https://blogs.worldbank.org/en/opendata/shared-prosperity-constitutes-both-income-growth-and-inequality- The vision of the World Bank is to end extreme poverty and boost shared prosperity on a livable planet. The number of people who live in extreme poverty — i.e., less than $3 a day — is an important indicator to track the first part of this vision. To capture shared prosperity, the second part, requires a measure that includes not just the extreme poor — who constitute 10 percent of the global population today — but everyone. In addition, the measure captures both higher living standards through income growth and how it is distributed. The Prosperity Gap, outlined in detail in the recently released Atlas of Global Development, captures prosperity within countries and around the world. This blog first presents a measures that looks just at inequality, then a measure that mostly focuses on income growth, and finally the Prosperity Gap.
