This document details these changes and the methodological reasons behind them. The database now includes 16 new country-years, bringing the total number of surveys to nearly 2,400. This update incorporates new methodologies for measuring global poverty and introduces new indicators of shared prosperity: the Prosperity Gap and the number of economies with high income inequality. It also incorporates two new analytical dashboards: growth incidence curves and poverty decompositions. Depending on the availability of recent survey data, global and regional poverty estimates are reported up to 2022. For the first time, PIP also includes country-level, regional, and global poverty nowcast estimates up to 2024. The September 2024 PIP update presents the poverty and inequality data underlying the forthcoming World Bank’s Poverty, Prosperity, and Planet Report 2024. All authors were with the World Bank at the time of writing. Corresponding authors: Christoph Lakner (clakner@worldbank.org) and Minh C. Nguyen (mnguyen3@worldbank.org). The authors are thankful for comments and guidance received from Deon Filmer, Haishan Fu, and Luis-Felipe Lopez-Calva. We would also like to thank the countless Poverty Economists that have provided data and documentation, and patiently answered our questions. Without them the database of household surveys that underpins the World Bank’s global poverty measures would not exist. The authors gratefully acknowledge financial support from the UK government through the Data and Evidence for Tackling Extreme Poverty (DEEP) Research Programme. This note has been cleared by Umar Serajuddin.
