Organic food salesDeaths from falling out of bed in the US
As organic food sales have grown in the United States, deaths from falling out of bed have increased with a correlation of 0.996, which is the kind of number that makes you wonder if organic produce is making Americans' sleep more violent or if Whole Foods has somehow become a risk factor for geriatric safety. It is neither, obviously, but the chart is 0.004 away from perfect and does not care about your objections.
Organic food sales grew from about 14 billion dollars in 2005 to over 63 billion by 2021, on a smooth growth curve driven by health consciousness and mainstream availability. Bed-fall deaths rose as the population aged. Both are perfectly monotonic upward curves across seventeen years, and the correlation is a mathematical consequence of their identical shape. The organic food consumer and the bed-fall victim are related only in the broadest demographic sense: the same aging population that is eating healthier is also falling out of bed more, because age increases both health consciousness and fall risk.
A correlation of 0.996 between organic food and bed falls is the biography of an aging, health-conscious nation expressed in two metrics that share nothing except an upward trajectory. The kale is organic, the bed is hazardous, and the correlation between them is the purest form of demographic coincidence. America eats better and falls harder, for entirely separate reasons, at the same rate. The produce is certified. The mattress is not.
