The Story
Hans Rosling was a Swedish doctor and professor. In 2005, he founded Gapminder with his son Ola and daughter-in-law Anna. In 2006 he gave a famous TED talk where colourful bubbles showed how countries had changed.
In 2010, on a BBC show, he showed 200 countries over 200 years in about four minutes. In around 1800, average life expectancy was about 30 years; by 2019 it was over 70. The book «Factfulness», published in 2018, teaches us to look at the world using data, not worries.
