Population of Ireland

Ireland Country Population

In the late 1840s, the potato crops were hit by repeated catastrophic destruction, and nearly one million people died of starvation. At the same time, over 1.5 million emigrated, mostly to the United States. Later, Britain became the most important target of emigration. Between 1841 and 1920, a total of 4.5 million Irish emigrated, and the emigration is still relatively large.

The population declined until the 1960s, but has subsequently grown, but with some periods of decline due to high emigration. Natural growth (born ÷ dead) is very high in the European context. In 2016, the birth rate was 13.7 ‰ and mortality 6.5 ‰ (World Bank). Due to continued emigration, the annual real growth in population (2016) is 0.86%.

Life expectancy is 82.6 years for women and 78 years for men.

The population is of Celtic origin with strong elements of Scandinavians and Anglo-Saxons.

Within the country there has been a migration of people from the inner regions and out to the coast, where most cities are located. The largest cities are the capital Dublin and Cork.


Official languages ​​are Irish and English. English dominates as both oral and written language. The vast majority of Irish speakers are bilingual with Irish as a second language. The Irish-speaking districts (Gaeltacht) are located on the islands and along the coast to the west.
