IRIS, the smallest French statistical unit, is the level of detail recommended for many local market data studies. IRIS divides the country into units of roughly equal population (2,000 inhabitants) for statistical analysis. Municipalities with fewer than 5,000 inhabitants are not divided. Metropolitan France includes a total of more than 50,000 IRIS.
