No 47, Global Poverty Monitoring Technical Note Series from The World Bank

Abstract: The September 2025 update to the Poverty and Inequality Platform (PIP) introduces changes to the data underlying the global poverty estimates. This document details the changes to underlying data and the reasons behind them. It also explains the change in methodology used for countries without data, as well as a minor change in how surveys are interpolated. Finally, the regional classification used in PIP has been aligned with the World Bank classification as of July 2025, although users continue to be able to construct their own regional aggregates from the underlying country-level data. Depending on the availability of recent survey data, global and regional poverty estimates are reported up to 2023, together with nowcasts up to 2025. The PIP database now includes 55 new country-years, bringing the total number of distributions to over 2,500 for 172 economies.
