What outdoor spaces are more likely to be used for different activities? In this repository, we share the data we collected and analysed to explore the impact of physical characteristics of outdoor spaces onthe probability of utilization across diverse individuals, considering various age and gender groups. To collect this data we performed a crowdsourcing campaign. We recruited 409 participants from 21 European countries. To ensure a diverse range of outdoor spaces’ physical characteristics, our selection includes a range of spaces such as public squares, open marketplaces, greenspaces, pocket parks, play spaces, and streets, sourced from three European cities: Rotterdam, Barcelona, and Gothenburg. In our experiments, we presented to participants five different outdoor spaces and asked them to indicate to what degree, and why, they consider them suitable for any of the aforementioned activities. In total we collected data for 413 spaces representing 102 public open spaces, 107 streets, 114 greenspaces, 91 pocket parks, and 84 play spaces. In particular this dataset includes: 9700 ratings of outdoor spaces likely use for different activities (Likert scale 1-5) 6388 short explanations of these ratings Each space is assigned a geolocation and a gsv_id which links this location to its corresponding google street view image
