This site describes the methodology implemented by the World Bank to calculate global and regional poverty rates that are officially reported in the Poverty and Inequality Platform (PIP). The next page summarizes the methodology in non-technical terms using five steps. The summary is followed by five chapters that dig into these steps in detail.

All decisions, assumptions, and protocols involved in these steps and in the chapters that follow are governed by the World Bank’s Global Poverty Working Group, which is composed of staff from the Poverty and Equity Global Practice, the Development Data Group, and the Development Research Group.
