The multiple and pervasive forms of exclusion remain understudied in the emergent everyday segregation literature mainly centered on a single social dimension from a single-city focus. From mobility surveys compiled together (385,000 respondents and 1,711,000 trips) and covering 60% of Frances population, we explore mismatch in hourly population profiles in 2,572 districts with an intersectional point of view. It is especially in areas with strong increase or decrease of population during the day that hourly profiles are found not only to combine the largest dissimilarities within gender, age and educational subgroups but also to be widely more synchronous among dominates (men, middle-age and high educated groups) than among subordinates subgroups (women, elderly and low educated groups). These intersectional space-time patterns provide empirical keys to broaden the scope of exclusion and segregation literature to the times and places when and where peers are well-placed to join forces.
