2.1 and 2.2 Flashcards
What are the four major population clusters?
South Asia
SouthEast Asia
East Asia
Europe
What is Eurasia
Europe and Asia combined
Ecumenism
Lands that are habitable
Population clusters
Heavily populated areas which show the unevenness of population
Metacity
20 million or more people
Megacity
10-19 million people
Developed countries
Fully industrialized countries / advanced economies
Developing country
Economically poorer than developed countries
Snow belt
Northern and midwestern parts of land
Sunbelt
Coastal and south and south western parts of land
Mean center of population
Balancing point/middle point of the population
Population density
Average # of people per unit of land
Arithmetic (crude) density
How populated a unit of land is
What do empty quarters show
Empty quarters show the patterns on why people dont live there
Reasons that effect where we live
Landforms, climate(latitude), culture, disease, economic richness, elevation, fertile soil, and bodies of water
Where do people not settle
Too hot, cold, wet, hilly, dry
Population Composition
Makeup of the population by age, sex, ethnicity, income, and education
What does population composition effect
Effects rate of birth, death and migration
Age structure
Breakdown of a population into different age groups
Dependency ratio
The number of dependents in a population which shows every 100 people must care for
Youth dependency ratio
Number of people under 15 who can’t care for themselves
Elderly dependency ratio
Number of people above 64 who can’t care for themselves and must be supported
What is the equation for the dependency ratio?
Youth+Elderly divided by the number of working people
Generations
Groups of people who were born around the same time and share common traits because of how they grew up culturally
GI Generation
Oldest generation in America 1924 fought in the war
Silent Generation
1924-1945, lived in the Great Depression, small because there weren’t very many births
Baby Boomers
1946-1964, post World War Two birthday that skyrocketed
Gen X:
1965-1980, they are in the Prime working years
Millennials
1981-2000, fight for political rights, in a lot of debt
Gen Z
My generation, too early to tell the common traits
Sex ratio
Males to every 100 women in a population
Androcentrism
A Culture that demonstrates a preference for males
Infanticide
The practice of killing infants
Pop pyramids
Comparing age and sex structure
Rapid growth pyramids
Wide base, birth rates are high, elderly don’t live as long
Slow growth pyramids
Birth rate is just over death rate, narrow base but still a pyramid shape
Stability pyramid
Birth rate is similar the the death rate, looks like a pillar
Decline pyramid
Narrow base, too heavy, labor shortage
An effect of Gender selective migration
Causes gender imbalances
Who are the dependent people
People 15> and 64<
What does arithmetic population density show
Represents how many people live per sq mile
Physiological population density
Shows how many people depend on an area of land for food
What is agricultural density
Shows the amount of farmers per arable land which shows the economic development of a country
What does a high number of agricultural density mean?
The country is not very industrialized
ESPN - consequences of population distribution
Economic
Social
Political
Natural Resources
Economic reasons for population distribution
Job opportunities
Natural resources available
Social/cultural reasons of population distribution
Housing, religion, safer, transportation; community
Environmental reasons of population distribution
Maximum population size an environment can sustain
High population density would mean more pressure on resources
What does it mean when a country has lower wages
It it less developed or industrialized
What so the equation for arithmetic population density
Total pop
________\____
Land area
Equation for physiological population density
Total Pop
___________
Arable land
Equation for agricultural density
Farmers
___________
Arable land
