Avocado consumption per capita

It appears that somewhere in the great cosmic ledger, the universe has decided that Americans cannot simultaneously enjoy both creamy fruit and the simple pleasure of not drowning, and has enforced this rule with the kind of mathematical precision normally reserved for planetary orbits. As avocado consumption climbed steadily from 2005 to 2021—reaching heights that would have seemed obscene to anyone eating guacamole in the early 2000s—pool drowning deaths declined as if someone had quietly installed invisible safety nets across the nation's suburban backyards. One went up, the other went down, and somewhere a data analyst who simply wanted to know if there was any relationship between vegetables and water safety is now questioning their entire career.

The genuine culprit here is almost certainly economic confidence and demographic shift. Americans with disposable income buy both expensive avocados and install swimming pools, but they also tend to be the same people who can afford swimming lessons, pool supervision, and proximity to emergency services—factors that actually correlate with pool safety outcomes. Between 2005 and 2021, real household incomes for higher-income brackets increased substantially while pool ownership concentrated among wealthier demographics, and simultaneously, awareness campaigns and stricter regulations around water safety gained serious traction. To put it another way: the same economic forces that put a four-dollar avocado on your toast also put a lifeguard on duty and a fence around your backyard.

What we're witnessing is the human brain's magnificent ability to perceive a relationship between two entirely unrelated phenomena moving in opposite directions, which is to say we're good at noticing patterns even when the pattern is just coincidence wearing a very convincing hat. The avocado-drowning correlation tells us nothing about either avocados or drowning, and everything about how easy it is for statistics to whisper stories that never actually happened. We saw them move together and believed in their kinship.
