Study conducted by the Prince Mohammed Bin Salman Autism Program and Arthur D. Little drawing from global and regional benchmarks
Autism prevalence in KSA estimated at 1.70%- 1.75%, compared to previously published 0.6%
The Prince Mohammed Bin Salman Autism Program, Ministry of Defense, of the Kingdom of Saudi Arabia, in collaboration with global consultancy Arthur D. Little (ADL), has published a comprehensive study examining the estimated prevalence of autism spectrum disorder (ASD) among children in the Kingdom. The peer-reviewed journal paper published in the Saudi Medical Journal suggests that prevalence may range between 1.70 percent and 1.75 percent – significantly higher than the currently cited figure of 0.6 percent.
Titled Estimating Autism Prevalence Among Children in KSA: A Comprehensive Multisource Benchmarking Approach, the white paper applies a structured analysis of international and regional data to provide a more realistic estimate of autism spectrum disorder (ASD) prevalence in the Kingdom. It integrates recent peer-reviewed Saudi research, including the largest national meta-analysis to date, and compares findings against global benchmarks from countries with mature healthcare systems and advanced ASD monitoring infrastructure. By adjusting for local factors such as population structure, healthcare access, and diagnostic practices, the study offers a calibrated view of autism prevalence that reflects the unique context of Saudi Arabia. Its goal is to support more accurate policy planning, promote early detection, and help build a more inclusive, equitable framework for autism care aligned with Vision 2030.
“Addressing autism through a national lens requires a clear understanding of its prevalence across populations. This study provides valuable baseline estimates and highlights the need for stronger, locally generated data to inform care and policy. The work of our colleagues at the Prince Mohammed Bin Salman Autism Center reflects a commendable effort to consolidate available evidence and bring greater visibility to an important public health issue in the Kingdom.” said Dr. Waleed Alhazzani, director of the Center of Excellence for Health Science Research at the Ministry of Defense, who was not among the study’s authors
The analysis draws on data from countries with well-established autism surveillance systems – including the United Kingdom, United States, Denmark, South Korea, and Italy – each offering unique insights into how screening intensity, diagnostic thresholds, and health system maturity influence reported prevalence. To ensure regional relevance, the study also incorporates data from the UAE, Qatar, and Jordan. These countries share cultural and demographic similarities with Saudi Arabia and face comparable challenges in terms of underreporting and service accessibility. By adjusting for structural and systemic differences across these markets, the study delivers a tailored estimate grounded in international best practices yet reflective of the Saudi healthcare and social landscape.
“Reliable data is essential for delivering real impact,” said Dr. Patrick Linnenbank, Partner, healthcare practice at Arthur D. Little Middle East. “This study contributes to a clearer understanding of autism prevalence in the Kingdom and offers a constructive foundation for enhancing screening, diagnosis, and support.”
The report encourages decision-makers to prioritise continued investment in early detection efforts, expand the reach of national screening programs, and address geographic disparities that limit access to diagnosis and care in areas outside major cities. It also underscores the role of public awareness and community engagement in reducing the social stigma often associated with autism diagnoses. Together, these steps are critical to ensuring that more children receive timely support – and that families, educators, and healthcare professionals are equipped to respond with confidence and compassion.
