"No Irish need apply" are the discriminatory words which once accompanied job advertisements in some parts of Britain and the United States of America.
The same phrase is now the title of a new exhibition in Dublin's immigration museum, EPIC, which examines what life has been like for Irish people who emigrated to England in the past 200 years.
There are around 500,000 Irish-born people living in England today, and thousands of Irish have been emigrating to the UK for centuries.
Researchers used "vital" records, such as the census, and birth, marriages, and death certificates, to track infant mortality and life expectancy to measure living standards.
The number of Irish-born people in England peaked at around 900,000 in the 1970s, due to mass emigration in the 1950s.
