Using monthly seasonally adjusted data from 1960 to the present, calculate and graph the total workingage population (called the civilian noninstitutional population), the number of employed workers, the number of unemployed workers, and the number of workers in the labor force.

At the website of the Bureau of Labor Statistics, www.bls.gov/cps/cpsatabs.htm, find seasonally adjusted data since 1960 and graph the labor force participation rate for the overall working-age population aged 20 and older, and graph the labor force participation rates for males aged 20 and older and for females aged 20 and older. What are the major changes in these variables that have occurred since 1960?
