The United Nations began World Autism Awareness Day in 2007 to make people more aware of autism as a global health crisis.

Autism is the fastest-growing developmental disability in the world, with some saying that it affects about 1 in every 100 children. Estimates of worldwide autism prevalence are about 70 million, which is an astonishing number. The majority of the children suffering with autism are boys, with boys being about 4 times more likely than girls to develop autism.

World Autism Awareness Day culminates in a series of events worldwide, with past years including:

- Ringing of the New York Stock Exchange opening bell.
- Public service announcements done by many first ladies and dignitaries on radio and television.
- Awareness events in Central Park, New York.

This year's event is bound to be as, if not more, exciting. So, get involved and make a difference in public awareness regarding this devastating developmental disorder. To learn more, visit the official website here.
