Demographics of Ireland: about 5 million people, with a strong immigrant presence
A small country with a population growing through immigration. Dublin concentrates more than a quarter of the inhabitants and the largest share of immigrant communities.
Ireland has about 5 million inhabitants, making it one of the least populous countries in the European Union. Dublin's metropolitan area gathers about 1.5 million people, and it is where most immigrants settle. Other important cities for foreigners are Cork, Galway, Limerick, and Waterford.
Immigration carries enormous weight in present-day society. The largest foreign communities come from Poland, the United Kingdom, India, Romania, Lithuania, and the Philippines. There is also a growing presence of Latin Americans, Ukrainians under temporary protection since 2022, and Nigerians. About 20% of the resident population was born outside the country.
English is the language of daily life and business, taught in all schools. Irish (Gaeilge) is co-official, taught compulsorily, and spoken in areas called Gaeltacht (west of the country), but rarely heard in urban conversations. Polish, Romanian, Hindi, Spanish, and Portuguese appear in specific neighborhoods and shops in Dublin and Cork.
