Retirement savings numbers are falling across age groups, says a November Harris Interactive poll.

The November survey, which included 2,151 adults from around the U.S. found 34% of Americans have no retirement savings and 27% have no personal savings.

For baby boomers, many of whom are quickly nearing retirement age, 25% of those surveyed have no savings for retirement. Of those who are 65 and older, the proportion was 22%.

In terms of portfolio mix, 70% of adults said they have not changed their portfolio mix in the last six months. Eighteen percent report keeping their retirement investments mostly in stocks and mutual funds and 22% say they keep retirement funds in an equal mix of stocks/mutual funds and investments such as bonds and money market funds.

“Current economic conditions seem to be driving somewhat less risky investment behavior by Gen Xers, which goes against the grain of traditional investment advice,” said Harris Vice President of Financial Services Research, Barbara Bertner, of the findings. Those who are closer to retirement age, however, and do not have any savings, may need to seek alternative sources of income or delay retirement.
