Everyday, an average of 150,000 people die worldwide. What kills them varies wildly from country to country.
Citing the collaborative research of hundreds of researchers from around the world, the following short video from Vox.com shows the number one cause of early death by country. The results clearly demonstrate the influence of geography, culture, and economics on human mortality.
Here is a map of the data pulled from the video.
The video also introduces the idea of measuring “years of life lost”, which compares the age of death to the potential maximum lifespan (presently an average of around 86 years). This method captures the true scope and tragedy of early death. After all, a country can have a high death rate because its aging population is reaching the limit of human longevity; hence why the leading causes of death in richer country are those that tend to strike the old, like stroke and heart disease. This shows that most people in those nations are managing to live long lives at or near (if not beyond) the potential human average.
But if most people in a given country are dying from things that occur well before old age, than it denotes serious socioeconomic and political problems: issues like war, lack of public health infrastructure, rampant poverty, and so on. Hence why poorer countries have more people dying from causes that are otherwise easily cured, treated, or even preempted in richer nations.
As the video points out, as many as 40 percent of the deaths in Sub-Saharan Africa occur to people less than five years old. This is a stunning figure, especially when one looks at the specifics: something as mundane in the developed world as diarrhea can be a death sentence in other parts of the world. And for all our concerns about violent crime, most people in the U.S., Europe, and other developed nations can rest assured that they are unlikely to die at the hands of another person (though for certain communities within these countries, that is a different story).
A country’s leading cause of death can also reveal certain peculiarities in their culture, history, or society. Persian Gulf countries have a strong subculture geared around drag racing and risky driving, leading to their unusually high rate of death by car accidents. This could be linked to high youth unemployment and a repressive social environment, which leads to boredom, angst, and the pursuit of these sorts of thrills. Meanwhile, China’s high rate of stroke deaths portends its rapid development and industrialization, but also spells trouble as it deals with rich-world problems without yet establishing a rich-world public health system.
This data is at once fascinating and disconcerting. It shows the huge level of disparity between certain parts of the world, and reaffirms how our success in life — including our capacity to live full, healthy lives — is largely a product of random chance. We are at the mercy of geography. Had I been born in Bolivia, the Congo, or Pakistan, I could have long died from the banal childhood afflictions I suffered without worry. Then again, if had I been born in North America, Europe, or Australia a century or two earlier, there would be a similar likelihood of dying from infectious disease.
