Unit 2 (pt 1) Vocab Flashcards
Population distribution
the pattern of people scattered over an area
Population density
the number of people within a given area
World’s estimated population
7 billion
1/3 of the whole population is-
China (1.3 billion) and India (1.2 billion)
Where are the major population concentrations?
East Asia, Northeast America, South Asia, Western Europe
Where does 60% of the world’s population live?
Within 60 miles of the ocean
What do high populations have?
High soil fertility and mild climates
How is the world becoming more urban?
50% of the population is in urban areas
Human factors that influence population distribution
culture, economics, history, politics
Physical factors that influence population distribution
climate, land forms, water bodies
Ecumene
the habitable parts of the world
Factors the show population distribution vary by scale of analysis
eg. Migration- global regional national local
population density- name 3 methods
measure of total population relative to land size
- arithmetic
- physiologic
- agricultural
Arithmetic population density
measure of the number of people within a given area divided by the total land area
Physiologic population density
measure the number of people per arable (farmable) land
agricultural population density
measure of the number of farmers per arable land
Political processes
more laws, greater power/influence
Economic processes
more jobs, higher tax base, increase in poverty
Social processes
more education, more health care, greater diversity (language/culture)
Pop. dis affect environment
deforestation, less spave/room, pollution, natural resource depletion
patterns of age and gender vary across scales
ratio global regional national local
population pyramids
provides a visual representation of a population in terms of age and sex as well as a good indication of the dependency ratio within a country and is used to assess population growth and decline and to predict markets for goods/services
Least developed countries (LDC) tend to…
have pop pyramids predicting rapid growth
More developed countries (MDC) tend to…
have pop pyramids stable or declining
