The international family of economic and social classifications comprise classifications that have been reviewed and approved as guidelines by the United Nations Statistical Commission or other intergovernmental agencies like the World Health Organisation, International Labour Organisation and World Customs Organisation. These classifications cover topics such as economics, labour, health and education.

Below are some of the main international classifications based on the topic they encompass. More information on statistical classifications as well as their structure and categories can be found on Eurostat’s metadata server - Reference And Management Of Nomenclatures (RAMON).
