A landmark synthesis of data covering more than 21 million children across six continents suggests that roughly one in every 130 children worldwide lives with autism spectrum disorder — a figure that likely understates the true scale, particularly in nations where screening is sparse and specialists are few. The disparity between wealthy and lower-income countries does not reflect a difference in how many children are affected, but rather a difference in how many are seen. What is unmeasured goes unmet, and the children who fall outside the count often spend their most formative years without

Global study of 21M children reveals autism support gaps in low- and middle-income nations
Children with undiagnosed or late-diagnosed autism miss early access to critical support services including speech therapy, behavioral support, and educational planning during key developmental periods.

Widening healthcare disparity between high-income and low/middle-income nations; potential shift in global health priorities toward neurodevelopmental disorders; increased pressure on developing nations to establish screening infrastructure, creating dependency on high-income country expertise and resources.
Similar to global health disparities in mental health services (1990s-2000s) where diagnostic gaps in developing nations were later addressed through WHO initiatives and international funding mechanisms.

Global study estimates 0.77% of children have autism, revealing significant diagnostic gaps in low- and middle-income nations, indicating underinvestment in screening, specialist services, and early intervention infrastructure.

Families in low- and middle-income countries face delayed diagnoses and limited access to support services, increasing long-term healthcare costs and educational challenges. Households in high-income countries benefit from better screening and services but face rising demand on public health systems.
Governments will likely increase healthcare budgets for autism screening programs, specialist training, and early intervention services. Policy responses may include mandatory screening protocols, investment in diagnostic infrastructure in underserved regions, and education system reforms to support neurodivergent children.
