Middle-aged women are less likely to be happy than the rest of the American population, a new survey finds.

Worries about aging parents and other family members nag many women aged 35 to 54, according to a poll by Pursuant Inc. Money and time are also big concerns. The poll surveyed more than 1,100 women who have at least one living parent.

About 20% said they were very happy. That compares with 34% of the U.S. population overall, according to another survey by the Pew Research Center this year.
