Despite several decades of Sport for All policies, opportunities for sports participation are still unequally divided, with certain socially disadvantaged groups having less access to sports. To reduce this gap, structural efforts are needed. A question that arises is what role nonprofit sports clubs can fulfil in this matter. In this study, first, it is explored how nonprofit sports clubs perceive their role and responsibility towards socially disadvantaged groups and how they act on it. Second, it is investigated which factors predict the presence or absence of efforts from nonprofit sports clubs for lowering barriers. For this second question, we focus on people living in poverty. Data are based on a survey among 580 nonprofit sports clubs throughout Flanders (Belgium). The findings indicate that the human resources capacity of the club is not the main barrier. It is argued that local sports authorities and sports federations have an important part to play in supporting and encouraging sports clubs in terms of social inclusionary policies, for example by instilling awareness.
