FAO statistics has implemented structured and comprehensive metadata that can be useful not only for statisticians who compile, validate and analyse the data, but also for users who access and use the data. Within FAOSTAT the metadata system enhances understanding of any given data item – by managing the documentation of related concepts and definitions, its source, the history of its values and the methodology used in its collection.

Classifications

To promote consistency and comparability of information at the world level, FAO statistics provides national statistical offices with internationally recognized definitions, concepts and classifications.
