Unit 2 Review

Population Growth/Decline

100

CBR-CDR/10 

Natural increase rate, rate of natural increase 

200

Graph that shows a boom in population starting around 1750. 

J-Curve 

300

Population pyramid that has more elderly people, compared to younger people.

Shrinking Population 

400

Little to no education/work opportunities for women, lack of access to contraceptives, babies often to not survive long so women tend to have more in hopes they will survive. 

Reasons for high birth rate 

500

Good health care system, less diseases/pandemics/epidemics, systems in place to care for the elderly, high life expectancy

Reasons for low death rate 

DTM

100

There are no countries currently in this stage of the DTM 

Stage 1 

200

This stage has a high birth rate, a high death rate, that begins to decline, rapid population growth, and a heavy youth dependency 

Stage 2

300

this stage has a falling birth rate, and a falling death rate, the population is increasing but not as fast.

Stage 3

400

Reasons why a country might be in stage 4 of the DTM. 

Low CBR, and CDR, high life expectancy, population growth is more stable. 

500

Problems countries in stage 5 of the DTM might experience. 

Small work force, high dependency ratio due to elderly dependency, higher taxes to support social security

Population Basics

100

The number of live births per 1000 people 

Crude Birth Rate 

200

This calculation shows the carrying capacity of an area, or how mush people the resources in an area can support. 

Physiological Density 

300

Large amount of babies do not survive past the age of 1, due to poor health care systems for women and children. 

High infant mortality rate 

400

When a country is an LDC, has a low level of technology, most of the farming is done by hand so there are more farmers, and there is less food output. 

High Agricultural Density 

500

This type of country has a High birth and death rates, high IMR, high population growth rates, low life expectancy, and a high dependency ratio due to a lot of children. 

Less Developed Country 

Population Policies/Theories

100

Policy that promotes people to have more children. 

Pro-natalist policy 

200

Ex: China's one child policy

Anti-natalist policy 

300

This person believed that the earth's population and food supply were growing at different rates, and that we would eventually run out of food to support the population. 

Thomas Malthus 

400

Certain factors have slowed population growth, there are new technologies that have increased efficiency of farming, and there are more ways to preserve food for longer. 

Criticisms of Malthusian theory 

500

This theory believes that while the world probably won't run out of food, we still need to be cautious about using the earth's resources. 

Neo-malthusian theory 

Migration

100

Moving into a new country or area.

Immigration 

200

Moving out of a country or area. 

Emigration 

300

Natural disasters, war, persecution, diseases, and famine. 

Push Factors 

400

Jose decided to leave Honduras for a better life. He first goes to Guatemala for a few weeks with family, and then stays in Mexico for a month for work. Then he ends up in the United States living with family.

500
