Fatal dog attacks in the US

As Americans have spent more money on lottery tickets, fatal dog attacks have increased, a correlation that suggests either that winning the lottery makes your dog aggressive or that both activities represent the same fundamental bet on unlikely outcomes. The coefficient is 0.888 across nineteen years, during which both metrics climbed with the steady optimism of trends powered by people who believe, against all evidence, that things will work out differently this time. The lottery ticket and the unfamiliar dog: two gambles with very different stakes.

Lottery sales grew from about 52 billion to over 107 billion between 2005 and 2023, boosted by larger jackpots, mobile purchasing, and state program expansion. Fatal dog attacks grew from about 28 per year to over 50, driven by larger breed popularity, the pandemic adoption boom, and inconsistent regulation. Both trends track consumer behavior in a growing economy: lottery spending rises with disposable income, and dog ownership rises with the same suburban affluence that enables both a backyard and a pet. The shared variable is simply American prosperity creating the conditions for both activities to expand.

Nineteen years of lottery tickets and dog attacks growing together is a correlation that captures two forms of American risk-taking: one financial, one physical, neither well-calibrated. The tickets sell, the dogs bite, and the shared variable is an economy that enables both without particularly caring about the outcomes of either.
