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 1.5 million (2.7%) deaths in 2012, up from 1.0 million (2.0%) deaths in 2000. Lung cancers (along with trachea and bronchus cancers) went up to become the 5th leading cause of death in 2012, killing 1.1 million men and 0.5 million women in 2012. Injuries continue to kill 5 million people each year. Road traffic injuries claimed about 3400 lives each day in 2012, about three-quarters of whom were men and boys.
