The number of people killed in motor vehicle crashes has fallen over the last decade. The death toll increased 7 percent in 2015, though it still is much lower than it was in 2005, when it began a sharp decline, or in 1975, when the U.S. Department of Transportation began keeping track.

Fatality rates per population and per mile traveled have dropped even more rapidly. The crash death rate per population has fallen by nearly half since 1975, but increased 6 percent from 2014 to 2015.

More men than women die in motor vehicle crashes. Men typically drive more miles than women and are more likely to engage in risky practices.
