Shared prosperity measures the extent to which economic growth is inclusive by focusing on household consumption or income growth among the poorest population rather than on growth in the average. It is defined as 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 (together with eradicating extreme poverty).
Out of 88 economies for which data was available for 2013-2018, 73 had positive shared prosperity, meaning that the incomes of the poorest 40 percent of the population increased. 53 countries had a positive shared prosperity premium, meaning that the poorest 40 percent grew at a faster rate than the whole population, so growth benefited the poorest more than the entire population.
Average global shared prosperity (growth in the incomes of the poorest 40 percent) was 2.8 percent for 2013-2018. But the gains are uneven: Shared prosperity and shared prosperity premiums are lower on average in fragile and low-income economies than in middle-income economies. Moreover, the global COVID-19 pandemic is likely to reduce shared prosperity and the shared prosperity premium. The Poverty and Shared Prosperity report 2020 includes a detailed analysis of the 2012-2017 shared prosperity data.
Latest shared prosperity data
The latest edition of the Global Database of Shared Prosperity (GDSP) includes the most recent figures on annualized consumption or income growth of the poorest 40 percent of the distribution in 88 countries, which are roughly comparable in terms of time period and interval.
The GDSP is updated once a year in March (with a possibility of a smaller update in September of some years) and is now in its 8th Edition. This edition is anchored to circa 2013-2018, reflecting the latest available data.
