Autism spectrum disorder (ASD) is a developmental disorder characterised by symptoms evident from early childhood. The number of people with autism in Australia has increased in recent years, with 290,900 autistic Australians in 2022, representing 1.1% of the population. This is up from 0.8% in 2018 and 0.08% in 2015. The increase in prevalence rates is likely due to increased awareness and understanding of autism, with resultant changes to diagnostic criteria, rather than a rise in autism itself. This increase in diagnosis is particularly notable among previously under-recognised groups, including women and girls, and older Australians aged 60+.

Autism prevalence in Australia: 1 in 40, or 290,900 Australians in 2022
Autism Spectrum Disorder (ASD) is a persistent developmental disorder that affects how individuals interact with their environment and others around them. It is characterised by symptoms evident from early childhood, and every person experiences autism differently. The term "spectrum" refers to the wide range of characteristics, skills, and abilities that people with autism may possess. While autism is most commonly identified in children and young people, it is important to note that it can be diagnosed at any age.
In Australia, the prevalence of autism has been increasing over time. According to the 2022 Survey of Disability, Ageing and Carers (SDAC), there were approximately 290,900 autistic people in Australia, representing 1.1% of the population. This is a notable increase from 2018, when the prevalence rate was 0.8%. The increase in prevalence is attributed to factors such as growing awareness about autism, changes to diagnostic criteria, and better identification of autism characteristics.
The prevalence of autism varies across different age groups, with a peak in the 10-14 year age group. Children aged between 10 and 14 were found to have the highest occurrence rate of autism, after which the number of people identifying as being on the spectrum starts to decline. This variation could be due to changes in diagnostic criteria over time, as well as increased awareness and understanding of autism, leading to better identification.
It is estimated that 1 in 40 Australians are on the autism spectrum, highlighting the significance of supporting and understanding autistic individuals and their families. This estimate is based on the most recent studies conducted in Australia and other western nations, indicating that the prevalence of autism in Australia is higher than previously estimated. The increase in prevalence does not necessarily indicate a rise in autism cases but rather improved awareness and diagnostic capabilities among health professionals.
The early diagnosis of autism is particularly beneficial, as it can provide access to targeted supports and enhance social and educational growth for children. For adults, a diagnosis can lead to a more fulfilling and supported life, fostering deeper and more meaningful connections. It is crucial to recognise that autism is not a disease or illness, and individuals on the spectrum may require varying levels of support and have unique skills and capabilities.

Autism in Australia by age: 83% under 25, peaks at 10-14 years old
As of 2022, approximately 585,200 Australians (or 1 in 39 Australians) are on the autism spectrum, according to the Australian Bureau of Statistics. This figure is likely an undercount, as it does not include individuals with autism who have not been formally diagnosed or those who choose not to disclose their diagnosis.
When examined by age, the data reveals that autism is prevalent across all age groups in Australia, but it is most common among younger individuals, especially those below 25 years old, who make up 83% of the autistic population. Within this younger cohort, the prevalence of autism peaks during the formative years of childhood, with the highest proportion of autistic individuals aged 10 to 14.
During this peak range of 10 to 14 years old, the rate of autism diagnosis is notably higher among boys and men than girls and women. This gender disparity is a consistent trend observed across all age groups in Australia. For every female on the autism spectrum, there are approximately three males with autism, reflecting a similar pattern seen in global autism statistics.
The high prevalence of autism among those under 25 years old underscores the importance of early diagnosis, intervention, and support for autistic individuals during their formative years. This critical period can greatly influence their development, well-being, and ability to lead fulfilling lives as they transition into adulthood.
While the data provides valuable insights into the age distribution of autism in Australia, it is worth noting that autism is a lifelong condition that affects people of all ages. As such, it is crucial to ensure that support services, accommodations, and understanding are available and accessible to autistic individuals throughout their lives.

Autism diagnosis in Australia: increased awareness, changing criteria
The number of people with autism in Australia has increased considerably in recent years, with a reported 290,900 autistic people in the country in 2022, representing 1.1% of the population. This figure is up from 0.8% in 2018, when there were 205,200 autistic people in Australia. The increase in prevalence rates does not necessarily indicate a rise in autism itself, but rather increased awareness and an enhancement in health professionals' ability to recognise and diagnose the condition.
Autism Spectrum Disorder (ASD) is a persistent developmental disorder characterised by differences in social communication and interaction, as well as restricted, repetitive patterns of behaviour. It is referred to as a 'spectrum' due to the wide range of characteristics, skills, and abilities that different autistic people exhibit. The unique combination of these traits means that no two autistic people are affected in the same way.
The increase in autism diagnoses in Australia can be attributed to several factors, including growing awareness and changing diagnostic criteria. Historically, assessment tools and training for autism diagnosis have been informed by an understanding of autism as it presents in males, with research and awareness of autism in females increasing more recently. This has likely contributed to more accurate diagnoses, particularly among previously under-recognised groups such as females and older Australians aged 60+. Changes to the Diagnostic and Statistical Manual (DSM) criteria over time, including updates in 1994 and 2013, have also influenced diagnosis rates, resulting in more people being identified as autistic.
The Survey of Disability, Ageing and Carers (SDAC) in 2018 revealed that autism was most prevalent among children and young people, with 83% of autistic individuals aged under 25. This trend was also observed in 2009, 2012, and 2015, reflecting a general increase in diagnoses for school-aged children. The peak occurrence rate was found in the 10-14 age group, with a decline observed in the late teens and beyond. This decline may be attributed to various factors, including coping strategies, intervention therapies, and limited connection with the autistic community, which may lead some individuals to no longer identify as autistic as they mature.

Autism in Australia by gender: males more likely than females 3.5 times
Autism spectrum disorder (ASD) is a persistent developmental disorder with symptoms evident from early childhood. The prevalence of autism in Australia has increased considerably in recent years, with the number rising from 64,400 people in 2009 to 164,000 in 2015. This represents an overall prevalence rate of 0.7%, or about 1 in 150 people.
Autism is most commonly identified in children and young people, with 83% of autistic individuals aged under 25. The prevalence of autism varies by age, with a peak in the 10-14 age group and a decline beginning in the late teens. This is likely due to a variety of factors, including increased awareness of autism, changes to diagnostic criteria, and the development of coping strategies as individuals mature.
One notable aspect of autism prevalence in Australia is the gender disparity. In 2022, males were over twice as likely to be autistic than females. This disparity has decreased since 2018, when males were over three times as likely to be autistic than females, with a male-to-female ratio of approximately 3:1. The decrease in the gender disparity is likely influenced by increased research and awareness of autism in females, leading to more accurate diagnoses.
The increase in autism prevalence in Australia highlights the importance of supporting and understanding autistic individuals and their families, who represent a significant proportion of the Australian community. Early diagnosis and access to targeted support services are crucial for enhancing social and educational growth and fostering a more inclusive society.

Autism support in Australia: 68.9% need support in communication, self-care, mobility
Australia has seen a general increase in the prevalence of autism diagnoses over time. In 2015, an estimated 164,000 people in Australia had autism, representing an overall prevalence rate of 0.7% or about 1 in 150 people. However, more recent estimates suggest that at least 1 in 40 Australians are on the autism spectrum, translating to approximately 675,000 individuals. This increase is attributed to heightened awareness, improved diagnostic criteria, and enhanced recognition among previously under-diagnosed groups, including females and older adults.
The Australian government provides various support services and schemes to assist individuals on the autism spectrum and their families. One prominent initiative is the National Disability Insurance Scheme (NDIS), which offers support to individuals with autism to improve their developmental outcomes and reduce their need for future assistance. For those over seven, the NDIS pathway may include funding for speech therapy, occupational therapy, behavioural support, and aids like communication devices. Medicare also plays a crucial role in supporting individuals with autism and their families, offering rebates for sessions with allied health professionals through specific programs.
The Helping Children with Autism (HCWA) treatment plan is another initiative that provides children with access to up to 20 sessions with professionals like speech therapists and occupational therapists until they turn 15. Additionally, organisations like Amaze in Victoria offer information and support services to individuals on the autism spectrum, their families, and carers, helping them navigate the available resources and understand autism spectrum disorder (ASD).
Autism spectrum disorder (ASD) is characterised by a range of behaviours and symptoms that can vary in intensity and impact on an individual's day-to-day life. Core activity limitations, such as needing help with communication, mobility, and self-care, are prevalent among individuals with autism. In fact, around 58% of people with autism experience severe or profound restrictions in communication, while 52% face profound or severe mobility limitations. Additionally, about 91% of individuals with autism sometimes or always require assistance with interpersonal interactions and relationships.
Support services for autism in Australia recognise the diversity within the autism spectrum and aim to address the overlapping challenges faced by specific groups, such as autistic Aboriginal individuals or those in the LGBTIQA+ community. These strategies emphasise the importance of understanding unique communication styles, sensory processing sensitivities, and the barriers experienced by these groups, fostering their inclusion in all aspects of life. By prioritising inclusive design, improved transportation options, and public awareness campaigns, Australia demonstrates a strong commitment to empowering autistic individuals and creating a more inclusive society.
