2.5 Notes Demographic and Epidemic Transition Model

This is a replacement for the notes because there were just too many definitions to not do flashcards instead.

Demographic- Stage 1: Low Growth

High CBR- Cultural preferences, lack of contraceptives.

High CDR- Lack of medicine, animal attacks, war, and famine.

Low NIR.

Demographic- Stage 2: High Growth

High CBR- Industrial Revolution leads to food security.

Falling CDR- Increased medicine/ life expectancy with IMR.

High NIR

Demographic- Stage 3: Moderate Growth

Falling CBR- Women enter the workforce or are seeking education. There is also rising urbanization.

Falling CDR- Better medicine. Higher life expectancy. Falling IMR.

Moderate NIR

Demographic- Stage 4: Low Growth

Low CBR- Women delay marriage, seek education.

Low CDR- Higher incomes lead to better health outcomes.

No NIR. Zero population growth or falling.

Demographic- Stage 5: Negative Growth

Low CBR- Couples are choosing on to have kids.

Rising CDR- Increased urbanization and antibiotic resistant bacteria.

Negative population growth.

Epidemiological- Stage 1: Pestilence and Famine

Diseases, crop failure, and animal attacks.

Epidemiological- Stage 2: Receding Pandemics

Improved sanitation, better nutrition, food security, and medicine

Increased life expectancy, but pandemics are still a slight issue.

Epidemiological- Stage 3: Degenerative Diseases

Few Infectious deaths.

Longer life expectancies.

Rise in death from aging, cancer, strokes, and heart diseases.

Epidemiological- Stage 4: Delayed Degenerative and Lifestyle Disease

Medical advancements, better diets, reduced use of tobacco.

This is the countries life expectancy.

One problem in junk food and sedentary lifestyle.

Epidemiological- Stage 5: Reemergence of Infectious Diseases

Infectious and parasitic diseases may return with a resistance to antibiotics and mutations. This lowers life expectancy. There is rise in urbanization.
