Sur ce « maillon élémentaire » est pratiquée la collecte de données statistiques et démographiques. Ces données sont ensuite analysées et les résultats publiés par l'INSEE.La France compte 50 800 IRIS, dont 700 dans les DOM répartis comme suit:16 100 IRIS, dont 650 dans les DOM, issus du découpage des communes de plus de 10 000 habitants, et la plupart des communes de 5 000 à 10 000 habitants,34 800 IRIS, constitués par les communes non-découpées.Les IRIS se déclinent en trois types de zones :IRIS d'habitat : IRIS dont la population se situe entre 1 800 et 5 000 habitants ; ils sont homogènes quant au type d'habitat ;IRIS d'activité : IRIS regroupant plus de 1 000 salariés et comptent deux fois plus d'emplois salariés que de population résidente ;IRIS divers : IRIS de superficie importante à usage particulier (bois, parcs, zones portuaires...).Plus de 90% des IRIS sont des IRIS d\u2019habitat, 5% des IRIS d\u2019activité.", "geometryType": "esriGeometryPolygon", "sourceSpatialReference": { "wkid": 102110, "latestWkid": 2154, "xyTolerance": 0.001, "zTolerance": 0.001,
