The country with the highest rate of diagnosed autism in the world is Qatar, and the country with the lowest rate is France. Around 4 times as many boys have autism as girls. The rate of autism in the U.S. went from 1 in 150 in 2000 to 1 in 100 in 2022.
It is estimated that 1 in 100 people in Australia have Autism. In 2018 there were 205,200 Australians with Autism, a 25.1% increase from the 164,000 in 2015 (Source: ABS SDAC 2018– Autism in Australia). This means that if you have Autism you are not alone.
Autism prevalence is reported to be highest among non-Hispanic white children, lower in Hispanic and African American/black children, and highly variable in Asian/Pacific Islanders. More comorbid intellectual disability and delays in expressive language have been observed among Hispanic and African American children.
In Northern Europe recent studies (since 1999) found an average ASD prevalence rate of 18.8/10,000. In the United States and Canada recent studies (since 2000) found an average ASD prevalence rate of 21.6/10,000. In China there was an average ASD prevalence rate of 11.6/10,000.
ASD occurs in all racial, ethnic, and socioeconomic groups. It is more than 4 times more common among boys than among girls.
1 in 100 children are diagnosed with autism spectrum disorder as of 2021. Autism prevalence has increased 178% since 2000. The country with the highest rate of diagnosed autism in the world is Qatar, and the country with the lowest rate is France.
Long-term research that involved following a group of individuals with autism for two decades indicates that the average life expectancy for some autistic people is about 39 years. Furthermore, this population generally succumbed to health complications about 20 years earlier than individuals who do not have autism.
The extreme male brain theory posits that it is an overdevelopment in the male traits of cognition that causes ASD patients to over-systematize, leading to a breakdown of verbal and social capacities. Some studies have found correlations between fetal testosterone levels and ASD.
So, why are the rates of autism increasing? Greater awareness. The primary reason that the rates of autism have increased is greater awareness of autism.
Autism is not an illness
It means your brain works in a different way from other people. It's something you're born with. Signs of autism might be noticed when you're very young, or not until you're older. If you're autistic, you're autistic your whole life.
Autism is strongly genetic
The risk of having another affected child is estimated to be around 1 in 5. Family members of a person with autism also tend to have higher rates of autistic traits.
Although the exact cause of autism is still unknown, there is evidence to suggest that genetics play a significant role. Since autism is less prevalent in females, autism was always thought to be passed down from the mother. However, research suggests that autism genes are usually inherited from the father.
Some argue that autism's prevalence is rising because of environmental causes like vaccines. There is no evidence, though, for that explanation. Others argue that the rate is increasing because of the rising age of parents, especially fathers.
If someone in your family has autism spectrum disorder (ASD), you may be more likely to have a child with ASD. ASD can look very different from person to person, so taking a careful family health history can be important for early diagnosis.
SUMMERS: Donald Triplett was the first person to be diagnosed with autism. He died last week after a long fight with cancer. He was 89 years old.
Because autism is a developmental difference, people with autism can often find it difficult to learn and manage everyday tasks, like taking a shower, getting dressed, brushing their teeth and packing their school bag; or daily chores like making their bed, or setting the table.
Progress has been made toward understanding different environmental risk factors, and the clearest evidence involves events before and during birth, such as: Advanced parental age at time of conception. Prenatal exposure to air pollution or certain pesticides. Maternal obesity, diabetes, or immune system disorders.
Colorado, New York, Maryland, and Connecticut typically rank high as the states providing the most benefits to autistic people in all age groups.
Autistic people may act in ways that are seen as disturbing and impolite by strict Japanese standards. As a result, according to one study, autism is stigmatized to a greater degree in Japan than in the United States (Atherton et al., 2023).
Staying at home with parents or other relatives: From the limited research that exists, it is fair to say that well over half of autistic adults live with parents or other family members (siblings, cousins, aunts, and uncles, for example).
We found that Colorado, Massachusetts, and New Jersey are the most supportive states overall. On the other end of the scale, West Virginia, New Mexico, and Tennessee are the least supportive.
Results from Jilin City, where both mainstream and special school data were available, revealed a similar prevalence of autism in China to the West, at around 1%.
