The regions are the highest tier of sub-national division in England. Between 1994 and 2011, nine regions had officially devolved functions within Government. While they no longer fulfil this role, they continue to be used for statistical and some administrative purposes. They define areas (constituencies) for the purposes of elections to the European Parliament. Eurostat also uses them to demarcate first level Nomenclature of Territorial Units for Statistics (NUTS) regions ("NUTS 1 regions") within the European Union. The regions generally follow the boundaries of the former standard regions, established in the 1940s for statistical purposes.
