What this topic does not measure
Poverty lines, inequality and aid received are published here as context rather than as keys, often because they cover fewer countries or are measured too rarely. Development is also not the same as economic size or growth, which belong to Economy & Innovation.
How the Development & Human Capital standing is decided
A standing is this site’s ordering, named with its edition — never a publisher’s rank. 3 key statistics vote, one vote each; every country’s published value becomes a place within that key’s own field, the places are averaged, and the average is never published. A country needs 2 of the 3 keys to be placed.
