This research is a study of the differences in duration of waiting time between European and non-European households to obtain social housing, drawing on the housing survey carried out by the French National Institute of Statistics and Economic Studies (INSEE, Paris, 2006). The idea here is to bring to light eventual discrimination against non-European households. We show that these households, all else held constant, spend more time on the waiting lists. Appropriate decomposition techniques enable us to demonstrate that a nonnegligible portion of this gap could well be due to discrimination.
