Measuring social infrastructure shines a light on the places that power community connection.

When it comes to social infrastructure, we measure the location and spread of the physical places and spaces that support social connection.

We map locations of social infrastructure in each SA1 neighbourhood – areas of around 200 to 800 residents across metro, regional and remote communities.

We calculate the places and spaces in each social infrastructure category, and overall to create a neighbourhood-level density score.

We compare density with bridging ties to reveal gaps and strengths, and point to where investment can build more connected, resilient communities.
Sociabli brings together national data sources and world-leading research to measure social infrastructure.
This enables us to:
Measuring social infrastructure helps us understand which shared places and spaces matter most, which is good for everyone.
