This project updates the Queensland Rental Vulnerability Index, first commissioned by Tenants Queensland in 2016 to help plan the delivery of tenant advice services by the Queensland Statewide Tenant Advice and Referral Service (QSTARS). The project defines 'rental vulnerability' as the vulnerability of persons to problems that may make their rental housing unaffordable, insecure or inappropriate, and which therefore indicates a need for tenant advice. Thirteen indicators of rental vulnerability are identified, in two broad groups: 'housing indicators' and 'people indicators'. All the indicators are subject to a principal component analysis to create the rental vulnerability index (RVI). Each of the indicators is also mapped separately. The update uses 2021 Census data and recent state government administrative data.
