Per capita cheese consumption in the US

It turns out that Americans have spent the last two decades locked in a peculiar dance with dairy products and traffic, the two moving together as though choreographed by someone who had never actually seen either cheese or a pedestrian. One might have thought these two phenomena would be entirely independent—the consumption of aged cheddar having nothing whatever to do with whether someone makes it safely across a street in Toledo—and yet here we are, with a correlation so robust it makes you wonder if the universe is simply messing with us. The pattern exists. That is the whole problem.

The likeliest culprit, rather boringly, is that both trends have been riding the coattails of American population growth and increasing urbanization over these twenty years—more people means more cheese consumed in aggregate and, tragically, more pedestrian deaths in the absolute sense. Add in the economic boom-and-bust cycles of the 2000s and 2010s, which would have expanded both restaurant dining and suburban sprawl simultaneously, and you've got your confounding variable doing most of the heavy lifting. A 2002 pedestrian could expect a per-capita cheese intake of roughly 33 pounds annually; by 2022, that figure had climbed to nearly 39 pounds—an increase that happened to coincide, almost precisely, with a doubling of fatalities from roughly 4,600 to 6,500 per year.

What this correlation really demonstrates is how readily two entirely unrelated trends will march together when driven by the same broad historical forces—population, prosperity, the endless American appetite for both convenience and space. We see cheese and death holding hands across a chart and congratulate ourselves on noticing the pattern, when really we're just watching two consequences of the same fundamental momentum. The universe, it seems, is not messing with us at all. We're just very good at pattern-making.
