Abstract
Decisions about ethnic groups studied in health research shape recommendations. If a group is not included in research, its ability to call for policy change is limited. Despite health inequalities for the Irish in Britain in the 20th century, recent research on health is likely to combine the White Irish with White British, whereas Irish people of colour are not mentioned at all. This paper aims to understand why the interest in this group has declined. A state-of-the-art literature review of 140 papers on Irish health in Britain from 2001 to 2023 was conducted. Findings show the Irish are still disadvantaged in mortality, mental health and suicide, with important socioeconomic status and gender disparities. The shifting way the Irish are constructed over time is critically examined, paying attention to historical depictions and postcolonial identities. Sociological theories of migration are challenged by the Irish because this migrant group does not conform to theoretical assumptions. The Irish may have dropped from the agenda because of incorrect assumptions about assimilation and the relationship between Ireland and the UK. Given that the health outcomes of the Irish in Britain differ from those of the White British population, they should be recognised in health research as a distinct group.
