Demography, Defined
Captions available
The idea
Demography is the study of populations, using fertility, mortality, and migration to describe how a population's size and composition change over time.
In practice
A national census office reconstructing a country's postwar population trajectory from birth, death, and migration records illustrates demography's method.
Where people slip
Demography studies population-level patterns; it does not predict any individual's birth, death, or migration decision.
