Many parents ask, “Is autism more common today than it was 20 years ago?” Research shows that autism diagnoses have increased significantly over the past two decades. However, this rise does not necessarily mean that more children are developing autism. Instead, several factors explain the higher numbers.

First, the definition of autism has broadened over time. Today, children across a wider spectrum of abilities—including those with milder social or communication differences—are recognized as autistic. Second, pediatricians and educators are more aware of early signs, leading to earlier screenings and diagnoses. Third, parents and communities are more informed, making it easier for families to seek evaluations and support.

In the past, many children with autism may have been misdiagnosed with other conditions or overlooked entirely. The increase in numbers reflects progress in understanding, rather than a sudden surge in cases.

At Kids n Heart ABA, we believe awareness is a positive step forward. Earlier and more accurate diagnoses mean children can access therapies like ABA that build communication, social, and daily living skills—helping them thrive at every stage.
