About
The World Bank's Poverty and Inequality Platform: for each country and household survey, the mean and median daily income or consumption per person in 2021 PPP dollars, the Gini index, each decile's share, and the share of people below a poverty line the slice chooses (3.00 a day by default, the international extreme poverty line). Income and consumption surveys are not comparable, and neither are rows with different survey_comparability values. Some countries have separate urban and rural rows (reporting_level). With fill_gaps the API adds estimates for the years between surveys.
