(24)In accordance with Regulation (EC) No 1059/2003, territorial units should be defined in accordance with the Nomenclature of Territorial Units for Statistics (NUTS) classification. In order to limit the burden on Member States, regional data requirements should not exceed the requirements established by previous Union legislation unless new regional levels have come into existence in the meantime. Consequently, it is appropriate to allow regional statistical data for Germany to be provided for the NUTS 1 territorial units only.
