World Autism Awareness Day is celebrated on 2 April every year, in order to help share more knowledge on the neurodevelopment disorder, which has affected the lives of many people around the world.

The disorder, characterized by impaired social interaction and verbal and non-verbal communication, and by restricted, repetitive or stereotyped behavior, is often said to affect information processing in the brain.

The prevalence of autism is about 1-2 per 1,000 children in the United States, and it occurs about four times more often in boys than girls. According to a Centers for Disease Control and Prevention report, 20 per 1,000 children in the Unites States are diagnosed with ASD (Autism Spectrum, which also includes Asperger Syndrome and Pervasive Developmental Disorder) as of 2012. The number of children diagnosed with autism has been increasing dramatically since the 1980s.

"World Autism Awareness Day is about more than generating understanding; it is a call to action. I urge all concerned to take part in fostering progress by supporting education programmes, employment opportunities and other measures that help realize our shared vision of a more inclusive world," UN Secretary-General Ban Ki-moon said in his message for the World Autism Awareness Day 2014.
