Austin Smith of Miami University analyzed data from the U.S. Fatality
Analysis Reporting System both before and after the 2007 daylight-saving
rule change, and found that the spring-forward transition increased
fatal crash risk by 5% to 6.5%, with four statistical tests suggesting
that the increase is explained by sleep deprivation. Smith concludes,
"Back-of-the-envelope calculations suggest that the spring transition
into DST caused over 30 deaths annually at a social cost of $275
million." I assume this estimate is for just the U.S.
