Segregation studies have been surprisingly silent about age and life course. Yet many social and ethnic inequalities are reproduced throughout the life course and intersect with age, and moreover are also highly spatialised. Drawing on individual-level register data for Amsterdam’s metropolitan area aggregated at the neighbourhood level, this contribution charts the levels of segregation of age over time and the intersections between age and migration backgrounds and income. Also, it gauges the patterns of income and ethnic segregation for different age groups of children. The chapter demonstrates that generally age segregation is not very high, but from retirement age segregation levels rise steeply. It also reveals that age segregation is highly differentiated across ethnic categories and class. This shows that some of the social and ethnic inequalities in society manifest themselves only specifically for some age groups.
