The pie charts in Figure 3.38 give the percentages of Americans in three age categories in 1990 and 2050 (projected).

a. Consider the 1990 age distribution. The actual percentages for the three categories for 1990 were 87.5% (others), 11.3% (60–84), and 1.2% (85). Does the pie chart show these values accurately? Explain.

b. Consider the 2050 age distribution. The actual percentages for the three categories for 2050 were 80.0% (others),
15.4% (60–84), and 4.6% (85). Does the pie chart show these values accurately? Explain.

c. Using the actual percentages given in parts (a) and (b), draw flat (two-dimensional) pie charts to display these data. Explain why these pie charts give a more accurate picture than the three-dimensional pies.

d. Comment on the general trends shown in the two pie¦charts.
