Fewer women than men actively engage in planning for retirement, though women are more concerned than men about the retirement risks they face, according to a new report from LIMRA.

The survey reveals that only a third of women are actively involved in monitoring and managing their retirement savings, compared with nearly half of men (46 percent). Two-thirds of women are not confident that they will be able to live their chosen retirement lifestyle, yet only 26 percent of women spend time investigating financial products that could help them.

"We know from earlier studies that working women, on average, have accumulated 40 percent less than men for retirement, which was confirmed again in this study," said Cecilia Shiner, senior analyst, LIMRA retirement research. "Even though six in 10 women are concerned they aren't saving enough to last throughout their retirement, we see few women taking steps to mitigate for this risk."
