NCD mortality and morbidity
Of 56.4 million global deaths in 2015, 39.5 million, or 70%, were due to noncommunicable diseases (NCDs). The four main NCDs are cardiovascular diseases, cancers, diabetes and chronic lung diseases. The burden of these diseases is rising disproportionately among lower income countries and populations. In 2015, over three quarters of NCD deaths -- 30.7 million -- occurred in low- and middle-income countries with about 48% of deaths occurring before the age of 70 in these countries.
The leading causes of NCD deaths in 2015 were cardiovascular diseases (17.7 million deaths, or 45% of all NCD deaths), cancers (8.8 million, or 22% of all NCD deaths), and respiratory diseases, including asthma and chronic obstructive pulmonary disease (3.9 million). Diabetes caused another 1.6 million deaths.
