It's no secret that many Americans aren't saving enough for retirement, but a big chunk of households have saved nothing at all.
Nearly a third, or 31% of U.S. adults said they had no savings or pension to help them afford retirement, according to the Federal Reserve Board.
Even more alarming: 19% of those very close to retirement age, between the ages of 55 and 64, said they had no savings.
As a result, more than half of these respondents said they planned to either work full-time or part-time during their retirement years.
Meanwhile, a quarter of those surveyed said they didn't know how they would afford their golden years.
A big part of the problem: many low- and middle-income households "have little financial cushion at all" and often lack even basic emergency savings, the Fed survey found.
Plus, around half of workers and the majority of part-time workers don't receive retirement benefits at work, making it even harder to save.
