This study investigates decision support within the European geographical area. A total of 21 tools have been analysed leading to the identification of a few emerging trends. Predominantly concentrated in the northern part of Europe, these tools aim to assist urban planners in different ways. Findings reveal issues with tools accessibility and a rather weak focus on hard-to-reach groups, including youth. This study underscores the importance of addressing these gaps to ensure inclusivity and effective engagement. Additionally, the study finds a prevailing emphasis on advanced Information and Communication Technology techniques over qualitative data representation, which poses certain limitations to informed decision-making.
