Pie Chart: 3: Causes of Disease
The two pie charts show differences in the causes of diseases in rich countries and in the developing world. The biggest difference is that infectious diseases still kill millions of people in poorer countries, whereas in the wealthy nations, they account for only 1% of deaths.
In both rich and poor countries heart disease is the biggest single killer. It accounts for almost a quarter of deaths in the affluent countries, at 24%, but almost double that in the poorer countries, at 43%. Cancer is also a major cause of death. In the industrial countries, 21% of deaths are due to cancer. However, in third world countries, it only makes up 9% of fatalities. The greatest difference however, is infectious diseases. These make up almost half of all deaths in poorer countries, but only 1% of diseases in developed countries. In contrast, over half of deaths in the developed world are the result of other diseases. This compares to just 2% of deaths in poorer countries.
In summary, most people in poorer countries die because of simpler, more treatable infectious and parasitic diseases. They also suffer because of lack of resources to treat heart disease, whereas people in richer countries die due to cancer heart disease, and a wider range of other illnesses.
