Anti-natalist Policy

Anti-natalist Policy

programs to decrease the number of births

Boserup theory

Crude Birth Rate (CBR)

the total number of live births in a year for every 1,000 people alive in the society

Crude Death Rate (CDR)

the total number of deaths in a year for every 1,000 people alive in the society

Demographic balancing equation

way geographers describe the future population of a region of any scale.

Demographic Momentum

process where even though fertility rates have declined, people are living longer which results in the population contining to grow for another 20-40 years.

Demographic Transition model

the process of change in a society's population from a condition of high crude birth and death rates and low rate of natural increase to a condition of low crude birth and death rates, low rate of natural increase, and higher total population

Doubling time

the number of years needed to double a population, assuming a constant rate of natural increase

Ecumene

the portion of Earth's surface occupied by permanent human settlement

Emigrants

people who move out of a country

Epidemiological Transition Model

distinctive cause of death in each stage of the demographic transition

Esther Boserup

Immigration

Neo-Malthusian

concerned that overpopulation may increase resource depletion or environmental degradation to a degree that is not sustainable with the potential of ecological collapse or other hazards; promote birth control and family planning

Population doubling time

time it takes for population to double in size.

Pro-natalist Policy

programs designed to increase the fertility rate

Rate of natural increase (RNI)

the percentage at which a country's population is growing or declining, without the impact of migration.

Thomas Malthus

British economist; noted that the world's population was increasing faster than the food supplies needed to sustain it

Total Fertility Rate (TFR)

the average number of children a woman will have throughout her childbearing years
