| Statistical concept and methodology | Methodology: The choice of consumption or income for a country is made according to which welfare aggregate is used to estimate extreme poverty in the Poverty and Inequality Platform (PIP). The practice adopted by the World Bank for estimating global and regional poverty is, in principle, to use per capita consumption expenditure as the welfare measure wherever available; and to use income as the welfare measure for countries for which consumption is unavailable. However, in some cases data on consumption may be available but are outdated or not shared with the World Bank for recent survey years. In these cases, if data on income are available, income is used. Whether data are for consumption or income per capita is noted in the footnotes.
Statistical concept(s): Survey mean consumption or income per capita, total population measures the amount of consumption or income per person per day in the population. It is estimated from survey data and expressed in 2021 PPP dollars. |
| Development relevance | The World Bank Group has a goal of promoting shared prosperity within and across countries. Growth is good for the poor and growth in poor countries reflects in improvements in the World Bank’s new shared prosperity measure, the Global Prosperity Gap. |
| Limitations and exceptions | Because household surveys are infrequent in most countries and are not aligned across countries, comparisons across countries or over time should be made with a high degree of caution. |
