Detailed and accurate statistics about the number of people with specific impairments are not easy to obtain, but here are some estimates:
Mental illness / psychiatric disabilities: Around one in every five Australians, or over three million people, experience mental health problems of some kind, with 170,000 experiencing at least one schizophrenic episode, and up to ten per cent experiencing depressive disorders (HREOC’s “National Inquiry into the Human Rights of People with Mental Illness” report, 1993). This includes ten per cent of mothers experiencing postnatal depression (W.A. Disability Services Commission’s “Disability Counts” report, 1997).
Physical disabilities: 2.6 million or 14 percent of Australians have a physical disability of some kind (ABS). This includes, for example, people with respiratory disorders such as asthma, people with neurological disorders such as multiple sclerosis, cerebral palsy and epilepsy, people with musculoskeletal disorders such as arthritis and spinal injuries and people with immunological disorders such as HIV/AIDS, as well as people with other disorders such as diabetes, kidney disease or cancer.
Sensory disabilities: Over one million Australians have a significant hearing impairment, and around 30,000 are totally deaf. Around 300,000 have substantial vision impairment (not correctable by glasses), and around 20,000 are totally blind (Commonwealth Disability Strategy).
Intellectual disabilities: Approximately two per cent of the Australian population, or 400,000 people, have an intellectual impairment (Australian Institute of Health and Welfare, 1997).
