The disadvantages experienced by adult persons with disabilities are well documented. However, limited evidence is available on the extent of differences in comparison with the non- disabled population. In this study, selected indicators of social status and mental wellbeing derived from past research, were used with national samples of adult persons in Ireland with a disability (n = 440) and without a disability (n = 880) recruited through household quota sampling. In addition, comparisons were drawn with equivalent data derived from a contemporaneous national census. Although many of the differences were statistically significant, the effect sizes were mostly medium to low. Moreover, when the inter-relationships among the various indicators was taken into account using Discriminant Analysis, persons with disabilities were less likely to be employed; they reported lower levels of social engagement and had poorer emotional wellbeing. They were also older, more likely to be single and have no children. The study illustrates the potential of using comparative data to monitor the impact of national actions taken to reduce the inequalities experienced by persons with disability as well as highlighting the arenas into which professional supports need to be focused.
