Total Fertility Rate (TFR)
The average number of children a woman will have during her childbearing years.
Birth Rate
Number of live births in a single year for every 1000 people in a population.
Replacement Fertility Level
Stands at 2.1, slightly higher than 2.0 to account for infant/childhood mortality and childless women.
Mortality Rate

Natural Increase
Birth rate minus death rate.
Population Doubling Time
The length of time for a population to double in size.
Demographic Transition Model - Stage 1
Pre-industrialization stage with high birth and death rates leading to low population growth.
Demographic Transition Model - Stage 2
Developing country stage with high birth rates and decreasing death rates, leading to population increase.
Demographic Transition Model - Stage 3
Developing country stage with dropping birth rates and death rates, stabilizing the population.
Demographic Transition Model - Stage 4
Developed country stage with low birth and death rates, resulting in a stable population.
Demographic Transition Model - Stage 5
Developed country stage with very low birth rates and low death rates, leading to a declining population.
Epidemiologic Transition
Increase in population due to medical innovation causing a decrease in the death rate.
Population Explosion
The significant and continuing increase in human population in modern times.
Thomas Malthus (1798)

Ester Boserup (1965)

Ravenstein's Laws of Migration (1885)
Every migration flow generates a return flow - Most migrants move short distances - Longer distance migrants tend to choose big cities - Most migrants are from rural areas - Economic reasons drive migration.

Aging Index
The number of people age 65 and over in a population.
Aging Population
Increasing median age due to declining fertility/rising life expectancy
Social Consequences
Impact on family life and elder care provision
Economic Consequences
