Demography is the statistical study of human population. It may be a very general science applied to any kind of dynamic human population, namely, a population which changes over time and space -lrb - see population dynamics -rrb -. It involves the study of spatial and/or temporal changes in the context of size, structure and distribution of population and the study of birth, migration, age growth and death.
