Background: The literature on influences of community versus congregated settings raises questions about how social inclusion can be optimised for people with intellectual disability. This study examines social contacts for older people with intellectual disability in Ireland, examining differences in social connection for adults with intellectual disability and other adults. Materials & Methods: Data were drawn from the IDS-TILDA study in Ireland. A nationally representative sample (n = 753) included adults aged 40 years and older, with additional comparison with general population participants. Predictors of social contacts were explored. Results: Residence, level of intellectual disability and age were significant factors determining social contact. People in institutional residences, older respondents and those with severe/profound intellectual disability had the lowest levels of contact; older adults with intellectual disability had much lower rates than general population counterparts. Conclusions: Community-dwelling people with intellectual disability have greater social contact than those living in institutions, but levels are below those for other adults in Ireland.
