What’s New document, a total of 63 new surveys were added to the PIP database, bringing the total number of surveys to more than 2,200. These new surveys are largely historical data for advanced economies. In addition, two surveys were added for 2019 and 13 more surveys were added for more recent years.. As explained in more detail in the
The new surveys available for the years of the COVID-19 pandemic have increased survey data coverage to 62% of the world’s population in 2020 and 34% in 2021. With this update, poverty estimates are reported for all regions of the world for 2020, except for Sub-Saharan Africa, as well as the Middle East and North Africa. For 2021, regional estimates are now reported for South Asia, and the previously published estimate for Latin America and the Caribbean have been updated.
Table 1 summarizes the revisions to the regional and global poverty estimates between the March 2023 data vintage and the September 2023 data vintage for the 2019 reference year at all three poverty lines.

Note: Poverty estimates in 2019 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. Survey coverage for low- and lower-middle-income countries for 2019 is 81.1%. The 2011 PPP-based estimates are also available in PIP.
Poverty estimates remain virtually unchanged, except for South Asia and Sub-Saharan Africa where there are upward revisions in poverty estimates. For example, the rate of extreme poverty, as measured by the international poverty line of $2.15, increases by 1.9 percentage points to 10.5% for South Asia and by 0.5 percentage points to 35.4% for Sub-Saharan Africa. Globally, extreme poverty is estimated to increase from 8.5% to 9%, representing 41 million more people living in extreme poverty in 2019. India accounts for almost 70% of this global change in extreme poverty (the revisions to the India series are explained in the What’s New document). At the $3.65 poverty line, India accounts for 40% of the slight upward revision of the global poverty rate from 23.6% to 24.1%. At the $6.85 poverty line, virtually no change is observed in global poverty estimates.

Generally, poverty has been falling historically, except during periods of large crises. The 1998 Asian Financial Crisis put a brake on global poverty reduction, conflict increased poverty in the Middle East and North Africa prior to the pandemic, and poverty reduction reversed in South Asia when COVID-19 hit in 2020. COVID-19 did not lead to a significant increase in extreme poverty in East Asia and the Pacific, Europe and Central Asia, Latin America and the Caribbean, and advanced economies in 2020, which all have relatively low levels of extreme poverty. In South Asia, extreme poverty increased by 2.5 percentage points in 2020. However, South Asia experienced a recovery from the COVID-19 pandemic in 2021, with poverty reducing from 13.1% to 10.9%, while Latin America and the Caribbean experienced an uptick in extreme poverty.
For the remaining regions and the world, there is still limited data coverage for the respective pandemic years to report poverty estimates. The World Bank’s Poverty and Shared Prosperity Report (PSPR) includes projections of poverty during COVID-19, and a more detailed discussion of the effects of the pandemic and the role of fiscal policy in mitigating adverse effects.
