-
Population Geography
-Provides the background concepts and theories
-forecast the size, composition, and distribution of the human population.
-
Demography
Statistical study of human population
-
Why does population geography differ from demography?
-Because of its concern with spatial analysis
- location, density, pattern, and relationship to the physical environment
-
Rates (Demographers convert counts to rates)
- -Record the frequency of occurrence of an event
- -during a given time frame for a designated population
Ex: Marriage rate per 1,000 in the US
-
Cohorts (birth rates, death rates, etc.)
Population group unified by a specified temporal characteristic
Ex: Age cohort of 0-4 years
-
Crude Birth Rate
Annual number of live births per 1000 population
Birth rates of less than 18 per thousand are characterized as low
- Developed countries- 11 is the average
- Less developed- 25 is the average
-
Transitional Birth Rates
Between 18 and 30 per 1,000
Characteristic of developing countries
-
Total Fertility Rate
- -Average number of children born to woman during childbearing years
- -If she bore children at current year's rate for her age
- -More accurate than crude birth rate because it does not account for people who cannot reproduce
-
Replacement level fertility
-2.1 or 2.3, not 2.0 because you need to account for infant and childhood mortalities
-Amount of fertility to replace population (higher in low-income, developing countries)
-
Crude Death Rate (mortality rate)
Infant Mortality Rate
-Annual number of deaths per 1,000 people
Affected by a population's age distribution (elderly have a higher crude death rate)
Ratio of deaths of infants aged 1 year or under per 1,000 live births
-
Population Pyramid
-Means of visualizing and comparing
-population's age and sex composition
-
Dependency Ratio
- -A simple measure of the number of economic dependents
- -each 100 people in the productive years must support
-
Rate of Natural Increase
- -Subtract crude death rate from crude birth rate
- -Natural-increases due to migration are not included
Expressed as a percentage
-
Doubling Time
-Time it takes for a population to double if the present growth rate remains constant
-Use the rule of 70: Divide 70 by the growth rate to find doubling time
Dubious because they are based on assumptions
-
-
Demographic Transition Model
- -Model traces the changing levels of human fertility and mortality
- -industrialization, health care improvements, urbanization, and changing cultural attitudes regarding childbearing.
-
Stages of Demographic Transition
(4)
- 1) High birth and high (but fluctuating) death rates, slow population growth
- 2) Rapid population growth as birthrates outstrip death rates
- 3) Birth rates decline as people begin to control family size
- 4) Very low, nearly equal birth and death rates (aging)
-
Epidemiological Transition
-Formerly fatal epidemic diseases
-Became endemic
-
Demographic equation
- -Summarizes the contribution made to regional population change over time
- -combination of natural change (births minus deaths) and net migration (difference between in-migration and out-migration)
-
Zero Population Growth
-Condition for individual countries
-Births+Immigration=Deaths+Emigration
-
Ecumene
-Permanently inhabited areas of the earth's surface
Ex: City
-
Nonecumene
-Uninhabited
-Or very sparsely occupied zone
Ex: Permanent ice caps
-
Population density
-Relationship between number of inhabitants and area they occupy
-
Crude density (arithmetic density)
-Calculates the number of people per unit area of land
-Usually within areas of political entity
-
Physiological Density
- -Measure of population pressure exerted on agricultural land
- -Total population divided by arable land area
-
Agricultural Density
-Reports number of residents per area of agriculturally productive land
-Excludes city populations from physiological density population calculation
-
Overpopulation
-An environment cannot support its present population
-
Food Security
-Having access to safe and nutritious food
-Meet individual dietary needs with cultural preference
-
Population Projections
-Estimates
-future population size, age, and sex composition based on current data.

-
Agglomeration
- -Clustering of productive activities and people
- -For mutual advantage
-
Weber's Five Assumptions
- 1. An area is completely uniform physically, politically, culturally, and technologically. Uniform or isotropic assumption
- 2. Manufacturing involves a single product to be shipped to a single market in a known location
- 3. Inputs involve raw materials from more than one known source location
- 4. Labor is infinitely available but not immobile
- 5. Transportation routes are not fixed but connect origin and destination by the shortest path; and transport costs directly reflect the weight of items shipped and the distance moved
-
Substitution Principle
In many industrial processes it is possible to replace a declining amount of one input with an increase in another or to increase transportation costs while simultaneously reducing land rent

-
Deglomeration

Ex: Relocation of firms to nonmetropolitan areas
-
"Fordism"
Flexible Manufacturing

Flexible Production Systems

Smaller production runs of a great variety of goods aimed at a smaller market
Seeks to reduce inventories by purchasing inputs for arrival just in time to use and producing output just in time to sell
Ability to move from one factory process to another as market demand dictates
-
Comparative Advantage
