Over the past two decades, the number of autism diagnoses has certainly risen, but does this mean autism is more common today than it was 20 years ago? The answer isn’t as simple as it seems.


Better Awareness and Diagnosis

One of the biggest reasons for the increase in autism diagnoses is improved awareness.


More parents, teachers, and doctors are educated about autism today than ever before. This means more children are being diagnosed, including those who may have been overlooked in the past. 


As autism awareness has grown, so has the ability to identify the condition early, leading to more accurate reporting.


Changes in Diagnostic Criteria

The way autism is diagnosed has also evolved. In the past, some forms of autism were missed or misdiagnosed. 


Today, the diagnostic criteria have expanded to include a broader range of behaviors and characteristics. This leads to more children being classified under the autism spectrum, even if their symptoms are mild.


What Does This Mean for Families?

While it may seem like autism is becoming more common, it’s really a reflection of better recognition and understanding. If you or someone you know is seeking autism support, it’s crucial to get the right help at the right time.
