Similar limited changes in poverty estimates are observed at the higher lines of $3.65 and $6.85, which are typically used for measuring poverty in lower-middle- and upper-middle-income countries, respectively. The 2011 PPP-based estimates are also available in PIP. Survey coverage for low- and lower-middle-income countries for 2019 is 78.8%. Table 1 Poverty estimates for reference year 2019, changes between September 2022 and March 2023 vintage by region and poverty lines Note: Poverty estimates are not reported for Eastern and Southern Africa and Middle East and North Africa due to a limited survey data coverage of less than 50% of the regional population however, the available data are incorporated into the poverty estimates for Sub-Saharan Africa and the world, respectively. This revision represents 11 million more people living in extreme poverty, largely driven by South Asia (5 million) and the Middle East and North Africa (4 million).
The global poverty headcount ratio at $2.15 is revised slightly up by 0.1 percentage points to 8.5 percent, resulting in a revision in the number of poor people from 648 to 659 million. Table 1 summarizes the revisions to the regional and global poverty estimates between the September 2022 data vintage and the March 2023 data vintage for the 2019 reference year at all three poverty lines. Overall, these changes have resulted in minor revisions in global and regional poverty estimates. This update also incorporates the usual changes to the input data, including revisions to existing welfare distributions, the inclusion of new welfare distributions, and revisions to price, national accounts, and population data used for global poverty monitoring (more details here). In total, 113 new country-years have been added, bringing the total number of surveys to more than 2,100.
These are the regions for which we now have sufficient survey data available during the COVID-19 pandemic. This update includes new regional poverty aggregates in 20 for Latin America and the Caribbean, and in 2020 for Europe and Central Asia, and the group of advanced countries. Global poverty estimates were updated today on the Poverty and Inequality Platform (PIP).
