Map Viewing Service (WMS) of the dataset: Urban unit of Cantal according to INSEE

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 built-up 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 called 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.
