In recent times, sport's responsibility has grown beyond being only Sweden's largest people movement and activating people. Now sport is also expected to contribute to crime prevention and prevent other social problems. Using sport as a method and a kind of gear has in turn given sport other challenges. By using institutional theory, the study wants to highlight the working practices in which nonprofit organizations use in their own associations as well as with other organizations, to promote integration. The study is aimed at basketball associations in socio- economically vulnerable areas. To investigate this, a main issue was formulated and to answer it, two questions were formulated as an aid. An unstructured group interview was conducted consisting of four (4) respondents with different positions and active in sports in the socio- economically vulnerable areas. Four (4) semistructured interviews were also conducted with sports leaders in the basketball associations in the same areas. The results showed that cooperation between the association, school, the Swedish Basketball Federation, the municipality and the district is of utmost importance in the work of integration and other social problems. Different types of projects are also a common practice. The basketball associations generally have the same working practices with the organizations in the surrounding area with certain exceptions that occur within their own associations.
