A 2022 study across 16 diverse sites revealed significant variations in Autism Spectrum Disorder (ASD) identification practices and prevalence rates. California showed the highest prevalence, potentially due to early detection initiatives. Disparities existed across racial and ethnic groups, with higher rates among non-White children, possibly reflecting improved access to services. However, socioeconomic factors showed less consistent correlation with ASD prevalence. While early identification has improved, the male-to-female ratio remains skewed, and the study suggests a need for increased access to diagnostic services, particularly for underserved communities. The impact of COVID-19 on ASD identification appeared minimal.
