How Global Health and Wealth Has Changed Over 221 Years
At the dawn of the 19th century, global life expectancy was only 28.5 years.
Outbreaks, war, and famine would still kill millions of people at regular intervals. These issues are still stubbornly present in 21st century society, but broadly speaking, the situation around the world has vastly improved. Today, most of humanity lives in countries where the life expectancy is above the typical retirement age of 65.
At the same time, while inequality remains a hot button topic within countries, income disparity between countries is slowing beginning to narrow.
This animated visualization, created by James Eagle, tracks the evolution of health and wealth factors in countries around the world. For further exploration, Gapminder also has a fantastic interactive chart that showcases the same dataset.
The Journey to the Upper-Right Quadrant
In general terms, history has seen health practices improve and countries become increasingly wealthy–trends that are reflected in this visualization. In fact, most countries drift towards the upper-right quadrant over the 221 years covered in the dataset.
However, that path to the top-right, which indicates high levels of both life expectancy and GDP per capita, is rarely a linear journey. Here are some of the noteworthy events and milestones to watch out for while viewing the animation.
1880s: Breaking the 50-Year Barrier
In the late 19th century, Nordic countries such as Sweden and Norway already found themselves past the 50-year life expectancy mark. This was a significant milestone considering (Read more...)
