Trends: Celebrities Pregnant with Twins

Single births are so 2016. This year, it’s all about the multiples. (Births, duh.)

Seriously, this year has started off with a bang regarding celebrity birth announcements. First up, superstar/icon/QUEEN Beyonce announced that she’s pregnant with twins in an Instagram post that dropped February 1st. Naturally, the world went crazy (and that Instagram post is now the most-liked post ever). Beyonce also released photos from her pregnancy photoshoot, and later performed at the Grammys in a tribute to motherhood. As you do.

Not even two weeks later, it was confirmed that Amal Clooney (you know, George’s wife) is expecting twins. And the twins will be a boy and a girl.

There’s another couple that might be expecting twins. It’s confirmed that “The Walking Dead” actor Steven Yeun and his wife Joana Pak are expecting a child. One of Yeun’s recent Instagram posts was a series of photos of he and his pregnant wife, of which one photo features him holding up two fingers. The photo’s caption is two bee emoji.

So either they’ll also be welcoming twins this year, or Yeun is part of the Beyhive. I don’t know. We’ll find out.

It’s crazy that all these celebrities are having twins right now. No idea if any of them are through IVF and don’t want to speculate, but it’s interesting how all the pregnancies are syncing up.

China’s Sex Ratio: How Skewed Is It?

Late last year, China ended its one-child policy, where each family was only allowed to have…one child. (Bet you didn’t see that one coming.) Though its rules have relaxed in recent years, this is the first time the practice has been officially abolished. (But we’ll see how long it takes for the policy to actually die down, data-wise.)

We’ve all heard about how skewed China’s sex ratios are; we’ve heard about how the country overwhelmingly favors male children to the detriment of an equal sex ratio. But what are the numbers behind this phenomenon?

Consulting firm Nomura Research Institute, Ltd. released data in 2010 that revealed that Chinese women bear .71 of female births during their lifetime. That year, men outnumbered women by 50M+. The birth rate at that time was 120 boys per 100 girls, which works out to a sex ratio of 1.2.

If you’re a visual learner, here’s what that ratio looks like, especially in context with other countries:

As Business Insider notes:

That means lots of single, possibly angry males. Hard to imagine anything good coming out of this.

The policy was made into law in 1979, and abolished in 2015. That’s 36 years. Thirty-sex years of selected sex-selection in favor of boys at the expense of girls. (Fun fact: Kim Kardashian West participated in this when she was trying to get pregnant with her now-son.)

Scary, right? We’ll see how the new policy helps attempt to reverse this long-running trend.

Lucy and Maria Aylmer: How Many Twins Look Racially Different?

This week, the Internet has been fascinated by a set of English fraternal twins Lucy and Maria Aylmer. But there’s something special about them: Lucy has pale skin and red hair, while Maria has brown skin and brown curly hair.

In other words, one twin looks white, and the other twin looks black.

Their parents have a mixed racial background: their mother is half Jamaican, and their father is white.

Occasionally, stories like theirs pop up every now and again. In 2009, another British mixed-race couple produced not one, but two, sets of identical twins who each looked very racially different from their sibling.

But how common is this?

Unfortunately, there are no statistics that track this. From “The Associated Press:”

The phenomenon is so uncommon that there are no statistics to illustrate its probability, although it is thought likely to become more common because of the growing number of mixed-race couples.

To give you an idea on exactly how uncommon this is (using numbers!), Dr. Sarah Jarvis of Britain’s Royal College of General Pracitioners, said in 2009 (though it still applies today):

“Even non-identical twins aren’t that common. Non-identical twins from mixed parents, of different races, less common still. To have two eggs fertilized and come out different colors, less common still. So, to have it happen twice must be one in millions.”

But that’s just a guess, though the BBC reported chances closer to 1 in 500 in 2011. We won’t know until we actually start tracking the numbers.

How Many People Fantasize About Having Sex With Identical Twins?

I read an NPR article on twins recently, calling millennials “Generation Twin.” This name applied due to the fact that one million more twins were born between 1980 and 2012. (This checks out with my personal anecdotal evidence: I graduated high school in 2004, and my class of 106 students boasted three sets of twins.)

“The Atlantic” goes a bit deeper into why this is: The rise in twins is due to the rise in fertility drugs, most notably IVF. Older women are the ones mostly using fertility drugs, and producing most of the babies. Also, older women are statistically more likely to have twins than younger women.

Here’s a handy table to visualize the rise in twins over the past decades:

That got me wondering if sexual fantasies about twins (both identical and fraternal) have also increased.

After doing some digging, I really couldn’t find anything. I didn’t find any studies about sexual fantasies, or fantasies coming true, involving twins.

The closest I got was the recent study on sexual fantasies by researchers at Canada’s University of Quebec at Trois-Rivieres, published in the “Journal of Sexual Medicine.” “Business Insider” helpfully took all the data for male fantasies and put it together. The closest question the researchers asked the 717 men used about twins was about having sex with two women. Over 84% of men reported this fantasy, but we cannot extrapolate that this necessarily means twins.

The identical-twin fantasy didn’t show up for the women either, but that’s perhaps more understandable: Women aren’t generally depicted as having that particular fantasy (though I’m sure there are some outliers).

I find it strange that a fantasy that looms so large in popular culture (for men, at least) has basically no data to back it up.
