US lottery ticket sales

As Americans have spent more on lottery tickets, more cyclists have been killed on US roads, a correlation that suggests the same economy funding dreams of instant wealth is also funding the conditions that make cycling dangerous. The coefficient is 0.881 across eighteen years, during which both metrics climbed with the steady confidence of numbers that go up because the economy goes up, regardless of whether the outcomes are desirable. The lottery ticket and the bike ride: two bets on a better future with very different odds.

Lottery sales grew from about 52 billion to over 107 billion between 2005 and 2022, driven by larger jackpots, mobile purchasing, and state program expansion. Cycling fatalities grew from about 780 to over 1,000 as urban cycling increased without corresponding infrastructure investment. Both metrics track the same economic growth: more disposable income means more lottery spending and more urban commuting options, including cycling. The shared variable is simply prosperity—an expanding economy produces both recreational gambling and urban density, and both trends reflect a population with more money and more options than the infrastructure can safely support.

Eighteen years of lottery tickets and cycling deaths rising together is a reminder that economic growth creates both opportunity and risk in equal measure. The tickets sell because Americans are optimistic, and the cyclists die because American roads are not. Both trends are real, both are growing, and neither has the slightest awareness of the other's existence. The odds remain long. The lanes remain short.
