Max Roser, economist, geoscientist, philosopher, Founder and Program Director, Our World in Data: To see where we are coming from we must go far back in time. When you only consider what the world looked during our life time it is easy to make the mistake of thinking of the world as relatively static – the rich, healthy and educated parts of the world here and the poor, uneducated, sick regions there – and to falsely conclude that it always was like that and that it always will be like that. In 1950 two-thirds of the world were living in extreme poverty; in 1981 it was still 42%. In 2015 – the last year for which we currently have data – the share of the world population in extreme poverty has fallen below 10%. That is a huge achievement, for me as a researcher who focuses on growth and inequality maybe the biggest achievement of all in the last two centuries.
