Shared Prosperity: Monitoring Inclusive Growth

Shared prosperity measures the extent to which economic growth is inclusive by focusing on household consumption or income growth among the poorest population relative to the population as whole. It is the annualized growth rate in the average consumption or income per capita of the poorest 40 percent (the bottom 40) of the population in a country. Promoting shared prosperity is one of the goals of the World Bank Group, along with eradicating extreme poverty. Because this indicator monitors the progress of the bottom 40 and how the less well-off can benefit from economic growth, it is relevant even in higher-income countries, where extreme poverty is much lower.^[1] The new global shared prosperity gap, also monitors growth among the poorest member of the population.

The November 2023 update of the Global Database of Shared Prosperity (GDSP) is the 12th edition of the database since 2014. This new edition includes shared prosperity data for 80 of the world’s economies in 2019, which are roughly comparable for circa 2015-2020, revising figures published in April 2023.

_{[1]  The GDSP is updated in line with the updates to the poverty estimates. A major update to the GDSP happens around March of every year with a possibility of a smaller update in September on some years.}

The number of economies^[2] included in the GDSP depends on the availability of household surveys in the World Bank’s Global Monitoring Database (GMD) as of November 2023.^[3] Shared prosperity is harder to monitor than global poverty. Whereas one household survey is needed to compute poverty, two comparable household surveys are needed to compute shared prosperity. Moreover, these surveys must be conducted around the same years in all economies to measure shared prosperity for roughly the same period. These stricter requirements mean shared prosperity cannot be measured in some of the most deprived economies, which often lack sufficient survey data (a more detailed discussion can be found here). Table 1 below shows how GDSP coverage varies between updates.^[4]

_{[3] The Global Monitoring Database (GMD) is the World Bank’s repository of multitopic income and expenditure household surveys used to monitor global poverty and shared prosperity. The household survey data are typically collected by national statistical offices in each country, and then compiled, processed, and harmonized by the Data for Goals (D4G) team in the Poverty Global Practice.}

_{[4] The largest number of economies covered was in the fourth edition of the GDSP in 2017 (which was used in World Bank, 2020), with 93 economies.}

Survey data are selected according to two criteria: (i) to match the time periods as closely as possible across all countries, while including the most recent data; and (ii) to ensure the widest possible coverage of countries, across regions and income levels. Comparability is assessed according to the database available here. Although 168 countries have an international poverty estimate in the World Bank’s Poverty and Inequality Platform (PIP), significantly fewer have a shared prosperity estimate due to the more stringent data requirements referenced above.

Overall, the GDSP now includes coverage for approximately 4.4 billion people, around 57 percent of the world’s population in 2019. This is lower than the 74 percent coverage achieved in the 11th edition due to revised poverty estimates for India which produced breaks in comparability with earlier surveys. (See Section 3 of Aron et al. 2023 for a more detailed description of these revisions).  (Table 2).

Number of economies with poverty rate counts economies that reported poverty estimates in 2012 or later. SP = shared prosperity indicator. Averages across economies are simple averages, not population weighted.}

The Team

The Global Database on Shared Prosperity was created by the Global Poverty Working Group (GPWG), an interdisciplinary technical working group established to improve the quality and frequency of poverty and inequality data, comprising members from the Poverty and Equity Global Practice and the Development Economics Vice Presidency Data Group (DECDG) and Research Group (DECRG).

Data Source

The Global Monitoring Database (GMD) is the World Bank’s repository of multitopic income and expenditure household surveys used to monitor global poverty and shared prosperity. The household survey data are typically collected by national statistical offices in each country, and then compiled, processed, and harmonized. The process is coordinated by the Data for Goals (D4G) team and supported by the six regional statistics teams in the Poverty and Equity Global Practice. The Global Poverty & Inequality Data Team (GPID) in the Development Economics Data Group (DECDG) also contributes historical data from before 1990 and recent survey data from the Luxemburg Income Study (LIS). Selected variables have been harmonized to the extent possible such that levels and trends in poverty and other key sociodemographic attributes can be reasonably compared across and within countries over time. The GMD’s harmonized microdata are currently used in the Poverty and Inequality Platform (PIP), the World Bank’s Multidimensional Poverty Measure (MPM), the Global Database of Shared Prosperity (GDSP), and Poverty and Shared Prosperity Reports. Additional information on the latest country data can be found in Castaneda et al., 2022.
