Unit 2: population and demography APHG

Agricultural population density

Number of farmers per unit of arable land

Physiological population density

Population divided by the amount of arable land

Carrying capacity

Maximum number of a species that can live in an area without environmental deterioration

Arithmetic population density

Population divided by the total area

Population distribution

Extent to which people are spread out in an area

Ecumene

Inhabited land where humans live

5 toos

Hot, humid, dry, cold, and high climates

What are the densest regions of the world

East Asia, South Asia, Europe, Southeast Asia, and Northeast USA

Snowbirds

People who migrate to warm places during the winter for work or other reasons

- affects the population pyramid, distribution, and density

Coastal population clustering

Tendency for people to settle near coasts due to access to resources and trade

River population clustering

Tendency for people to settle near rivers due to access to water and transportation

Transportation population clustering

Tendency for people to settle near transportation hubs for ease of movement

High agricultural population density

Large number of farmers per unit of arable land

Low agricultural population density

Small number of farmers per unit of arable land (rich countries)

Rich, developed countries

Countries with high agricultural population density and more arable land, leading to high production

arable land

land capable of being used to grow crops.

why have india and china always had a high population

the land there is good for agriculture

where do people tend to cluster around

transportation areas, coasts, and rivers

what did thomas malthus believe

- there will be a population boom

- the population would outgrow food supply

based on Malthus's theory what type of growth would the population have?

J curve/exponential growth

how was Malthus wrong

food production has been able to keep up with the population

how do you calculate doubling time

divide 70 by the growth rate

what is a stable replacement rate

2.1

what stages are the countries of the world in today?

stage 2, 3, 4, and 5

what stage do women start to get rights

stage 3

where did stage 2 first occur

Europe - because of industrialization

factor that lowers the death rate

scientific discoveries

factor that lowers the birth rate

women's rights

what will happen to a stage 4 country if they do not accept immigrants

their population will decline

there will be a lot of old people

what does a high dependency rate indicate

there are a lot of old or young people in that country aka lots of dependents

what types of countries are in stage 5

smaller European countries

Japan

countries with a large old population

when does the death rate start to decline

stage 2

when does the birth rate start to decline

stage 3

what is the order of these terms

1) baby bust

2) baby boom

3) baby echo

baby boom, bust, echo

infant mortality rate

The percentage of children who die before their first birthday

- higher in poor countries than rich countries

birth rate

the number of births in a year for every 1,000 people in a population

fertility rate

the average amount of children per fertile woman

does the growth rate include immigration

yes

3 most populated countries

China, India, U.S.
