Across the European Union, an increase in life expectancy is commonly reported with women outliving men (Eurostat, 2019). In the Republic of Ireland, the mean age of death in the general population in 2001 was 73 years and by 2016, this had increased to 76 years, although for women the mean age of death was 79 years and for males, 74 years (CSO, personal communication). However, increases in life expectancy were not uniform across the population. Lower life expectancy was found among persons living in more socially deprived areas, in urban settings, in rented accommodation provided by local authorities, and for people who were single and less educated (CSO, 2010).Internationally, for people with intellectual disability, their mean age of death is notably lower than for the general population. A systematic review of 27 studies concluded that a gap of around 20 years exists with greater inequality for women with intellectual disability than for men (O'Leary et al., 2018). It is unclear the extent to which the gap has reduced in recent years due mainly to a dearth of longitudinal studies. Nevertheless a study of deaths of people with intellectual disability in one English city over a 33 year period up to 2012 suggested that the gap persisted although there were increases in the life expectancy of people with intellectual disability (Emerson et al., 2014).Two previous studies have reported deaths of Irish people with intellectual disability. In the period 1996 to 2001, the mean age of
