"Between 1999 and 2009, reliance on Social Security for at least 80 percent of retirement income ballooned by 48 percent among men aged 65 an older, according to a report released today.
Among women, such reliance on Social Security grew 26 percent, the Institute for Women's Policy Research said.
Social Security, the largest source of retirement income, was the main income source in 2009 for 5.7 million men (or more than one-third of men aged 65 an older)."
