Number of craft breweries in the US

As craft breweries have proliferated across America—opening at a rate that suggests the nation believes it does not yet have enough varieties of IPA—swimming pool drowning deaths have declined, producing a correlation that implies beer is somehow making pools safer. The coefficient is -0.909 across seventeen years, during which America got hoppier and less drowned, a combination that sounds like a public health victory nobody planned. One imagines a lifeguard cracking open a pale ale and feeling vindicated.

Craft breweries in the US grew from about 1,400 in 2005 to over 9,500 by 2021, driven by the same premiumization trend that lifted organic food, artisan coffee, and every other "craft" category. Pool drownings declined thanks to improved safety regulations, fencing requirements, and water safety education. Both trends are expressions of the same affluent, suburban, millennial-driven cultural shift: the same communities where craft breweries thrive are the same communities where pool safety standards are most rigorously enforced. The shared variable is disposable income and the infrastructure it buys: taprooms and pool fences, both funded by the same household budget.

Seventeen years of more breweries and fewer drownings is a portrait of a culture that is simultaneously drinking better beer and building better pool barriers, for reasons that have everything to do with affluence and nothing to do with hops. The brewery opens, the pool fence goes up, and the correlation between them is simply prosperity expressing itself in two different aisles. Cheers, safely.
