Q:

Why is demography important?

A:

The importance of demography lies in its contribution to helping government and society better prepare to deal for the issues and demands of population growth, aging and migration. The statistics and predictions resulting from demographic studies can, for example, aid in the development of adequate school systems, estimate the required funding for senior services and develop workable healthcare systems. A wide variety of social outcomes are impacted by demographic processes and distributions.

The analyses derived from demographic studies rely upon a specialized set of models and methods, including population composition studies, life table analysis, simulation and mathematical models, survival analysis and ratios. Demography lies at the crossroads of several other disciplines, including economics, sociology and epidemiology.
