April is Autism Awareness Month, a time dedicated to increasing understanding, acceptance, and support for individuals on the autism spectrum. Autism Spectrum Disorder (ASD) affects millions of individuals and families across the United States and around the world.
Autism is a developmental condition that affects how a person communicates, interacts with others, and experiences the world. Because autism exists on a spectrum, every individual has unique strengths, challenges, and needs.
Awareness and understanding help build more supportive communities and ensure that children and adults on the spectrum are treated with dignity, respect, and inclusion.

Estimated prevalence over time:
Experts believe the increase is largely due to improved awareness, better screening, expanded diagnostic criteria, and earlier identification.
Autism is diagnosed much more frequently in boys.
This difference is partly because autism symptoms may appear differently in girls, making them historically underdiagnosed.
Autism prevalence varies widely depending on location and detection practices.
Among CDC monitoring areas:
Experts say the differences usually reflect:
Autism can often be identified in early childhood.
Research shows that developmental differences may be noticed as early as 18 to 24 months of age. Early screening and early intervention programs can help children develop important communication, behavioral, and learning skills.
Autism is a spectrum condition, meaning individuals experience it in different ways.
Among children with autism:
Each autistic individual has their own abilities, personality, and perspective.
Autism is part of a larger group of conditions.
These include:

Greater awareness helps ensure that autistic individuals are supported and valued in schools, workplaces, and communities.
During Autism Awareness Month, we also remember the lives of children on the autism spectrum who are no longer with us. Every child leaves a lasting impact on the lives of those who loved them.
Their stories continue to inspire greater compassion, understanding, and advocacy.
