Dataset Direct Download Service (WFS): Urban units of the Yvelines

The concept of urban unity is based on the continuity of the building and the number of inhabitants. An urban unit is a municipality or group of municipalities with a continuous building area (no cut-off of more than 200 metres between two buildings) with at least 2,000 inhabitants. If the urban unit is located in a single municipality, it is referred to as an isolated city. If the urban unit extends over several municipalities, and each of these municipalities concentrates more than half of its population in the continuous built-up area, it is referred to as a multi-communal agglomeration. Urban units, dated 2010, were established with reference to the population known in the 2007 census. The data refers to urban units identified in the Yvelines.
