Study Notes
Demographic Transition
- Demographic transition is a model that describes changes in a country's population, from high birth rates and high death rates to low birth rates and low death rates, eventually stabilizing the population.
- This stabilization often occurs in industrialized countries, with less developed countries following the advancements of more developed countries.
Growth Rate
- Growth rate measures how much a country's population grows or shrinks over a time period.
- It is calculated by adding the number of births and immigrants, and subtracting the number of deaths and emigrants.
Factors Influencing Population Growth
- Economic benefits: children can work to support the family.
- Government incentives: some countries provide incentives for families to have more children, such as Japan.
- Religious influences: some religions promote large families, and may even forbid the use of contraceptives.
- Cultural influences: having children means passing down family traits and values, and is seen as a source of prestige.
Demographic Transition Model
- Stage 1: high birth rates and high death rates, due to limited birth control and economic benefits of having more people to work.
- Stage 2: death rates drop due to improvements in health and sanitation, leading to population growth.
- Stage 3: birth rates also begin to fall due to access to contraception and a changing social trend toward smaller families.
- Stage 4: population stabilizes, with low birth rates and death rates balancing each other out.
- Stage 5: (speculation) population may stabilize, decrease, or increase, depending on factors such as resource availability and individualism.
Population Pyramids
- Stage 1: high stationary population pyramid, with a large young population and a small older population.
- Stage 2: early expanding population pyramid, with high birth rates and declining death rates.
- Stage 3: late expanding population pyramid, with declining birth rates and death rates.
- Stage 4: low stationary population pyramid, with low birth rates and death rates, and a longer life expectancy.
- Stage 5: constrictive population pyramid (speculation), with fewer young people than old, or a growing population pyramid, depending on the factors mentioned above.

Description
The demographic transition model describes how a country's population changes from high birth and death rates to low rates, stabilizing the population, typically in industrialized countries.
