The aim of this study is to examine the impact of child race-ethnicity and neighborhood characteristics on age of treatment receipt among children with autism spectrum disorder. Here, we included 1309 children diagnosed with autism spectrum disorder in the National Survey of Children’s Health, 2011–2012. Controlling for key covariates, we used a weighted generalized logit model to analyze differences in age of treatment receipt (<2？years, 2？years, 3？years, and ？4？years). Compared to non-Hispanic White children, the relative probability (odds) of entering treatment at 3？years and ？4？years rather than <2？years was 326% and 367% higher, respectively, for non-Hispanic Black children. Compared to children whose parents perceived their neighborhood to be cohesive, the relative probability of entering treatment at 2？years and 3？years rather than <2？years was 59% and 61% lower, respectively, for children whose parents did not. Significant racial-ethnic and neighborhood inequities exist in age of treatment receipt, suggesting a need for research that explores the underlying causal mechanisms of inequities
