Americans live 75.3 years on average, fewer than Canadians (77.3) or the French (76.6) or the citizens of any Western European nation save Portugal. Health care influences life expectancy, of course. But a life can end because of a murder, a fall or a car accident. Such factors aren't academic — homicide rates in the U.S. are much higher than in other countries.
In The Business of Health, Robert Ohsfeldt and John Schneider factor out intentional and unintentional injuries from life-expectancy statistics and find that Americans who don't die in car crashes or homicides outlive people in any other Western country.
