Latest trend of Autism in India is 1 in 68 children are Autistic. The methodology had clearly stated and admitted undiagnosed cases in rural areas, among tribal children, and at certain community levels. Even government-level recordings also have certain exclusions due to non-cooperation of parents in disclosing information on their child.
Regarding the intellectual disability scenario in India, its estimate is only approximate due to its data in a population of more than 1.4 billion. Still, the general survey had agreed on the number being approximately 20 million, including autism, which is more than 3 million.
Government Focus & Data Gaps
Apathy of government towards these children due to their minority status compared with UDISE data for general students of 24.80 crore (248 million) in the year 2024-25. The number of autistic children is around 3 million, and the total number of autistic and intellectually disabled people is 30 million.
The latest survey, conducted by NSSO in the year 2018-19, shows that 2.2% of the population are with intellectual disability (2.3% in rural, 2.0% in urban). The data says, among persons with disabilities aged 3-35 years, 62.9% had ever enrolled in an ordinary (mainstream) school, and 4.1% in special schools or received specialized therapy.
The sad part of the survey is that it does not separately enumerate autism/autism spectrum disorder (ASD). That category is not explicitly listed in the standard NSS disability types. Latest data shows 4 million children are suffering from Autism Spectrum Disorder (ASD). Unfortunately, NSSO does not take special studies on autism.
Note: Countries such as the USA, England, South Korea, Australia, and many European countries do have their detailed surveys and have complete data of ASD and intellectual disability.
