Factors Affecting Population Growth
Learning Objective
I can use graphs to explain how different factors affect population growth.
Key Concepts
Population pyramids divide data by gender, with females on one side and males on the other, and show population numbers for each five-year age interval.
Rwanda's population pyramid shows a fast-growing country, while Japan's shows a population that will begin to decline as fewer people reach reproductive age.
Countries in advanced stages of industrialization reach a point where both birth and death rates are low, and the population remains stable or even begins to decline.
