Researchers used “vital” records, such as birth, marriages, and death certificates, to track infant mortality and life expectancy to measure living standards.
Professor Neil Cummins analysed some of these records which shine a light on what life was like for Irish people in England during the past 200 years.
But why did the Irish have such a hard time in England?
Cummins said the “flow” of migration from Ireland to England was dominated by the exodus of lower educated, lower class Irish people.
“There is quite strong evidence, anecdotal and now statistical from colleagues in LSE that there was specific discrimination against Irish people in the labour force.
“There does seem to be an Irish penalty in England.”
But Cummins, who has lived in England himself for about two decades, says life is much better for Irish people in England now.
“London, I think for me, is wildly different than it was for the Irish 50 years ago. It is a multicultural place where being Irish confers many advantages.”
