Important Facts

  • 1911–1921 showed negative growth due to rapid and frequent occurrence of epidemics like cholera, plague, influenza and famines.
  • 1921- “Year of great divide” because India entered into the 2nd stage of demographic transition and the population of India exploded. Birth rate and death rate both were declining but the death rate decreases more rapidly than birth rate due to improvement in medical facilities.
  • In 1961– 91 % growth rate became 2%.
  • In 1991– growth rate came down to 1.93%.
