This book takes a closer look at the societal functions of sports clubs by using the broad range of empirical data of a comparative study. There is a limited amount of up-to-date knowledge on the functions of sports clubs and their potential to promote public health, social cohesion and democratic participation through volunteering and thus contribute to public welfare in European societies. Most of the existing studies are country-specific and therefore do not allow for making comparisons from a cross-national perspective. In light of this, the project ‘Social Inclusion and Volunteering in Sports Clubs in Europe’ (SIVSCE) collected, analysed and discussed comparable data and knowledge across ten European countries and disseminated this knowledge to politicians, sports professionals and sports volunteers in Europe.
