New-Aquitaine: Urban Units 2015 by Municipalities

The urban unit is a commune or a group of municipalities which includes in its territory a built-up area of at least 2,000 inhabitants where no dwelling is separated from the nearest to more than 200 metres. In addition, each municipality concerned has more than half of its population in this built-up area. If the urban unit extends over several municipalities, all these municipalities form a multi-community or urban agglomeration. If the urban unit extends over a single municipality, it is referred to as an isolated city. Urban units, dated 2010, were established with reference to the population known in the 2007 census.
