Countries With The Lowest Rates Of Autism

India and China have the lowest rates of autism in the world, with 1 in 250 people in India and 1 in 186 people in China estimated to be on the autism spectrum. This is significantly lower than the global average and many other countries such as the United States, the United Kingdom, Canada, Australia, Brazil, and South Africa.

The lower prevalence of autism in India and China could be due to a variety of factors. One of these factors could be the availability of resources and services for those on the autism spectrum.

In India, there is a lack of awareness and understanding of autism, and access to specialized services is often limited. In China, there is a stigma surrounding autism and access to services is also limited. Both countries have a long way to go in terms of providing resources and services for those on the autism spectrum.

Countries With The Highest Rates of autism

The United States currently has the highest rate of autism in the world, with an estimated 1 in 36 children on the autism spectrum.

This rate has been steadily increasing over the past few decades, and the CDC estimates that as of 2020, 1 in 59 children in the United States have been identified with autism. Boys are also four times more likely than girls to be diagnosed with autism in the United States.

The United Kingdom has the second highest rate of autism, with an estimated 1 in 100 people on the autism spectrum.

The national autistic society estimates that about 700,000 people in the UK are on the autism spectrum, with more than half of those being children.

Canada, Australia, and Brazil all have similar rates of autism, with 1 in 66, 1 in 100, and 1 in 250 people, respectively, estimated to be on the autism spectrum. In all of these countries, boys are more likely to be diagnosed with autism than girls.

Overall, the prevalence of autism varies widely across countries, and it is important for countries to be aware of the prevalence of autism in their population in order to provide the best possible support and services to those on the autism spectrum.

Autism Demographics: Rates by Gender, Age, and Race

RaceAutism Prevalence In 8-Year-Olds (2018)Percent
White21.2 per 1,0002.1%
Black22.3 per 1,0002.2%
Asian/Pacific Islander22.2 per 1,0002.2%
Hispanic22.5 per 1,0002.3%
Overall23.0 per 1,0002.3%

Autism is estimated to affect 1 in 36 children in the United States, with boys being four times more likely than girls to be diagnosed. Boys are also more likely to be diagnosed at an earlier age than girls, and the average age of diagnosis for boys is 4.3 years compared to 5.3 years for girls.

This pattern is seen across all racial groups, although white and hispanic children are more likely to receive earlier diagnoses than black and asian children.

Research suggests that the gender and racial disparities in the prevalence of autism may be due to a number of factors, such as cultural biases, diagnostic practices, and access to resources and services.

For example, it has been suggested that boys may be more likely to be diagnosed with autism because they are more likely to display behaviors associated with the disorder and they are more likely to receive access to services.

Similarly, cultural biases may lead to racial disparities in the diagnosis of autism, as black and asian children may be less likely to receive a diagnosis due to underlying biases in healthcare.

Overall, it is important to note the disparities in rates of autism by gender and race in order to ensure that all individuals on the autism spectrum receive the support and services they need.

Autism Employment Statistics

You might not have known that only 15% of autistic adults with a college degree are fully employed. Interestingly, 1 in 4 autistic adults are fully employed, and around 21% of young adults on the autism spectrum are currently or were recently employed.
