Unequal Access: Exploring the Role of Socioeconomic, Racial, and Geographic Factors in Autism and Speech Impairment Services in California

For many families, a diagnosis of Autism Spectrum Disorder (ASD) or a speech impairment can provide crucial support for many families, but access to these services can be limited by systemic barriers.ASD currently affects about 1 in 36 children in the United States, with even higher rates reported in California (Centers for Disease Control and Prevention [CDC], 2023).Many children with ASD also experience speech impairments, which complicate their ability to communicate and engage with peers.These impairments, including difficulties with sound production, are common in school-aged children, with estimates ranging from 2.3% to 24.6% (American Speech-Language-Hearing Association [ASHA], n.d.).Socioeconomic factors, such as median household income, interact with racial and geographic disparities, including prenatal care access and rural classification, to hinder early diagnosis and intervention.Minority communities often face more challenges due to biases and language barriers, delaying critical support.Additionally, I am looking into the role of early prenatal support for mothers as a significant factor, recognizing its impact on early childhood development.ASD and speech impairments significantly affect children's education and social integration, particularly in underserved communities.While 5-10% of school-aged children experience speech impairments, other challenges arise for children with ASD when these conditions co-occur (Health Resources and Services Administration [HRSA], 2024).Despite their prevalence, disparities in access to diagnostic services are poorly understood, especially in disadvantaged California regions.These challenges make it even more important to ensure children with ASD and speech impairments get the right support, especially in areas where resources are limited.This is why this research asks: What socioeconomic, racial, and geographic factors influence autism and speech impairment diagnosis rates among children aged 0-22 across
