A disability is defined as any impairment that impacts an individuals’ daily tasks or ‘core activities’ (communication, self-care or mobility) and has lasted, or is likely to last, more than 6 months1. Disability encompasses physical, intellectual, psychiatric, sensory and neurological conditions or a combination of these2. The severity of a disability can range from mild (needs no help and has no difficulty with core activities but uses aids or has impairments in other areas) to profound (unable to do or always needs help with core activities)1. In 2012, 7% of children aged 0-17 in Australia were experiencing disability3.

Around two thirds (67%) of Australian children with a disability require assistance with daily activities (e.g. communication, mobility, self-care). Many children with disabilities have learning and social difficulties at school4. In addition to challenges faced by the child, disability impacts the entire family unit. The assistance and care (both formal and informal) of a child with disability often results in parents and/or carers having reduced income, increased expenses, poorer emotional and physical wellbeing and strained relationships4. Significant evidence has supported the effectiveness of early intervention for children with developmental disabilities4.

Across the life span, having a disability is associated with poorer health behaviours and adverse health outcomes5. Further, disability is associated with poorer social engagement and education. These outcomes could be related directly to the disability itself or a result of limited access (due to an individual’s disability) to appropriate information, services and support that foster wellbeing. People with disability have higher rates of mental illness, psychological distress, arthritis, smoking and a range of other health conditions than the general population5.

Given the challenges and needs of children with disability and their families, understanding the proportion of children with disability in particular geographical regions can assist policy makers and service providers in decision making to improve outcomes.

Data Confidentiality

Areas with count values 1 to 4 and where population is less than 50 have been suppressed.

Prior moving averages combine a sequence of 3 or 5 years of data prior to, and including, the selected year. The series are presented as overlapping sequences until the most recent year is included. Moving averages make it possible to combine more years of data to maximize sample size at each point while maintaining data confidentiality.
