The top 10 causes of death
Why do we need to know the reasons people die?
Measuring how many people die each year and why they died is one of the most important means – along with gauging how diseases and injuries are affecting people – for assessing the effectiveness of a country’s health system.
Cause-of-death statistics help health authorities determine the focus of their public health actions. A country in which deaths from heart disease and diabetes rise rapidly over a period of a few years, for example, has a strong interest in starting a vigorous programme to encourage lifestyles to help prevent these illnesses. Similarly, if a country recognizes that many children are dying of pneumonia, but only a small portion of the budget is dedicated to providing effective treatment, it can increase spending in this area.
High-income countries have systems in place for collecting information on causes of death. Many low- and middle-income countries do not have such systems, and the numbers of deaths from specific causes have to be estimated from incomplete data. Improvements in producing high quality cause-of-death data are crucial for improving health and reducing preventable deaths in these countries.
