In the Netherlands, approximately 700,000 individuals do not feel socially included in the sports sector (Ministerie van Algemene Zaken, 2014). Sports participation offers physical, mental and social health benefits (Vuori, 1987). Public sports facilities, defined as publicly available built facilities or areas designed to encourage physical activity (Limstrand, 2008), should enable everyone to participate. However, a significant gap exists between ideal utilisation and actual utilisation, where certain groups are underrepresented (Gao et al., 2022). Girls aged nine to twelve are particularly underrepresented in sports (Collins & Kay, 2014) and more likely to be socially excluded from public spaces (Zimm, 2019). This suggests a mismatch between public outdoor sports facilities and the needs of this group. This research aims to address this mismatch by answering the following research question: ‘What measures can municipalities take to make public outdoor sporting facilities more socially inclusive for girls aged nine to twelve?’. A literature review will identify factors influencing social inclusion of public sports facilities. After identification of factors, Beweegpark Kraaiennest is introduced and assessed through observations and discussions with girls aged nine to twelve based on the photovoice technique to evaluate the current level of social inclusion and utilisation, highlighting areas of improvement of the public sports facility. These insights inform a focus group and interviews, where professionals share their perspectives on the topics to create concrete and actionable measures. Ultimately, this research aims to provide municipalities with practical measures to enhance the social inclusion of public outdoor sports facilities for girls aged nine to twelve, offering valuable guidance for municipal policymakers in the sports sector and addressing a gap in literature about increasing social inclusion of sports facilities.
