Estimates and analysis of unmet housing need across Australia, as developed by the UNSW City Futures Research Centre from 2021 Census data. This interactive resource identifies households in rental stress or facing homelessness across Australia. Data is available at national, state, Statistical Area Level 4 (SA4) and Local Government Area (LGA) level. Future unmet housing need is also projected out to 2041. This project was a partnership between UNSW City Futures Research Centre, Community Housing Industry Association, UNSW Sydney and the University of Sydney.
