3. Look at the graph’s 1959 totals. What does the 4.30 level indicate? What does the level of 4.60 indicate?
What does the level of 1.66 indicate?
By how much did the U. S. population increase in that year?

4. Nearly 60,000 more people immigrated to the United States in 1965 than in 1964.
Why then does the top line in the graph dip down between those years?

5. What is significant about the number of births in 1972? (Hint: Look at the number of births for the first year of the baby boom.)
Why do you think 1964 is considered the final year of the baby boom?
