This paper examines the participation of minority and majority youth in organized sport based on the Young in Oslo 2015 survey (response rate: 72%, N = 9.774). Four possible explanations of the minoritymajority gap are introduced: (i) culture, (ii) religion, (iii) discrimination/ racism and (iv) class and socio-economic resources. Class and religion are further examined in the paper. Initially, among the boys, there are no differences between the minority and majority groups. When taking socio-economic resources into account, the minority boys have a slightly higher participation rate than the majority boys. Among the girls, the likelihood of participating in sport clubs is considerably lower for those with a minority background than for those with a majority background. The analyses show that socio-economic resources have an effect on both girls and boys and that religious denomination also explains, to some extent, the minority-majority gap that exists among girls.
