Single women need to be saving even more since they live longer and are more likely to outlive their savings.

Retirement savings in the US are low across the board - but they're even lower for single people.

"Single people tend to be less prepared for retirement than their married counterparts," writes the Economic Policy Institute (EPI) in a new report, "The State of American Retirement." "Even among those approaching retirement (age 56 - 61), most single men and women do not have any retirement account savings."

Only 43% of single men and 42% of single women have retirement account savings at all (scroll over the chart below to see how the numbers have changed over the years):

And those who do have savings accounts aren't setting aside nearly enough. Among single men with retirement accounts, the accounts hold an average of $34,000. Among single woman, there's an average of $30,000 saved:

In general, the EPI notes, people need to set aside more, but women are particularly vulnerable because they live longer and are more likely to outlive their savings.
