Option 3 : Demography

Demography is the study of human populations – their size, composition and distribution across space – and the process through which populations change. Births, deaths and migration are the ‘big three’ of demography, jointly producing population stability or change.

  • Demographic transition refers to a historical shift from high birth and death rates to low birth and death rates with advanced technology, education and economic development. 
  • The 5 stages of demographic transition are-
    • Stage 1 - low population and balanced birth and death rate.
    • Stage 2 - Population rises, Birth rate increases and death rate falls.
    • Stage 3 - The gap between Birth and death will keep getting narrower.
    • Stage 4 - Population growth is slow but the population is high. Low birth and low death rate.
    • Stage 5 - The population starts declining, nevertheless the population is still very high.
