Love this article from Our World in Data which describes how far we have come as a species and what challenges remain ahead. “Very few think the world is making progress. In this article, we look at the history of global living conditions and show that the world has made immense progress in important aspects.”
The data in this article uses a previous release of the World Bank’s poverty and inequality data in which incomes are expressed in 2011 international-$.
The World Bank has since updated its methods, and now measures incomes in 2017 international-$. As part of this change, the International Poverty Line used to measure extreme poverty has also been updated: from $1.90 (in 2011 prices) to $2.15 (in 2017 prices).
This has had little effect on our overall understanding of poverty and inequality around the world. But because of the change of units, many of the figures mentioned in this article will differ from the latest World Bank figures.
