Chances of having twins 'dramatically higher' from 20 years ago

One in 30 babies born in the United States is a twin, a new study says.

Seeing double? You're probably not alone.

Statistically speaking, it's actually more likely than ever that a mother will have twins or triplets, a new study says.

The Daily Mail cites a study done by the Centers for Disease Control and Michigan State University researchers that says that the chances for having twins has nearly doubled over the past two decades.

The study says that one of every 30 babies born in the United States will be born a twin, which is up from studies done in the 1980's. Those reports said that one of every 53 babies was a twin.

Rates of triplets being born have jumped even more, quadrupling since the studies done two decades ago, the Daily Mail reports.

Researchers cite the increased use of fertility treatments and an older generation of mothers having kids as possible reasons for the jump in multiple births.
