Unit 2 Flashcards
Chapters 3.1-3.4 and 4.1-4.2 (24 cards)
Population distribution
Where people live
Climate
The long term patterns of weather in a particular area
EX: Usually warm weather along the equator
Human migration
The permanent movement of people from one place to another
Population density
The number of people occupying a unit of land
Arithmetic density
The total number of people per unit area of land
Physiological density
The total number of people per unit of arable land
Arable land
Land that can be used to grow crops (Farmland)
Agricultural density
The total number of farmers per unit of arable land
Subsistence agriculture
Farming to feed your family
EX: Growing crops in Minecraft
Carrying capacity
The max population size an environment can sustain
EX- There’s only enough water to support 3000 people, so only 3000 people can live there
Dependency ratio
People in a dependent age range (under 15 and over 65) divided by number of people in the working age group (15-24) multiplied by 100
Demographics
Data about the structures and characteristics of the human population
EX- Age, race, ethnicity, gender, martial status, etc
Crude birth rate (CBR)
Number of births in a given year per 1000 people in a given population
Total fertility rate
The average number of children one woman in a region will have during ages 15-49
Crude death rate (CDR)
The number of deaths in a given year per 1,000 people in a population
Infant mortality rate
The number of deaths of children under the age of 1 divided by 1,000 live births
Life expectancy
The average number of years a person is expected to live
EX: Cats life expectancy is 13-15 years old
Rate of natural increase
Rate a population grows as the result of the difference between the CBR and the CDR
Doubling time
The number of years in which a population growing at a certain rate would double
Urbanization
The growth and development of cities
Malthus’s theory
The world will grow exponentially and that food production wouldn’t keep up
Neo (New) Malthusian theory
Population growth is unsustainable and cannot be supported (Malthus theory part 2 basically)
Demographic Transition Model
Shows shifts in the growth of populations, based on trends related to CBR and CDR
Epidemiological Transition Model
Describes changes in fertility, mortality, and life expectancy (largely because of changes in causes of death)
