Why middle age can be deadly for less-educated white Americans

The death rate for white, middle-aged, less-educated Americans is climbing, while the overall average mortality rate in the nation continues to fall, according to recent research. The findings have prompted speculation over the trend, which is driven by rising substance abuse and suicide rates.
Countries in Europe such as the U.K., France, and Germany show no similar trend. In those nations, the death rate for white, middle-aged, less-educated populations continues to fall, similar to other groups, as technological advances and health-care improvements increase longevity.
