How this ranking works
Every country is ranked on its value for 2024, the latest period that most countries have, so all values are for the same point in time. Countries without a value for 2024 are left out. Groups and aggregates such as the European Union are not ranked. Values are as published by World Bank; the ranking is a plain ordering from the highest to the lowest value and says nothing about whether a high value is good or bad.
