Thirty is fast becoming the new 20 for American moms. In fact, more U.S. women than ever before are having children in their 30s, according to a report by Business Insider. And somewhat counter-intuitively they are, overall, healthier later in life than those who had babies in their 20s; and they may live longer and earn a higher income. They also are more likely to have twins.
The tables turned in 2016, Business Insider says, when more American women had babies in their early 30s than in their 20s. Whether because of career or other life goals, women are now 25% older when they give birth compared to 50 years ago.
But the news outlet reports, they are taking chances with their fertility: Between the ages of 20 and 24, women have an 86% chance of conceiving after trying for a year. But that chance falls to around 50% when women reach their late 30s.
What’s more, women in their 20s have a much higher chance of getting pregnant without miscarrying—and a lower risk of conditions such as gestational diabetes, preeclampsia, and high blood pressure.
But when it comes to health later in life, waiting until your 30s to give birth is better. Research shows that moms who first gave birth in their early 30s report higher energy, better fitness, and fewer aches and pains compared to moms who first gave birth in their early 20s.
And that might help explain another scientific finding. Women who have kids in their 30s might also live longer. According to a paper published in 2015, women who had their last child after age 33 were twice as likely to live past 95, compared to women who had their last child before their 30th birthday.
But what about the kids? If their moms gave birth in their 30s instead of their 20s, those kids might be safer, smarter, or even taller.
On top of that, there might be more of them. That’s right, because if you wait until your 30s, you’re more likely to have twins. Older women have higher levels of a hormone called FSH, which stimulates the ovaries. Normally, women release just enough FSH to ovulate or release one egg, but near menopause, they produce a ton of it, which can cause two eggs to ovulate and ultimately result in twins.
So if you want to have a large, healthy family, the good news is, the cutoff date is getting later all the time.
