AMERICA DEATH RATE RATE RISE IN PAST DECADES

WASHINGTON — The death rate in the United States rose last year for the first time in a decade, preliminary federal data show, a rare increase that was driven in part by more people dying from drug overdoses, suicide and Alzheimer’s disease. The death rate from heart disease, long in decline, edged up slightly.

Death rates — measured as the number of deaths per 100,000 people — have been declining for years, an effect of improvements in health, disease management and medical technology.
