The latest World Bank figure for each measure. The tick marks the world figure.

A $20-a-month plan ($240 a year, US list price) against the median household living standard per person in each country. The median is from the latest national household survey (World Bank Poverty and Inequality Platform), revalued from 2021 purchasing-power dollars into US dollars at recent prices and official exchange rates, assuming real living standards have not changed since the survey. Some surveys measure income and others consumption, which includes food people grow and housing they own, so this is a living standard, not cash to spare. Countries with no survey since 2015 or no defensible exchange rate are left blank.
