Sad to hear that Hans Rosling has died from pancreatic cancer. For those that don't know him, he was a statistician and a founder of the Gapminder Foundation which aims to achieve sustainable global development using statistics to understand what is needed. Totally at odds to the current Putin/Trump/Brexit world of lies and fake news, he sought to use facts to improve policy decisions.
I really wish everyone would watch this video on population

Wouldn't fact based policy be better than twitter and fake news?
