Theories and Eras of Growth

The four eras of India’s population growth in order, and what the three population theories say and who gave them.

Trick 1

Four eras of population growth

➜ oldest to newest — each era 30 years

Steve’s goat eats slowly.

  1. 1Stable population1891-1921 · only 1.26 crore added in 30 years · the 1918 epidemic took 1.4 crore lives
  2. 2Era of growth1921-1951 · 1921 = “Year of the Great Divide”
  3. 3Population explosion1951-1981 · growth rate crossed 20% for the first time (21.6% in 1951-61)
  4. 4Signs of slowing1981 to now · 17.64% in 2001-2011 — the lowest in the past century

The era boundaries fall 30 years apart: 1891 → 1921 → 1951 → 1981. Population did not fall in 2001-2011 — only the growth rate slowed (18.14 crore more people in 2011 than in 2001).

Only as many people as give each person the highest income
