Last October, the Chicago Cubs broke the last great sports curse when they defeated the Cleveland Indians in a thrilling seven-game series to win their first World Series since 1908. For long-suffering fans of the Cubs, it was a time to celebrate like never before. Fans flooded the streets, Bill Murray danced on SNL, and, unsurprisingly, a whole lot of couples got busy. Now, roughly nine months later, the city of Chicago is seeing the result of an entire city having celebratory sex on the same night, as Chicago Hospitals have reported an uptick in births that seems to be directly connected to the Cubs’ big win.
On the surface, it may seem ridiculous to believe that a city’s birthrate could be affected by a sporting event, but the post-championship baby bump is a pretty well-documented reality. For example, nine months after the Red Sox broke the legendary Curse of the Bambino in 2004, there was a noticeable jump in little members of the Red Sox nation.
And it’s not just Americans. In 2009, Andrés Iniesta scored a huge last minute goal against Chelsea FC, propelling FC Barcelona to the UEFA Champions League final. As a study details, the city of Catalonia saw a 16 percent increase in births nine months after Iniesta’s goal (it was initially reported that births increased by 45 percent, but that was later found to be a slightly exaggerated number).
Of course, baby booms can also be linked to non-sporting events,too. Some have claimed the birth of Prince George in 2013 created a “copy-Kate” effect in Britain and there is generally believed to be a “Christmas effect” which is why birth rates always spike around September.
So, as a new generation of Cubs fans enters the world, they can grow up knowing that if second baseman Ben Zobrist doesn’t hit an RBI double in the top of 10th inning, most of them probably don’t exist. And instead, we’d be talking about all the babies being born in Cleveland right now.
