Autism is quite common, but not as common as dyslexia or ADHD. Asperger’s, on the other hand, is rarer. There are less than 200,000 children diagnosed with it each year. Around 1 in 160 children have it worldwide. Hong Kong is one of the countries with the most autistic children each year. It has a frequency of 372 out of 10,000 children. South Korea has 263 out of 10,000, and the United States has 222 out of 10,000 children. However, in Poland, Taiwan, and China, autism is quite rare. In Poland, only 3 out of 10,000 children are autistic.
