Baby Boomer is a U.S.citizen born between the years 1946 and 1960. These Boomers represent a relatively large segment of the population and outnumber any other group born during a similar period, such as those born from 1931 to 1945 or from 1961 to 1975. Over the years, they've tended to set the standard for consumption, production, and politics. They have had and will continue to have a big impact on the Social Security system. As labor, they've provided an amble pool of tax funds and thus sizable benefits to Social Security recipients during the 1980s and 1990s. When these Boomers retire in the 2020s and beyond, however, they will leave a big gap in the labor force and also demand a great deal from the Social Security system.
