世界银行-2025年6月贫困与不平等平台（PIP）更新（英）-2025.6_50页_1mb

The June 2025 update of the World Bank's Poverty and Inequality Platform (PIP) introduces major changes to underlying data and methodologies for global poverty estimates. The adoption of 2021 Purchasing Power Parity (PPP) values increases global poverty lines from US$2.15 to US$3.00, from US$3.65 to US$4.20, and from US$6.85 to US$8.30. These adjustments reflect updated national poverty lines and address price variations, though some exceptions were retained for specific countries due to data quality issues.

India's data updates, including a shift to modified mixed recall periods and welfare aggregates, shift poverty estimates by reducing extreme poverty rates but affecting comparability with historical data. The introduction of 81 new country-years (totaling over 2460 data points) and the removal of 7 outdated country-years enhances global coverage but requires careful interpretation due to shifts in methodologies and data sources.

Revisions affect regional and global poverty trends, particularly in Sub-Saharan Africa, where data coverage gaps limit nowcast accuracy. Other technical changes include updates to consumer price indices, national accounts data, and spatial deflation for welfare aggregates, ensuring comparability across countries and time periods. Poverty estimates are now reported up to 2023 with nowcasts to 2025, reflecting improved but still uncertain data for regions with limited recent surveys.
