Why Autism Diagnoses Have Surged Since the ’90s—and What Parents Should Really Know

Autism Rates Are Rising—But So Is Our Understanding

If you’ve heard that autism rates have increased dramatically since the 1990s, you’re absolutely right. Back then, autism was considered rare—affecting roughly 1 in 1,000 children. Today, the number is closer to 1 in 31. For many parents, this can feel overwhelming. Why are so many more children being diagnosed? Is something new causing it?

The truth is far more reassuring than it might seem. The rise in autism diagnoses is not about an epidemic—it’s about recognition, research, and a long-overdue expansion of how we understand neurodevelopment.

What’s Really Behind the Increase in Autism Diagnoses?

1. Broader and More Accurate Diagnostic Criteria

In earlier decades, autism was narrowly defined. Children had to fit a rigid clinical mold to receive a diagnosis. Today, we understand autism as a spectrum—ranging from individuals with significant support needs to those who are highly independent. This expanded definition means more people who were previously overlooked are finally being recognized and supported.

2. Improved Awareness and Early Screening

Awareness of autism has skyrocketed thanks to education, advocacy, and public dialogue. Pediatricians and educators now routinely screen for autism as early as 18 months using evidence-based tools. In the past, these children may have gone undiagnosed or been misdiagnosed.

3. Decreased Stigma and More Inclusive Practices

Families are now more empowered to seek answers and support, especially for children who may not display “classic” autism traits. Girls and children of color—historically underdiagnosed—are also now being more accurately evaluated. The result? A more complete picture of how autism presents across different populations.

3 Persistent Myths About Autism (And the Truth Behind Them)

Myth #1: Vaccines Cause Autism

This is one of the most dangerous and widespread myths. The idea has been extensively studied and repeatedly disproven by decades of scientific research. Vaccines do not cause autism. Autism is a complex neurodevelopmental condition influenced by genetic and prenatal factors—not immunizations.

Myth #2: Autism Is Always Severe

Autism is not one-size-fits-all. It exists on a broad spectrum, which means some individuals may need significant daily support while others live independently and thrive in careers, relationships, and communities. Each person with autism is unique, with their own strengths, challenges, and personality.

Myth #3: Bad Parenting Causes Autism

There is absolutely no evidence that parenting style causes autism. Autism is something a person is born with. It is rooted in brain development and genetics, not upbringing. In fact, informed and compassionate parenting can make a huge difference in how well a child with autism flourishes.

How to Support a Child With Autism—Today and Long Term

Supporting a child with autism starts with understanding who they are—not who others expect them to be. Comprehensive developmental evaluations, tailored support strategies, and family involvement are essential pieces of the puzzle.

For many families, behavioral interventions like ABA therapy in New York play a vital role in helping children build communication, social, and daily living skills. These supports are especially effective when delivered early—but can be beneficial at any age.
