A segment of baby boomers is now taking on extended caregiving responsibilities, according to a study put out by retirement organization AARP.
Many of the so-called "sandwich generation," made up of individuals between ages 45 and 55, minister care to their children and their parents.
Low-income individuals "feel more stressed about their responsibilities and are less able to to take time off from work to care for others," says Bill Novelli, AARP's executive director.
Asian-Americans, Hispanic-Americans, and African-Americans, especially those with low incomes, "feel heavily burdened," he adds.
The survey found that people born outside of the United States are more likely to provide care for others (43 percent) than those born in the US (20 percent).
Despite their own responsibilities, nearly 7 in 10 of those surveyed do not expect their children to take care of them in old age.
