What are the stages of the demographic transition model?
Stage 1: This is a state of high birth and death rates culminating in low population growth overall. Stage 2: With a consistently high birth rate and decreasing death rate, population growth surges. Stage 3: As the birth rate falls and the death rate remains low, the population continues to increase.
