The Classification of Territorial Units for Statistics (NUTS, for the French nomenclature d'unités territoriales statistiques) is a geocode standard for referencing the administrative divisions of countries for statistical purposes. The standard was developed by the European Union.
There are three levels of NUTS defined, with two levels of local administrative units (LAUs). Depending on their size, not all countries have every level of division. One of the most extreme cases is Luxembourg, which has only LAUs; the three NUTS divisions each correspond to the entire country itself.
There are 92 first-level NUTS regions of the European Union, and 240 second-level NUTS regions.
