2947. Deputy Michael Collins asked the Minister for Children, Disability and Equality the percentage of the total number of adults with an intellectual disability in the State that the HRB/NASS annual bulletin represents, by reference to the total number of adults with an intellectual disability in the country; and if she will make a statement on the matter.

The National Ability Supports System (NASS) does not include data on all adults with an intellectual disability (ID). NASS data includes data pertaining to adults with an ID who are in receipt of or who are identified as requiring HSE funded specialised disability services. These are generally people with more complex levels of disability or overlapping impairments who are known to disability service providers. Mainstream services such as primary care cater for people with less complex needs, such as many of the adults with borderline or mild intellectual disability. Data collection on mainstream supports and services are not under the remit of NASS.

For 2025, HRB NASS recorded 20,933 adults with either a primary (n=19,490) or secondary (1,443) diagnosis of intellectual disability. The Census figures on intellectual disability (data.cso.ie/table/F4006), includes all adults self-reporting an ID, and this cohort will include adults receiving services outside of the HSE disability service budget. The adults with an ID reported on NASS in 2025 represent two thirds (66%) of the 31,499 adults identified in Census 2022 with an intellectual disability ’to a greater extent’, and 20% of the 103,891 adults with ID either ‘to some extent’, or ‘to a greater extent’.
