Which theory of population growth has three stages?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → The Theory of Demographic Transition
Option (2) The Theory of Demographic Transition — Correct. This theory links population growth to the level of economic development and says there are three basic stages of population growth: low growth in an underdeveloped society where both birth and death rates are high; a transitional stage of very high growth; and low growth again in a developed society where both rates have fallen.
NCERT (2025-26): “The Theory of Demographic Transition … Another significant theory in demography is the theory of demographic transition. This suggests that population growth is linked to overall levels of economic development and that every society follows a typical pattern of development-related population growth. There are three basic stages of population growth.…” “…The third (and last) stage is also one of low growth in a developed society where both death rate and birth rate have been reduced considerably and the difference between them is again small.…” “…Between these two stages is a transitional stage of movement from a backward to an advanced stage, and this stage is characterised by very high rates of growth of population.” |
