About the publication:
The report provides comprehensive analysis of autism prevalence by:
- Gender
- School year
- Health and Social Care (HSC) Trust areas
- Area deprivation (Multiple Deprivation Measure deciles)
- Urban/rural split
The information is derived from the 'Northern Ireland School Census' collected by the Department of Education (NI). Children with autism are identified using the ICD10 diagnosis coding, which includes those diagnosed with Asperger Syndrome.
It's important to note that due to changes in how autism data is collected (moving from the special educational needs register to the electronic Medical register), figures from 2018/19 and earlier are not directly comparable with current years.
