Bicyclist traffic fatalities

As Americans have purchased more nutrition and energy bars, more cyclists have been killed on US roads, a correlation that connects the fueling of athletic activity to the fatality of athletic activity with the dark efficiency of a chart that does not care about your training plan. The coefficient is 0.878 across eighteen years, during which both curves rose with the determination of trends powered by the same health-conscious, active demographic. The bar provides energy. The road takes it away.

Nutrition bar sales grew from about 2.5 billion to over 7 billion dollars between 2005 and 2022, driven by the snacking revolution, protein-obsessed fitness culture, and the convenience economy. Cycling fatalities grew from about 780 to over 1,000 during the same period. Both metrics serve the same health-oriented, active consumer: the person buying a Clif Bar at the gas station and the person cycling to work are often the same person, or at least attend the same gym. The shared variable is the active lifestyle demographic—a growing population that exercises more, eats performance food, and commutes by bicycle in cities that have not built the infrastructure to keep them safe.

Eighteen years of energy bars and cycling deaths growing together is a portrait of a demographic that is better served by the food industry than by the transportation department. The bars fuel the ride, the roads fail the rider, and the correlation between them is simply the same health-conscious consumer viewed from the grocery aisle and the emergency room. The macros are optimized. The lane markings are not.
