(CNN) – April 2 is World Autism awareness Day and people around the world will be spreading awareness to help eliminate the stigma of autism.
In the U.S. officials say autism has grown slightly more common.
A new report on autism came out Thursday from the Centers for Disease Control and Prevention.
It found that about 1 in 54 U.S. children were identified as having autism in 2016.
That's up from 1 in 59 children in 2014.
To help eliminate the stigma of autism people around the world plan to show support, understanding, and acceptance by taking a selfie wearing something blue and posting it to social media with the hashtag world autism day or light it up blue.
