The top 10 causes of death
The 10 leading causes of death in the world, 2000 and 2012
Q: What are the main differences between rich and poor countries with respect to causes of death?
In high-income countries, 7 in every 10 deaths are among people aged 70 years and older. People predominantly die of chronic diseases: cardiovascular diseases, cancers, dementia, chronic obstructive lung disease or diabetes. Lower respiratory infections remain the only leading infectious cause of death. Only 1 in every 100 deaths is among children under 15 years.
In low-income countries, nearly 4 in every 10 deaths are among children under 15 years, and only 2 in every 10 deaths are among people aged 70 years and older. People predominantly die of infectious diseases: lower respiratory infections, HIV/AIDS, diarrhoeal diseases, malaria and tuberculosis collectively account for almost one third of all deaths in these countries. Complications of childbirth due to prematurity, and birth asphyxia and birth trauma are among the leading causes of death, claiming the lives of many newborns and infants.
Q: How has the situation changed in the past decade?
Ischaemic heart disease, stroke, lower respiratory infections and chronic obstructive lung disease have remained the top major killers during the past decade.
Noncommunicable diseases (NCDs) were responsible for 68% (38 million) of all deaths globally in 2012, up from 60% (31 million) in 2000. Cardiovascular diseases alone killed 2.6 million more people in 2012 than in the year 2000.
HIV deaths decreased slightly from 1.7 million (3.2%) deaths in 2000 to 1.5 million (2.7%) deaths in 2012. Diarrhoea is no longer among the 5 leading causes of death, but is still among the top 10, killing 1.5 million people in 2012.
Tuberculosis, while no longer among the 10 leading causes of death in 2012, was still among the 15 leading causes, killing over 900 000 people in 2012.
Maternal deaths have dropped from 427 000 in the year 2000 to 289 000 in 2013, but are still unacceptably high: nearly 800 women die due to complications of pregnancy and childbirth every day.
Injuries continue to kill 5 million people each year. Road traffic injuries claimed nearly 3500 lives each day in 2012 – more than 600 more than in the year 2000 – making it among the 10 leading causes in 2012.
