Demographic Transition Model

1. Population density = population example: 270,000,000 people = 29 people/square km.
2. Birth or death rate = # of births (or) deaths per year example: 23,452 births = .025 = 2.5% birth rate.
3. Population Growth Rate (r) = births – deaths example: 20,000 births – 15,000 deaths = .01 = 1% pop.
