Mortality and global health estimates

Causes of death: Ischaemic heart disease, stroke, chronic obstructive lung disease and lower respiratory infections have remained the top killers during the past decade. Chronic diseases cause increasing numbers of deaths worldwide. Diabetes caused 1.6 million (2.8%) deaths in 2015, up from 1.0 million (1.8%) deaths in 2000. Deaths due to dementias more than doubled between 2000 and 2015, making it the 7th leading cause of global deaths in 2015. Injuries continue to kill 5 million people each year. Road traffic injuries claimed about 3700 lives each day in 2015, about three-quarters of whom were men and boys.
