what is demography

Demography is the systematic study of the population of a country, area, community, etc. The term is of Greek origin and is composed of the two words, demos (people) and graphein (describe).

Demography studies the trends and processes associated with population including – changes in population size; patterns of births, deaths, and migration; and the structure and composition of the population, such as the relative proportions of women, men and different age groups.

There are two types of demography:

1. Formal Demography: statistical analysis of population i.e., total population, number of males, number of females, number of youth, working population, rural urban (quantitative data)
2. Social Demography: birth rate, death rate and migration that happens in a particular society.
