Document Summary
Demography: the subfield of sociology that examines population size, composition, and distribution. Important because the nature of population affects all aspects of social life. Population: a group of people who live in a specified demographic area: changes in populations occur as a result of three processes: feritility (births), morality (deaths), and migration (movement from one place to another) Fertility: the actual level of childbearing for an individual or population. Biological factors affecting fertility: the number of woman of childbearing age (usually between 15 and 45)- primary factor, the health and level of nutrition of women of childbearing age. In some countries, government policies affect the fertility rate (china) Fertility rates have declined in most of the world, but in some low-income agricultural regions of the world, families have larger families, but with higher child mortality rates. Mortality: the incidence of death in a population: the primary cause of world population growth.
