Spatial Units

What is a city? - Spatial units

Data are collected for several levels:

  • A City is a local administrative unit (LAU) where the majority of the population lives in an urban centre of at least 50 000 inhabitants.
  • The Functional Urban Area consists of a city and its commuting zone. (This was formerly known as larger urban zone (LUZ)).
  • The Greater city is an approximation of the urban centre when this stretches far beyond the administrative city boundaries.

For more details on the spatial dimension of cities, see: Regions and cities glossary
