Exercise 10

What is fertility rate ? Distinguish between replacement-level fertility rate and total fertility rate ( TFR ). Explain why reaching the replacement level fertility rate will not stop global population growth for about 50 years (assuming that death rates do not rise). Summarize the story of population growth in the United States, and explain why it is so high compared to other more-developed countries.
