Q: What are the main differences between rich and poor countries with respect to causes of death?

In high-income countries more than two thirds of all people live beyond the age of 70 and predominantly die of chronic diseases: cardiovascular disease, chronic obstructive lung disease, cancers, diabetes or dementia. Lung infection remains the only leading infectious cause of death.

In middle-income countries, nearly half of all people live to the age of 70 and chronic diseases are the major killers, just as they are in high-income countries. Unlike in high-income countries, however, tuberculosis, HIV/AIDS and road traffic accidents also are leading causes of death.

In low-income countries less than one in five of all people reach the age of 70, and more than a third of all deaths are among children under 15. People predominantly die of infectious diseases: lung infections, diarrhoeal diseases, HIV/AIDS, tuberculosis, and malaria. Complications of pregnancy and childbirth together continue to be leading causes of death, claiming the lives of both infants and mothers.

Q: How many young children die each year?

More than 8 million deaths in 2008 were among children under five years of age, and 99% of them were in low- and middle-income countries.
