Demography
Demography is the statistical study of human populations. It can be a very general science that can be applied to any kind of dynamic living population, i.e. , one that changes over time or space. It encompasses the study of the size, structure, and distribution of these populations, and spatial and/or temporal changes in them in response to birth, migration, aging and death. “Demo” means “the people” and “graphy” means “measurement”.
