DEMOGRAPHY DIVISION




The word Demography has been derived from the Greek words ‘Demos’ and ‘Graphy’ which mean 'Population' and ‘Science’. Thus, demography is the scientific study of human population. The three components of population change viz. (i) Birth (ii) Death and (iii) Migration are core to the domain of population studies. Demography also deals with associated social factors such as age, sex, marital status, occupation, literacy etc. for enabling a holistic understanding of demographic change.

The Demography Division is primarily responsible for undertaking analytical/ technical studies on fertility, mortality and migration using Census data. Another very important responsibility of the Division is working out the projections of population on behalf of the Technical Group on Population Projections constituted by the Government of India. The latest population projections made by the Technical Group on Population Projections based on the Census of 2011 can be accessed here. The main areas of work of the Demography Division of the ORGI are listed below:
