Question

How have population changes raised issues for Americans as they entered the 21st century?

Answer 1

The specter of an aging population has spawned numerous government commissions and scores of legislative proposals to restructure Social Security and Medicare. Long-term projections abound: by one estimate, providing even the same level of benefits for a growing older population could double the share of the gross domestic product (GDP) now supporting those programs.

Hope this can help.
