What is element of demography​

Demography is the statistical study of human populations. It includes the study of the size, structure, and distributions of different populations and changes in them in response to birth, migration, aging, and death.

Demographics can include any statistical factors that influence population growth or decline, but several parameters are particularly important: population size, density, age structure, fecundity (birth rates), mortality (death rates), and sex ratio (Dodge 2006). We introduce each of these in turn.
