All Demography and Population Studies

Most of us find it most natural to understand and interact with people as individuals. This isn’t always feasible, though: when designing a political campaign or evaluating the success of a government program, when marketing a product to millions of people, or when studying a large-scale health issue, the population has to be seen as a statistical group.​Demography and population studies simply do this in a systematic way. Population growth, regional distribution and migration, education, health, and many other factors are studied. The resulting statistics guide economic forecasts, business planning, and public policy.​As a quantitative social science, population studies are inherently multidisciplinary. During a degree course, a student will typically come into contact with political science, sociology, economics, geography, and more.​Data may be gathered by surveys, from existing sources, and increasingly by using online resources. The latter has made it possible to separate populations far more granularly than ever before: instead of being restricted to basic parameters like gender, race, income level, and so on, marketers and planners now have access to a wealth of information on individuals. Processing this data statistically and garnering practically useful conclusions are part of the challenge of demography and population studies.
