Demographic Transition Stage characterized by declining population size

Post-industrial stage of the demographic transition, where declining birth and death rates result in a decreasing population size

Concept explaining population shrinkage despite replacement-level fertility

Population momentum, which is the continuation of population growth even after fertility rates fall below replacement level.

Society with low life expectancy and high birth rates

Transitional society, characterized by high birth rates and inadequate healthcare leading to a lower life expectancy.

Antinatalist pressure in industrialized nations

High economic cost of raising children.

Study Notes

Demographics

  • Demographics are statistical characteristics of a population, including age and income.

Infant Mortality Rate

  • Infant mortality rate is the number of infant deaths per 1,000 live births.

Replacement-Level Fertility Rate

  • Replacement-level fertility rate is 2.1, the rate needed for a stable population.

Total Fertility Rate

  • Total fertility rate is the average number of children a woman will have in her lifetime.

Factors Influencing Life Expectancy

  • Infant mortality rate significantly influences life expectancy.

GDP per Capita

  • GDP per capita represents the goods and services produced per person in a year.

Demographic Transition Stages

  • Pre-industrial stage: high birth and death rates.
  • Early transition: high birth rates, declining death rates.
  • Late transition: declining birth rates, low death rates.
  • Industrial: low birth and death rates.
  • Post-industrial: very low birth and death rates.

Population Growth Influences

  • Falling death rates lead to rapid population growth during the early transition stage of the demographic transition.

Immigration and Emigration

  • Immigration is the movement of people into a region.
  • Emigration is the movement of people out of a region.

Population Pyramids

  • Population pyramids with a wide base and narrow top indicate rapid population growth.
  • Population pyramids with an inverted triangle shape indicate negative growth.

Pronatalist Pressures

  • Pronatalist pressures are cultural and economic factors that increase birth rates.

Antinatalist Pressures

  • Antinatalist pressures are factors that decrease birth rates, often economic.

Key Economic Issues

  • Childcare expenses are a significant economic cost.

Geographic Regions

  • Mediterranean Basin refers to an area between Asia, Europe, and Africa.

Medical Advancements

  • Vaccines involve introducing weakened pathogens to build immunity.
  • Chlorination of water eliminated many waterborne illnesses.

Industrial Revolution Impacts

  • The Industrial Revolution saw the development of new methods for controlling waterborne diseases through medical advancements.

Population Control Methods

  • China's original population control policy involved limiting family size.
