Demographic Transition Model
Diagram Courtesy of Max Roser
Stage 1 ➪ High CBR, High CDR, low growth rate
Stage 2 ➪ High CBR, lowering CDR, high growth rate
Stage 3 ➪ lowering CBR, lowering CDR, lowering growth rate
Stage 4 ➪ low CBR, low CDR, low/negative growth rate
Pre-industrial Stage | Transitional Stage | Industrial Stage | Post-industrial Stage |
Birth rate is high to compensate for high infant mortality rate. Poorer countries are in this stage. | Industrialization begins. Access to food and improved healthcare lowers death rate. | Death rate drops due to improved medicine, and modernization. Mostly developed countries are in this stage. | Birth rate drops to equal zero population growth. If Birth rate falls below death rate than population will decrease |
