The proposed project will look at the social infrastructure and policy needs for an active ageing Australian society. It aligns with the Institute priority area of Economy and Policy, specifically on housing, aged care and related planning policies. It will achieve this by extending a Population Ageing Matrix methodology developed by Atkins  (based on 2001-2011 Census data). It consists of a spatialised Census and public services data on aged care to identify recent and likely future ageing dynamics across local areas and allow more targeted policy responses. This will be further enhanced by a qualitative policy review focusing on housing, transport/connectivity, and care/welfare policies at the state/territory levels and three local government case studies. A spatialised and trend-based profiling will incorporate Australian Census time-series data (2006, 2011, 2016) to gauge the level and rate of ageing at the local level (SA2) as first suggested by Atkins, but further distinguishing small areas by degree of disadvantage and local demand for care. This will be matched with services and amenities data, e.g. Department of Social Services’ annual residential aged care allocations will be used to determine existing supply of care. Data on propensity of using different modes of transport in local areas will be used to indicate older people’s ability to live independently. The trend changes will also be used to indicate the likely future social infrastructure needs for an active ageing society at the SA2 scale across Australia. A time-series profiling showing demographic change and service accessibility will be mapped and be made openly accessible via City Futures’ CityViz platforms. A qualitative policy review will focus on housing, transport/connectivity, and care/welfare policies. This will be done at the State/Territory level (with Federal policies considered where appropriate) and three local government case studies: City of Sydney for a higher-density context, Port Macquarie-Hastings Council for a retirement destination context, and Dubbo Regional Council for a depopulation/rapidly ageing context.
