Examine the decades 1970, 1990, and 2010 in this
population pyramid C for the United States. Consider any
significant shapes. In particular, note the large bulge that travels upward through the pyramid over time. This bulge
represents the baby boomer generation, a generation of Americans who were born in the United States immediately
following World War II (1939-1944). How do you think this generation has impacted the U.S. economy through the
years? How might it impact the U.S. economy and politics in the future?
