However, there is some limited evidence that sports victories can cause spikes in birth rates in the city or region whose team won the game. Multiple surveys conducted in Spain have suggested that birth rates in Catalonia shoot up nine months after local teams win big games, and there were anecdotal reports that Boston experienced a baby boom nine months after the Red Sox finally won the World Series in 2004. After New Zealand defeated France in the World Cup, multiple hospitals reported an increase in their birth rates nine months after the fact.
These reports are difficult to corroborate, though, simply because there are so many other confounding factors that could also cause an increase in births in a particular region. But it's still a cute commercial, and who knows? Maybe this will compel some researchers to finally roll up their sleeves and get to the bottom of whether Super Bowl babies are indeed a phenomenon.Among the confounding factors is the fact that there has been an historical tendency for a rise in births in early autumn, following what appears to be a national pattern of baby-making in the winter months. You can look at the data at the CDC website. So, we would have to see if, in fact, Super Bowl winning cities had a statistically significantly higher number of births than other cities during that time of year. A complication, of course, is that most city or county level data are not collected nationally, so you would have to go state-by-state to work this out. Did anyone really do this prior to the Super Bowl? I doubt it. What I don't doubt, however, is the ability of the NFL to insert itself into the national consciousness in ways that divert our attention from the long-term injuries occurring to those players on the field...(full disclosure--the only injury I have ever experienced occurred playing high school football).
