Standard life expectancy at birth dropped to 78.8 years from 78.9 just a year earlier. Preliminary analysis suggests the increase in deaths may have been driven by drug overdoses and an unusually severe flu season in early 2015, which may have exacerbated potentially fatal conditions such as heart disease.
The number of people who died in car crashes was 37,757, which was also an increase of 12 percent.
Gun deaths, including homicides and suicides, totaled 36,252 which was also up 7 percent.
Suicide in the United States has surged to the highest levels in nearly 30 years, a federal data analysis has found, with increases in every age group except older adults. The rise was particularly steep for women. It was also substantial among middle-aged Americans, sending a signal of deep anguish from a group whose suicide rates had been stable or falling since the 1950s.
The suicide rate for middle-aged women, ages 45 to 64, jumped by 63 percent over the period of the study, while it rose by 43 percent for men in that age range, the sharpest increase for males of any age. The overall suicide rate rose by 24 percent from 1999 to 2014, according to the National Center for Health Statistics, which released the study on Friday.
The increases were so widespread that they lifted the nation’s suicide rate to 13 per 100,000 people, the highest since 1986. The rate rose by 2 percent a year starting in 2006, double the annual rise in the earlier period of the study. In all, 42,773 people died from suicide in 2014, compared with 29,199 in 1999.
