Although this graph only shows life expectancy by country, according to Max Roser of OurWorldInData.org: “Since 1900 the global average life expectancy has more than doubled and is now approaching 70 years. No country in the world has a lower life expectancy than the [the] countries with the highest life expectancy in 1800.”
What else is there to say?? I was truly surprised by this fact. Although I knew that life expectancy increased, I didn’t expect it to be this much!
Unfortunately there are still substantial differences between regions, with sub-saharan Africa having the lowest life expectancy at around 50 years. However, one should also mention that even the countries in this region experienced increases of 10 or more years during the last century and that, I think, is a reason for hope.
