Contours... Iris® France

Municipalities with at least 10 000 inhabitants and most municipalities with 5,000 to 10 000 inhabitants are divided into IRIS. This division, which is the basis for the dissemination of sub-communal statistics, constitutes a partition of the territory of these communes into “neighbourhoods” with a population of about 2,000 inhabitants. France has around 15,500 IRIS, of which more than 750 are for the Doms. Some overseas communities also have an IRIS split. By extension, in order to cover the entire territory, each of the municipalities of France not cut into IRIS is treated as an IRIS. This division was drawn up in partnership with local partners, in particular the municipalities, in accordance with precise rules defined in consultation with the Commission Nationale Informatique et Libertés (CNIL). It is constructed on the basis of geographical and statistical criteria and, as far as possible, each IRIS must be homogeneous in terms of habitat. IRIS offers the most developed tool to date to describe the internal structure of more than 1,900 municipalities with at least 5,000 inhabitants.
