Research and Statistics on Deafness and Autism
Research has shown that there may be a higher prevalence of autism spectrum disorder (ASD) among individuals who are deaf or hard of hearing compared to the general population. However, the exact prevalence rates vary depending on the study and population being examined.
Here are some statistics on deafness and autism:
​
-
Prevalence of ASD in the general population: According to the Centers for Disease Control and Prevention (CDC), approximately 1 in 54 children in the United States have been identified with ASD.
-
Prevalence of ASD in the deaf and hard of hearing population: Studies have shown that the prevalence of ASD may be higher in individuals who are deaf or hard of hearing. For example, one study found that the prevalence of ASD among deaf and hard-of-hearing individuals was approximately 1 in 59, similar to the general population. However, another study found a higher prevalence of 1 in 38.
-
Challenges in diagnosis: There are unique challenges in diagnosing ASD in individuals who are deaf or hard of hearing, as the symptoms may be different or more difficult to recognize. For example, social communication difficulties may be more difficult to assess in individuals who rely on sign language or other forms of communication.
-
Comorbidity with other conditions: Individuals who are deaf or hard of hearing and have ASD may also have other conditions, such as intellectual disability or attention-deficit/hyperactivity disorder (ADHD).
​
It is important to note that while these statistics provide some insight into the prevalence of ASD in the deaf and hard-of-hearing population, more research is needed to understand the relationship between these two conditions fully.
