18. Population Pyramid Questions
Compare your country to your graphs in note – Label your pyramid as Rapid, Slow or Zero Growth
What is the fertility rate for your country? (use website)
What is your country’s annual growth rate? (use website)
What is your countries double time? (70/annual growth rate)
Compare your population pyramid to your countries 1990 population pyramid. How has the population growth for the following population groups changed. What impact will this change have on your country
Use the following definitions of population groups to analyze your graphs:
65– “older”
15– “middle”
0– “younger”
