Rate of Autism in USA

The United States has been one of the active proponents, along with Great Britain, to perform research especially in epidemiology to find out the accurate number of children affected with Autism. Research has been ongoing, and it showed that for the past couple of years, the rate of Autism in USA has been increasing.

Autism Spectrum disorder (ASD) is a disorder characterized by deficits in social reciprocity, specifically in interaction and communication, and also accompanied by rigidity to routines and repetitive motor behaviors such as stacking, lining up.

History of Autism

In 1943, the first-ever article written regarding Autism was published. The article was entitled “Autistic Disturbances of Affective Contact” and had discussed some of the symptoms that Autistic individuals had.

It was written by Leo Kanner, an Austrian child psychiatrist, who was intrigued by the case of Donald Triplett whom he had seen at Johns Hopkins Hospital in 1938, who was then 5 years old. Dr. Kanner had several sessions with Triplett after their initial meeting in 1938 and was baffled by the symptoms that Triplett was showing.

First Person Diagnosed with Autism

The symptoms shown were likened to that of Schizophrenia but quite different. This being said, Mr. Triplett was named by Doctor Kanner as Case 1 Donald T, making him the first to be diagnosed with Autism.

However, this does not mean that Mr. Triplett is the first person to have this disorder. For centuries that passed, a number of people may have had it but were not given much attention.

Perhaps these individuals were simply deemed as weird and aloof, who was then immediately called outcasts as they had difficulty managing social relationships and preferred to be solitary.

Also, some of them who had severe Autistic tendencies progressed to having Schizophrenia when they reached adulthood. Because of the wide range of symptoms for Autism, it may have been difficult to pinpoint the most common characteristics.

Most especially, these people may have been kept at home by their families to protect the name and image that they have built, as most prominent families would do. These individuals with Autism would even be institutionalized (as it was common in those times) to receive treatment, just as Mr. Donald Triplett’s parents did to him.

Fortunately, his parents decided to bring him back home after a year and brought him to Dr. Leo Kanner. Because of Dr. Kanner’s work and contribution, more and more physicians and professionals took an interest in this type of disorder.

Furthermore, the closure of mental institutions and the shift of study of different disciplines in child psychiatry, psychology and psychoanalysis, contributed much to the furtherance of research and study for this particular subject, Autism.

More information became available as researchers understood more the course and the nature of this disorder.

In the 1960s, there was an increase in children being diagnosed with Autism. Dr. Victor Lotter who worked in the Medical Research Council Social Psychiatry Unit at London’s Institute of Psychiatry, published the first paper in 1966, concerning the epidemiology of Autism in a large population of children. It was stated in the paper that there are 4.5 in 10,000 children who had Autism.

What country has the highest rate of autism?

For the past few decades, the statistics and rates of Autism have been on the rise, not just in the United States, but globally. This has become a hot topic worldwide not just for the medical professionals but the parents who have children with Autism as well.

Curiosity has sparked up their minds which led to this topic becoming one of the most popular finds in internet search engines. So which country landed on the number 1 rank?

According to published articles about Autism rates by country, the small and buzzing country of Hong Kong ranked first with 372 cases of Autism per 10,000 of their population.

This makes everyone wonder why a small country as this would have this number of individuals with Autism.

Many speculations have been circling as to why this small yet developed country has the most number of cases. One of which is the availability of diagnostic and evaluation tools.

Many parents may have sought help as they have increased knowledge of the red flags of Autism which led to more individuals being diagnosed and tallied.

What country has the lowest rate of autism?

In current Autism statistics, Poland ranks as the country with the lowest rate of Autism. The Polish people rejoice in the fact that they rank as the lowest, having only 3 kids with Autism in 10,000 children.

There are certain factors that have to be considered as to why they are only a few in number. One of them could be the lack of available diagnostic tools, or perhaps the awareness of Autism in the country may have not been as hyped up as compared to the United States or Hong Kong.

This would then mean that the urgency of having their kids evaluated may not that be much. This number could also simply indicate that only a few children are affected by this disability. Whatever the reason may be, all of us would hope that it would stay low as much as possible and to have no more cases of it.

Autism statistics 2019

Autism has been prevalent in most countries now and has garnered a lot of interest from medical professionals and the common folk.

Due to this, a number of epidemiologic researches have been done to gain an estimate of the number of people affected with Autism worldwide.

A recent Autism statistic worldwide was published in 2019 and the estimated number of cases of individuals with Autism is already 62 per 10,000 the population globally.

With this increase in number, more educators, therapists and professionals from different disciplines are on the rise as well to help cater the needs of these people.

Autism Rates by Country

Statistics have been conducted worldwide by separate countries to know the current situation and the number of people with Autism.

These studies have been done to monitor the prevalence of Autism and whether there has been a steady or rapid increase over the years.

Listed below are the available data of Autism statistics worldwide, published between the years 2018 and 2019.

Autism statistics for the year 2020 for these countries are not yet available as some researches are still ongoing. Furthermore, countries that are not listed below, have not published their respective statistics and researches in this field.

Country Per 10,000
Hong Kong 372
Denmark 37-280
South Korea 263
United States of America 207
Japan 181
Thailand 150
Switzerland 145
Canada 122
India 100-140
New Zealand 100
United Kingdom 100
United Arab Emirates 90.9
Italy 80
Turkey 80
Vietnam 75.2
Denmark 69
Australia 67
Singapore 67
Northern Ireland 64.1
Belgium 60
Estonia 60
Finland 54
Norway 51
Netherlands 48
Philippines 45
China 19-42
Germany 38
Brazil 27
Pakistan 25.7
Portugal 9.2
Taiwan 5
Poland 3

 Although there seems to be a rapid increase in the rates of Autism in the United States, South Korea still exhibits more cases.

Autism rates by state (US States)

Over 3.5 million Americans are affected by Autism. The rates of Autism have increased as well by 14% in just a span of 2 years.

It has become more prevalent and the escalating number of cases has been alarming. Therefore, government healthcare systems have been established and budgets have been allocated to put more emphasis on catering these individuals with special needs.

Autism statistics have been performed in selected states and listed below are some of the following:

State Number
Alaska <2%
Alabama 1 in 175
Arizona 1 in 63
Arkansas 1 in 66
Colorado 1 in 76
Florida 4.88%
Georgia 1 in 57
Hawaii <2%
Maryland 1 in 52
Minnesota 1 in 44
Missouri 1 in 74
Nebraska <2%
New Jersey 1 in 32
New York 0.7&
North Carolina 1 in 39
North Dakota <2%
Ohio <2%
Rhode Island >4%
South Dakota <2%
Tennessee 1 in 64
Texas 1.54%
Utah 1 in 54
Washington D.C. >4%
Wisconsin 1 in 60

As data showed above, it appears that Florida has the highest rate of Autism in USA while Alabama has the lowest.

The Centers for Disease Control and Prevention (CDC), United States Department of Health and Human Services alongside Autism and Developmental Disabilities Monitoring (ADDM) Network are currently funding and gathering data for the number of individuals with Autism in the United States.

Subsequently, they will be publishing the data they gathered in the middle or end of this year.

Can you prevent autism?

Despite all research and studies made, there is still no prevention for this disorder up to date. The reason for this is that the cause of Autism is still unknown.

Nevertheless, scientists are trying out new angles on how to deal with this matter. A number of them started to venture in genetic engineering to see whether there is a certain pattern or genetic mutations that have happened during conception and pregnancy.

Other areas such as the study of brain function and behavior are still being studied intensively to find definite causes for this disorder.

Is there any Autism Vaccine?

There has been no known vaccine or medication yet to cure Autism. In spite of this being a lifelong developmental disability, a number of these individuals have coped and have been fully integrated into the community.

More so, there are a number of evidence-based treatment methods that have been applied over the several years to alleviate symptoms of Autism and in turn facilitated the achievement of their optimal level of function.

Who is at high risk for autism?

Although there is no known cause for Autism yet, researchers have identified multiple predisposing factors over the years. Here are some of the following factors listed below:

Genetic Factors

  • Firstborn

Some studies found that firstborn children are more likely to be diagnosed with ASD.

  • Twins

Twin studies show that one is diagnosed with Autism, the other is more likely to have it as well. This is more common to identical twins but could also be seen in fraternal twins.

Prenatal and Perinatal Factors:

  • Advanced Parental Age: This has been one of the most common factors found among the parents of children with ASD.
  • Low birth weight
  • Maternal gestational bleeding
  • Gestational diabetes
  • Low APGAR score


Fetal exposure to valproate: An increase of 4.4% risk of Autism has been found in a study when exposed to valproate compared to the 1.5% risk of those who are not exposed.

With these identified, one must now become cautious and extra careful. Pregnancy must be carefully planned, and regular check-ups should be done at a local obstetrician-gynecologist that the baby growing inside of the womb may be monitored.

Vitamins, proper diet and faithful discipline of one’s self are most important to prevent these risks and as well as to keep you and the baby healthy. Remember, prevention is better than cure.


Autism has become one of the most popular developmental disabilities worldwide and it is surprising to see that the number of cases rapidly escalated for just over 50 years.

The rate of Autism in USA started with Donald Triplett as Case 1, and yet there are already millions of cases that are being diagnosed nationwide. If not for the proponents and those who dedicated their lives to study and perform research, most certainly, a proper diagnosis would not have been established until now.

Probably, these individuals would still be treated indifferently by society and be left inside their homes. Much credit and thanks are given not just to the researchers but other healthcare providers as well.

For these professionals are the ones in direct contact and provide up-to-date management and interventions in order for individuals with Autism to gain independence and be integrated fully in society.

With all the information being given to the general public, we must all put into mind that these numbers are not to debilitate us nor to discourage us.

Rather, it should give us understanding and awareness that we may contribute to the welfare of these individuals. Contribution simply means welcoming them in social gatherings and empathizing with them in their struggles.

If we do each of our own parts, then this world will be a better place for them. Not hostile or something to be feared, but a place of love and joy.
