We examine the gap in registered crime between the children of immigrants and the children of native Swedes. We follow all individuals who completed compulsory schooling during the period 1990-93 in the Stockholm Metropolitan area (N = 63,462) up to their thirties and analyse how family of origin and neighbourhood segregation during adolescence, subsequent to arriving in Sweden, influence the gap in recorded crimes. For males, we are able to explain between half and three-quarters of the gap in crime by reference to parental socio-economic resources and neighbourhood segregation. For females, we can explain even more, sometimes the entire gap. In addition, we tentatively examine the role of co-nationality or culture by comparing the crime rates of randomly chosen pairs of individuals originating from the same country. We find only a small correlation in the crime of individuals who share the same origin, indicating that culture is unlikely to be a strong cause of crime among immigrants.
