More U.S. women are having twins these days.
Health officials say one in every 30 babies is a twin. That's a
huge increase over the last 30 years. In 1980, only one in 53
newborns was a twin.
Experts attribute the jump mainly to medical treatments and
procedures that help infertile couples. But they note that there
are more older moms today. For some reason, women in their late 30s
have twins at a higher rate.
The Centers for Disease Control and Prevention released the
twins report on Wednesday.
