Families of which socio-economic status were historically thought to have higher occurrences of autism?

• A. Low-income families
• B. Middle to high-income families
• C. Upper-middle-class families
• D. Working-class families

Answer: (B)

The belief that middle to high-income families historically had higher occurrences of autism is rooted in a combination of factors, including access to healthcare, education, and awareness. Families in these socio-economic groups often had greater access to resources that facilitate early diagnosis and support. This might lead to a higher observed prevalence of autism cases in these populations, primarily because they are more likely to seek out evaluations and treatments.

Furthermore, middle to high-income families generally have better access to information about autism, which can contribute to higher rates of diagnosis as they are more informed about the signs and symptoms and are more likely to engage with healthcare providers regarding their children’s developmental concerns. This does not imply that autism is more prevalent in these families, but rather that the socio-economic status impacts the likelihood of receiving a diagnosis.

In contrast, groups with lower socio-economic status may have barriers such as lack of access to healthcare, education, and information, which can result in underdiagnosis or late diagnosis of autism.
