2: The distribution of the ages of a nation's population has a strong influence on economic and social conditions. The following table shows the age distribution of U.S. residents in 1950 and the projected distribution in 2075, in millions of people.

Because the total population in 2075 is much larger than the 1950 population, comparing percent in each age group is clearer then comparing counts. Make a table of the percent of the total population in each age group for both 1950 and 2075. Use excel to enter the original data and to compute the percentages.

Using excel create two histograms with a vertical scale in percents for the 1950 and 2075 population data.
