Where children and young people live can have a substantial impact on their quality of life. Research has shown that communities facing relative disadvantage often experience poorer outcomes in terms of continued engagement with education, opportunities for employment, and overall wellbeing. The presence of locally accessible services, programs and infrastructure that support the positive development of youth and young people can increase access to opportunities and contribute to a reduction in social inequities. Community asset mapping is a strengths-based activity that focuses on identifying, locating, and cataloguing the existing assets within a particular area. The data generated through asset mapping shines a light on the state of service delivery in a particular place at a particular time, and can be used to inform decision-making in a range of areas, including planning for future services or identifying gaps in the system. Understanding the nature of a community’s assets can promote action that centres the community’s strengths, while also revealing areas for potential development. Our teams from Griffith University and Victoria University worked collaboratively to map the community assets in Logan (for children aged 0–15) and Brimbank (for young people aged 15–24), respectively, in order to describe existing assets, explore the current state, test assumptions, and identify opportunities and priorities for action through co-creation with the community.
