2001 Regional Disability Estimates for New South Wales, Australia, Using Spatial Microsimulation

Document Information

Journal Article


Estimating disability levels in older Australians and their demographic and socio-economic profiles is essential for identifying the need for aged care services and for the development and implementation of effective social policy on ageing. Small area estimates are produced from the spatial microsimulation model 'CareMod' which is based on the 1998 ABS Survey of Disability, Ageing and Carers (SDAC; ABS (1999). Disability, Ageing and Carers: User Guide, Australia. Canberra: ABS), and up-rated to 2001. Estimates are generated by reweighting the SDAC confidentialised unit record file to create 'synthetic' datasets for each Statistical Local Area in New South Wales (NSW), Australia. Disability levels and the need for aged care in NSW was determined across a range of age groups. The results show that there is significant variation across NSW in disability levels and the need for aged care services by older persons. With increasing age, the presence of severe or profound disability increases and, as a consequence, this subgroup of aged persons has a greater potential need for high level care. The coastal areas of NSW have a greater requirement of care provision with respect to overall numbers, as a consequence of the greater overall population. However, many inland towns have greater rates of disability amongst the elderly. The research findings will assist in the strategic planning and improved targeting of aged care services, especially in identifying areas of unmet need at the small area level.
