Match each stage of the Demographic Transition Model in Group I with its corresponding birth/death rate behavior and structural population pyramid profile in Group II.
- Stage 1 (High Stationary)High Crude Birth Rate matched by a high, fluctuating Crude Death Rate, yielding near-zero natural growth and a steeply concave population pyramid.
- Stage 2 (Early Expanding)High Crude Birth Rate accompanied by a rapidly falling Crude Death Rate, yielding a high Rate of Natural Increase and an expansive, broad-based population pyramid.
- Stage 3 (Late Expanding)Significantly declining Crude Birth Rate coupled with a low, stable Crude Death Rate, leading to slowing natural growth and a narrowing pyramid base.
- Stage 4 (Low Stationary)Low Crude Birth Rate balanced by a low Crude Death Rate, producing a negligible Rate of Natural Increase and a column-shaped or beehive population pyramid.
Answer
Stage 1 (High Stationary) matches high birth rate and high fluctuating death rate with near-zero growth; Stage 2 (Early Expanding) matches high birth rate and rapidly falling death rate with high natural increase; Stage 3 (Late Expanding) matches declining birth rate with low death rate causing a narrowing pyramid base; Stage 4 (Low Stationary) matches low birth and death rates producing a beehive or column-shaped pyramid.
Each Demographic Transition Model stage uniquely links demographic vital rates to population pyramid structure: Stage 1 pairs high fluctuating birth/death rates with a concave pyramid; Stage 2 pairs high birth rates and falling death rates with a broad-based expansive pyramid; Stage 3 pairs falling birth rates with a narrowing base; and Stage 4 pairs low birth/death rates with a column or beehive shape.
