Expansive population policies Government policies designed to encourage large families and raise the rate of population growth.
Genetic or inherited diseases Diseases caused by variation or mutation of a gene or group of genes in humans.

Population composition Structure of a population in terms of age, sex, and other properties such as marital status and education.
Population density Number of people per unit area of land.
Population distribution Description of spatial distribution of people, including where large numbers of people live closely together and where few people live.
Population pyramids A graphic representation of the age and sex composition of a population.
Restrictive population policies Government policies designed to reduce the rate of natural population increase (also called antinatalist).
Total fertility rate (TFR) The average number of children born to a woman of child-bearing age.
