# The distribution of the ages of a nation’s population has a strong

Question 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.
• Insert the histograms into a word document and discuss      the main features of each histogram and compare and contrast them.
