Question

Difficulty: MediumPopulation Concepts and Growth Dynamics

Match each stage of the Demographic Transition Model on the left with its corresponding birth and death rate characteristic on the right.

  • Stage 1 (High Stationary)High birth rate and high death rate, resulting in a low and fluctuating population size.
  • Stage 2 (Early Expanding)High birth rate accompanied by a rapidly falling death rate, leading to high natural population growth.
  • Stage 3 (Late Expanding)Falling birth rate and low death rate, leading to decelerating population growth.
  • Stage 4 (Low Stationary)Low birth rate and low death rate, resulting in a stable or very slow population growth.

Answer

Stage 1 (High Stationary) pairs with high birth and high death rates; Stage 2 (Early Expanding) pairs with high birth rate and rapidly falling death rate; Stage 3 (Late Expanding) pairs with falling birth rate and low death rate; Stage 4 (Low Stationary) pairs with low birth rate and low death rate.
Each stage of the Demographic Transition Model represents a specific evolutionary phase of birth and death rates as a society undergoes economic and social development. Stage 1 pairs high births with high deaths (low growth), Stage 2 pairs high births with plummeting deaths (rapid expansion), Stage 3 pairs dropping births with low deaths (slowing expansion), and Stage 4 pairs low births with low deaths (stationary equilibrium).

Step-by-Step Solution

1
Identify the demographic conditions of Stage 1.
High birth rates and high death rates cancel each other out, giving a low, fluctuating population.
Early agrarian societies faced high infant mortality and disease.
2
Identify the demographic conditions of Stage 2.
Birth rates stay high while death rates plunge, yielding maximum natural increase.
Improvements in healthcare, diet, and sanitation dramatically lower mortality before fertility norms change.
3
Identify the demographic conditions of Stage 3.
Birth rates fall noticeably while death rates remain low.
Socio-economic development, female education, and urban lifestyle reduce family size preference.
4
Identify the demographic conditions of Stage 4.
Both birth and death rates level off at low values.
Industrialized societies achieve demographic equilibrium with low growth rates.
