The "forgotten generation," about 64 million Americans born between 1965 to 1980 and known as Generation X, are unprepared financially for retirement, according to a new study, warning about their "dismal retirement outlook."

The National Institute on Retirement Security wrote in a report that Generation X was the first generation to enter the labor market following the shift from defined benefit pension plans to 401(k)-style defined contribution accounts.

Author of the report and NIRS research director, Tyler Bond, wrote in a statement, "When looking at median retirement savings levels for Generation X, report finds that the bottom half of earners have only a few thousand dollars saved for retirement, and the typical household has only $40,000 in retirement savings." Shockingly, the study found approximately 40% of the generation have saved not even a single cent towards retirement.
