Larger Urban Zones (LUZ) in the European Union

Eurostat's urban population statistics  Eurostat, the European Union's statistical agency, has created the concept of Larger Urban Zone (LUZ) in an effort to harmonise definitions of urbanisation in the European Union. These definitions were agreed between Eurostat and the National Statistics Offices of the different countries of the European Union at the occasion of the European Commission's urban audit of 2004. LUZs have been criticised for their insufficient harmonisation of data, which are still collected by national governments within local administrative units, making it sometimes difficult to compare LUZs from different countries.
