To guide its work toward a "world free of poverty," the World Bank Group in 2013 established two clear goals: end extreme poverty by 2030 and promote shared prosperity. Along with the requirement to pursue these goals sustainably -- economically, environmentally, and socially -- the two goals are comprehensive in nature. They are fully aligned to support the Sustainable Development Goals (SDGs) set by the United Nations to replace the Millennium Development Goals (MDGs). To evaluate progress, the two goals are measured by two overall indicators: a reduction in the global headcount ratio of extreme poverty (the population share of those whose income is below the international poverty line) to 3 percent by 2030, and the promotion of income growth in the bottom 40 (B40) percent of the population in each country.
This Policy Research Note updates the assessment of progress toward these two goals in a sustainable manner. The poverty goal is examined through three lenses: the evolution of income poverty based on the new international poverty line that has been re-estimated at $1.90 a day; an assessment of person-equivalent income poverty, a new intuitive indicator that combines the incidence with the depth of poverty; and a review of the breadth of poverty, recognizing that income shortfalls often coexist with multiple non-income deprivations. The shared prosperity goal is examined on the basis of the latest comparison of (comparable) household data on B40 income growth. As part of its analysis of the two goals, this note also comments on the status of defining and monitoring sustainability in its economic, environmental and social aspects.
