Demography (journal)

Demography is a type of journal that studies people - how many people there are in a particular place, how fast their population is growing, the age of the population, what kind of jobs they do, how much money they make, etc. Demographic research can be used by governments and businesses to figure out what issues they need to deal with and how to best meet the needs of the people who live there.
