Abstract
This report addresses anti-social behaviour at green spaces in Wales. Using the data available, this report investigates classifying sites and site users. This classification is used to understand specific anti-social behaviours with agent-based modelling. Regression modelling is also used to calculate a site user’s impact on anti-social behaviour, and the scaling behaviour of associated quantities of interest as the number of site visitors increased was examined. Each area of research provides a different lens to understand what is happening at sites across Wales.
