Objective: The life expectancy of both the mainstream population and of people with intellectual disabilities has increased significantly in the past 100 years. However, there are research gaps regarding the comparative experience of ageing with and without a lifelong intellectual disability, and differences that are evident between metropolitan and rural localities. Methods: The current study examined the main factors that supported or hindered successful ageing for both people with and without lifelong intellectual disability across both metropolitan and rural regions of NSW and Queensland. The project utilised a qualitative design in which 40 semi-structured interviews were undertaken with individuals ageing both with and without an intellectual disability and their carers. The sample was comprised of participants who were still living in their local community and those who had transitioned into a permanent residential aged care placement. The purpose of the interviews was to gauge what different factors were enablers or impediments to the successful ageing process. Key Findings: The paper will present the findings, with a focus upon the social, environmental, political and personal health factors that underpin successful ageing. The key similarities and any differences for individuals both with and without lifelong intellectual disabilities residing in rural and metropolitan areas will be discussed. Conclusions: There is an increasing need for support structures that meet the often complex individual needs of people ageing with an intellectual disability. These models need to be based upon information gained from inclusive research to ensure that the disparate needs of people with intellectual disabilities are met in both rural and metropolitan localities. Learnings from the mainstream ageing communities can further assist in the development of appropriate systems of support. The results have also informed ways in which bridges can be built between disability and aged care policies and practices.
