Full ranking
Places are ordered from the highest to the lowest value. Group medians on this site are the middle value of the members with data for the same year; they are not official aggregates.
How this ranking works
Every country is ranked on its value for 2025, the latest period that most countries have, so all values are for the same point in time. Countries without a value for 2025 are left out. Groups and aggregates such as the European Union are not ranked. Values are as published by FAOSTAT; 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.
