How Income Relates to Life Expectancy

It is no surprise that wealthier countries, like wealthier people, tend to live longer. But how strong is this correlation? In a video released by The Gapminder Foundation, Swedish academic and professor Hans Rosling uses detailed but digestible visual data to explore the link between a nation’s wealth –namely its gross domestic product, or GDP — and the average longevity of its people.

Ultimately, the findings do indeed confirm that rich societies live longer. But what the data also show is that those countries in the middle range of GDP — e.g. the developing world — display a broad range in life expectancy, from low to surprisingly high. This illustrates the discrepancy in how states invest their growing wealth, and whether the fruits of their development are going to their people.
