with a few leading industries; export-oriented
4) Drive to Maturity - diversification of industries shift to more domestic consumption; rapid development of transportation and social infrastructure (e.g., bridges and schools)
5) Age of Mass Consumption - modernization and urbanization diffuses throughout the country; industrialization dominates, but a rise in tertiary (and quaternary and quinary) activities results; most have disposable income beyond basic needs (e.g., automobiles)


Introduced the 3 tiered World-Systems Analysis (Person)

The World Systems Analysis

A three-tiered structuralist model (stating that regional disparities are the result of historically derived power relations within the global economic and political system, and therefore cannot be changed easily).

It postulates a "one-world" economic and political framework (not focusing on the independent economies of nation-states). The global division of labor consists of one economy divided between the "core" (most developed countries (MDCs) - e.g., US, UK, Japan) which dominates other countries; the "semi-periphery" (Newly Industrialized Countries (NICs) - e.g., Brazil, China, India) which is dominated (by the core) while at the same time dominating others (the periphery); and the "periphery" (Least Developed Countries (LDCs) - e.g., Congo, Zambia, Haiti) which is dominated due to dependency on the more powerful global economies.

The Multiple Nuclei Model

Based on the idea that people have greater movement due to increased car ownership. This increase of movement reduced the primacy of the CBD and allowed for the specialization of regional centers (e.g., nuclei such as light manufacturing, business parks, residential areas, etc.).

The Peripheral Model

The US urban area consists of an inner city surrounded by large suburban residential and business areas tied together by transportation nodes (e.g., a beltway or ring road to avoid traffic congestion). The periphery acts as a functional metropolitan complex, not a series of separate CBDs. It represents urban decentralization (with an increase in edge cities) and the US transcendence into a post-industrial society (from predominantly secondary economic activities to tertiary, quaternary, and quinary activities).
