Deaths from falling out of bed in the USUS plant-based milk total retail sales
As plant-based milk sales have grown, bed-fall deaths have risen, a correlation of 0.992 that adds oat milk to the already extensive list of things that correlate with falling out of bed in America. The almond milk pours, the body falls, and the chart makes no distinction between the two. At this point in the dataset, one begins to suspect that bed-fall deaths correlate with literally everything, and one would be correct.
Plant-based milk sales grew from about 1.2 billion to over 2.6 billion dollars between 2012 and 2021. Bed-fall deaths rose with the aging population. Both are smooth upward curves, and the correlation is the mathematical consequence of their identical direction. The oat milk drinkers (young, health-conscious) and the bed-fall victims (elderly, balance-impaired) are entirely different populations.
Ten years of plant-based milk and bed falls is another installment in the infinite series of things that correlate with elderly Americans falling out of bed. The milk is plant-based, the fall is gravity-based, and the correlation is math-based. The oat grows, the body falls, and the coefficient remains unmoved by the absurdity of the pairing.
