Yes, autism is more commonly diagnosed today than it was 20 years ago. The question “Is autism more common today than it was 20 years ago?” is answered by looking at both statistics and diagnostic practices. According to recent CDC data, autism now affects about 1 in 31 children in the U.S.—a significant increase from previous decades. Studies show that autism diagnoses have risen by nearly 800% in the last two decades, with similar trends seen worldwide.
However, this rise does not necessarily mean more people are developing autism. Experts agree that the increase is mainly due to greater awareness, broader diagnostic criteria, improved screening tools, and better access to services. Many children who might have been missed or misdiagnosed years ago are now being identified, especially those with milder symptoms or from historically underdiagnosed groups.
