Study: 1 in 30 Babies Is a Twin

Posted by The Baby News

The number of twins born in America has greatly increased over the past few years, with 1 in ever 10 babies born being a twin.

Researchers attribute this spike to fertility treatments and women having babies in their 30s, where the chance of twins is more likely. It's unclear as to why the odds of twins increases in the 30s - one theory is that older women produce multiple eggs per cycle.

The statistic, derived from 2009 birth rates, found that twin births increased in all 50 states, but most drastically in lower New England, New Jersey and Hawaii.

Have you noticed an increase in the number of twins?
