Autism Rates by Country in 2021 (which is lowest?)

I know autism is on the rise in the US, and has been for some time, but I wondered what the autism rates by country were around the world.

I decided to research it, and here’s what I found out:

Poland has the absolute lowest rate of autism in the world, followed closely by Taiwan. The next countries with low autism rates, while having significantly higher rates than those 2, include China, Germany, the Netherlands, and Norway. In the US, the rate of autism is 1 in 59, which ranks as #16 worldwide.

But there’s a lot more to know about the countries with the lowest autism rates and the highest.

Surprisingly, the autism rates by country are quite varied. While you can see the entire list at the bottom of this article, we’ll also be exploring how well different countries report instances of autism, and we’ll hear from experts that interpret the data and statistics.

We don’t have all the answers by any means, but we do know the questions. And this post is steering clear of conspiracy theories and just focusing on facts.

So today, we’ll be reviewing the countries with lowest autism rates to see if there are any correlations that could help shed some light on this epidemic. We’ll also look to see if there are any countries with no autism.

If you are a parent of a child with autism, one of the scariest things can be letting them out of your site.

What is autism?

Autism Spectrum Disorder (ASD) is a wide spectrum of symptoms and behavior patterns.

While it is a worldwide epidemic, it certainly hits some countries harder than others. Thus, we’re reviewing the countries with the lowest autism rates.

Often parents and teachers will notice some, but not likely all, of the following symptoms:

  • inability to read social cues
  • OCD
  • sensory issues (often noted by covering their ears)
  • repetitive motor behaviors (such as hand flapping)
  • repeat behaviors
  • struggles with speech
  • being almost completely non-verbal

While many people on the autism spectrum do possess outstanding learning and comprehension skills, over 50% of autistic people have an IQ of under 70. An I.Q between 90 and 110 is considered average.

30% of autistic children are considered non-verbal, meaning they speak very little or in some cases not at all.

About 20% of children on the autism spectrum also have epilepsy.

What is the current autism rate?

In the United States, according to the CDC, 1 in 59 children is on the autism spectrum as of a 2006 survey.

More recent studies indicate a rate of 1 in 45. But in some of the countries with lowest autism rates, that number can be as low as 1 in 3,333 (Poland).

Across the globe, the World Health Organization puts that figure at 1 in 160. The CDC has also seen a 15% increase in autism spectrum disorder diagnosis over the past 2 years.

Since 2004, they have found an incredible 181% increase through 2018.

Check out even more shocking Autism Statistics Worldwide (click to read on my site) in a highly shared post I published earlier.

Is autism on the rise worldwide?

Yes is the short answer.

It’s worth noting that researchers haven’t been tracking autism for decades. In fact, serious tracking didn’t start until 2000.

It’s also worth noting that unlike many other conditions, there isn’t a blood test or scan that can detect autism. So we are relying 100% on doctors and researchers to objectively agree on criteria and diagnose in a consistent manner.

That is to say, it’s probably not very consistent compared to tracking of other diseases and conditions.

That being said, it’s undeniable that autism IS on the rise. The World Health Organization puts the autism rates by country at 1 in 160. The CDC has noted a 15% increase in autism spectrum disorder diagnosis over the past 2 years and a whopping 181% increase from 2004 to 2018.

How common is autism in Japan?

Japan currently has an autism rate of 1 in 55.

That means for every 55 kids born in Japan, 1 will have autism. That’s considered a fairly low rate, so Japan ranks 16th in the countries with the lowest autism rates.

According to census numbers, there are 126,687,575 people currently living in Japan.

We cannot, however, simply divide that number by 55 to get the total number of people with autism. The reason for that is that the rate of autism is ever-increasing.

As I noted above, autism rates have skyrocketed at an overwhelming 181% from 2004 to 2018.

So chances are, the actual number of autism cases in Japan is probably well under 2,310,813. But no doubt, it’s still a large number of people.

What is the rate of autism in Australia?

Australia does make the list of the 15 countries with the lowest rates of autism.

In fact, it comes in #13 with a rate of 1 in 70 people having autism. It’s also worth noting that Autism Spectrum Australia found that rates had increased by 40% in recent years as they had been 1 out if every 100 people back in 2014.

As with much of the developed and developing world, that doesn’t exactly correlate to an actual increase in autism.

No, how autism gets diagnosed and reported is constantly evolving. So while there’s no doubt the autism epidemic is increasing, some of the changes in numbers are just tied to how we track it.

How many children in the world have autism?

Going back to the CDC, 1.7% of the world’s population is on the autism spectrum.

With about 7.5 billion people on the planet, that would have between 75 million and 150 million people being on the autism spectrum.

Since about 26% of the world’s population is age 15 and under, that would mean between 20 and 40 million kids with autism in the world.

What percentage of babies are autistic?

I mentioned above that the CDC reports that 1.7% of the population has autism.

For babies, however, it’s much harder to know if the rates of autism at birth are any different. The reason for that is that autism often isn’t diagnosed until kids are around age 7.

What we do know is that tracking of autism in minority populations has improved dramatically in recent years. Stuart K. Shapira, MD, PhD of the CDC went on to say that

“Autism prevalence among black and Hispanic children is approaching that of white children”.

No doubt that accounts for the increase from 1.5% in 2016.

While 1.5% to 1.7% may sound small, bear in mind that’s across the total population in the United States. That means out of the 327.2 million people in the US, 5.5 million people have autism.

That increase from 1.5% to 1.7% means an additional 600,000 people have been diagnosed with autism just between 2016 and 2018.

What country has the highest rate of autism?

Hong Kong has the highest rate of autism, coming in at a shocking rate of 1 in 27 people!

Of course, it’s worth repeating that not every country reports autism the same way as others, and there could be a margin of error in comparing the results of 2 different countries.

That being said, it’s undeniable that Hong Kong is the leader in autism rates, since the country with the best rate, Poland, has a rate of 1 in 3,333 people, a 123.5% difference!

Can you prevent autism?

There is not a cure for autism.

That being said, there are a lot of opinions on the causes of autism and ways of prevention. states that “one of the best things (an expectant mother) can do is give herself six months or even a year to improve her diet and make better lifestyle choices (before becoming pregnant).

She should consume organically grown grains, vegetables, fruits, nuts, and lean sources of protein.

Laying the foundation by putting herself in optimal shape prior to conceiving will go a long way in minimizing the chance of miscarriage, or developing other complications of pregnancy and delivery.”

They go on to say that “reducing or eliminating the white foods (sugar, white bread, pasta, pizza, bagels), chemical preservatives and processed foods” may help prevent autism.

Lastly, they also recommend improving the gut bacteria which I get into more below.

What is the best therapy for autism?

Brian Udell, MD, is the director of the Child Development Center of America.

He claims that autism is often accompanied by gastrointestinal conditions.

People on the autism spectrum disorder often have:

  • chronic diarrhea
  • abdominal discomfort
  • bloating
  • other nutritional issues
  • food allergies

There is currently no cure for autism or specifically recommended treatment.

However, removing specific food items from the diet and ensuring healthy gut bacteria have been shown to improve the symptoms of autism.

A recent study published by the National Institutes of Health found that a gluten-free diet was effective “in reducing some autism symptoms, and 2 groups of investigators also reported improvement in nonverbal cognition.”

Other parents have tried removing highly allergic food items such as eggs, fish, nuts, dairy, and soy. The best strategy is to eliminate all items in question from the diet.

Then slowly reintroduce them 1 at a time to see the effects.

Healthy eating for all children (click to read my BEST tips) is essential, but this is even more true for kids with autism.

Going back to Brian Udell, MD, he recommends avoiding:

  • heavily processed foods
  • fast food
  • artificial colors and flavors
  • preservatives
  • hormones & antibiotics in meat and dairy

He also recommends omega-3 fatty acids to reduce inflammation and a probiotic with 1.5 to 4 billion bacterial parts to improve gastrointestinal health.

The crucial role Vitamin D deficiency might play with autism

Yet another recent study published by the National Institutes of Health found a link between autism and deficiency in Vitamin D.

They found that “Neonatal (ie: newborns) vitamin D status was significantly associated with the risk of ASD (autism spectrum disorder) and intellectual disability.”

Therefore it stands to reason that both a prenatal vitamin for pregnant women as well as a vitamin D supplement for children might be a good idea. Always check with your doctor first though.

Mama Bird Prenatal Multivitamin (click to see current prices on Amazon Prime) is the best-selling prenatal on Amazon Prime.

It’s an Amazon Choice product with almost 5 stars and over 1000 reviews, so you know this vegan, organic herbal multivitamin blend is outstanding. 1 tablet contains 67% of the recommended daily allowance of Vitamin D.

So now let’s review the . . . 

15 Countries with Lowest Autism Rates

For the purposes of this list and also based on the countries that provide data, this list of countries with lowest autism rates may be leaving out some 3rd world countries which don’t have accurate means of reporting.

See bottom of the page for credits on data on these autism rates by country.

1. Poland – 1 child for every 3,333

2. Taiwan – 1 child for every 2,000

3. China – 1 child for every 435

4. Germany – 1 child for every 263

5. Netherlands – 1 child for every 208

6. Norway – 1 child for every 196

7. Finland – 1 child for every 185

8. Estonia – 1 child for every 167

9. Belgium – 1 child for every 167

10. Singapore – 1 child for every 149

11. Denmark – 1 child for every 145

12. Canada – 1 child for every 94

13. Australia – 1 child for every 70

14. Switzerland – 1 child for every 69

15. Ireland – 1 child for every 65

The United States would have come in #16 (1 in 45) on this list of countries with lowest autism rates had we gone that high.

It’s also interesting to note that not only did South Korea not make the list of countries with lowest autism rates, but, in fact, has one of the highest rates of autism in the world, despite it being highly stigmatized there.

Also interesting is that while China as a whole has a low rate of autism, Hong Kong, arguably the most developed and western city in China, has the highest rate of autism in the world.

While Poland is certainly much lower than many, there probably aren’t any countries with no autism.

What are the immediate takeaways from this list of countries with lowest autism rates?

  • Asian countries dominate the list
  • Northern European countries also dominate the list
  • Generally speaking, the more developed a country, the higher the rate of autism (which could also be tied to better reporting)
  • For conspiracy buffs, it’s interesting to note that Poland, the country with the lowest rates of autism, does, in fact, have mandatory vaccinations
  • That being said, Poland only mandates 11 vaccines, spread out over 20 shots from birth through 7 months of age
  • Compare that the CDCs recommended 15 vaccines in the US spread out over 20 shots from birth through 6 months
  • From a dietary standpoint, it’s interesting to note that the typical Polish meals are spread out over 5 meals instead of 3 with the largest meal (what they call dinner) being around 2pm
  • Europe and parts of Asia also take a much stronger stance against the use of added growth hormones in meat and dairy than The US
  • There are not any countries with no autism

But in the end, there is not conclusive evidence thus far on exactly why some countries have significantly lower rates of autism than others.

Final thoughts

In this post, we took a deep look into the world of autism.

We looked at what autism spectrum disorder is. We looked at autism rates by country and how they have increased and we also touched on some therapies designed to help support children diagnosed with autism.

Specifically, though, we looked at the countries with lowest autism rates, and autism rates by country, and we avoided conspiracy theories and stuck to proven data.

In the world of autism, we are far from having all the answers, but we can certainly ask the questions. And having all the data and facts can help us to ask better questions.

I am not a parent of autistic kids but my wife is a teacher who specializes in working with autistic kids and in my 9 to 5 working with kids, I do see a number of kids on the autism spectrum.

So, while not a complete expert, I am closely connected to that world.
