Abstract:This report presents a time-series analysis of changes in road safety in the U.S. from
the public-health point of view. A 50-year period is examined, from 1958 to 2008. The
emphasis is on the changes by decades in fatalities per population across different age groups.
The main findings are as follows. First, from 1958 to 2008, the overall fatality rate per
population decreased by 40%. Second, the decrease in the rate was age dependent (with the
largest decreases for the youngest and the oldest, and smallest decreases for the middle-aged).
Third, the overall fatality rate increased from 1958 to 1968, but it decreased for each of the four
following decades. Fourth, the changes in the rate for each decade were age dependent. Fifth,
the patterns of these age-dependent changes varied across the decades.
Examples of interventions that are likely to have age-dependent effects consistent with
the obtained differential age changes in the fatality rate are discussed. However, other
interventions are also likely to have relevant age-dependent effects on the fatality rate.
