Urban unit in Ile-de-France according to INSEE

The concept of urban unity is based on the continuity of the building and the number of inhabitants. Urban unit is called a commune or a set of municipalities with a continuous built-up area (no cut of more than 200 meters between two buildings) that has at least 2,000 inhabitants.If the urban unit is located in a single municipality, it is called isolated city. If the urban unit s' extends over several municipalities, and each of these municipalities concentrates more than half of its population in the continuous built-up area, it is called a multi-municipal agglomeration. __Origin__ The zones are created by aggregation of the municipalities of the same urban unit. The contours follow the communal boundaries of the BD Topo. __Partner organisations__ DRIEA IF (Regional and Interdepartmental Directorate for Equipment and #x27;Ile-de-France), DRIEA-IF Headquarters __Links annexes__ * [XML metadata view](http://ogc.geo-ide.developpement-durable.gouv.fr/csw/all-dataset?REQUEST=GetRecordById&SERVICE=CSW&VERSION=2.0.2&RESULTTYPE=results&elementSetName=full&TYPENAMES=gmd:MD_Metadata&OUTPUTSCHEMA=http://www.isotc211.org/2005/gmd&ID=fr-120066022-jdd-260896ac-f678-4347-a408-f1b6e9e905de) [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/d26ca18531dba697db5f80cbca905823c056f281)
