Identification of Factors Contributing to the Decline of Traffic Fatalities in the United States from 2008 to 2012

Between 2005 and 2011, the number of traffic fatalities in the U.S. declined by 11,031, from 43,510 in 2005 to 32,479 in 2011. This decline amounted to a reduction in traffic-related deaths of 25.4 percent, by far the greatest decline over a comparable period in the last 30 years. This report describes a comprehensive analysis of the factors associated with fatality rates in states, especially as they relate to the substantial drop in fatalities occurring in the years from 2008 to 2011. The analysis included predictors representing a wide variety of potentially related factors including travel, demographics, the economy, vehicle safety systems, and state spending on several categories of infrastructure and safety improvements. A key insight into the analysis of factors producing the sharp drop in traffic fatalities was that the young contributed disproportionately to the drop-off in traffic fatalities. Of the reduction in traffic fatalities from 2007 to 2011, persons younger than 26 years of age accounted for almost 48% of the drop, though they were only about 28% of total traffic fatalities prior to the decline.
