Objective To examine sociodemographic characteristics and caring experiences associated with being an older rather than younger carer of an adult with a chronic health condition. Methods The population-based cross-sectional South Australian Health Omnibus survey was administered in 2016. Multiple logistic regression was used to identify sociodemographic characteristics and caring experiences associated with being an older (≥65 years) versus younger (<65 years) carer of one or more adult(s) with a chronic health condition. Results Of 988 survey respondents who self-identified as carers, 198(20%) were 65 years or over. Characteristics associated with being an older carer included having a partner, having poor physical health, being born outside Australia, have no formal qualification, living in a household of 1–2 people, have an annual household income ≤$60,000, and owning one's home. Carer experiences associated with older carer status included providing ≥40 h of care per week, perceived control over caring, and caring for someone with a neurological condition, whereas caring for someone with a mental illness, reporting poor mental health of their own, and providing personal care were inversely associated. Discussion Interventions directed at older carers should consider the increased likelihood that they may be investing large amounts of time in caring for someone with a neurological condition, and be culturally and linguistically diverse.
