Swimming pool drowning deaths in the US

It is a peculiar comfort to learn that as Americans have eaten more yogurt per capita, fewer of them have drowned in swimming pools, as though probiotics possessed some hitherto unrecognized buoyancy-enhancing property. The correlation is negative and remarkably strong across seventeen years, which is long enough to make a nutritionist wonder and a statistician sigh. One pictures a lifeguard handing out Chobani at the pool gate, confident in the protective power of cultured dairy.

Yogurt consumption in the US roughly doubled between 2005 and 2021, driven by the Greek yogurt boom that began around 2008 when brands like Chobani and Fage convinced Americans that breakfast could be both healthy and tolerable. Swimming pool drownings declined during the same period thanks to improved safety regulations, better pool barriers, and increased awareness of water safety—the Virginia Graeme Baker Pool and Spa Safety Act of 2007 being a landmark intervention. Both trends are products of a health-conscious, regulation-heavy era in American life: one pushing consumers toward fermented dairy, the other pushing homeowners toward pool fences. The shared variable is not yogurt but the general cultural drift toward risk mitigation and wellness optimization.

Seventeen years of yogurt and drowning data moving in opposite directions is a masterclass in how two entirely separate cultural shifts can produce a correlation that feels meaningful and is not. We eat more yogurt because marketing told us to, and we drown less because regulation told us to, and neither trend has the slightest opinion about the other. The cultures are unrelated.
