Demographics of the Republic of Ireland


The Republic of Ireland had a population of 4,761,865 at the 2016 census.

Demographic history

The island of Ireland, throughout most of its history, had a small population, comparable to that of other regions of similar area in Europe. In the 18th and early 19th centuries, Ireland experienced a major population boom as a result of the Agricultural and Industrial Revolutions. In the 50-year period 1790-1840, the population of the island doubled from 4 million to 8 million. At its peak, Ireland's population density was similar to that of England and continental Europe.
This changed dramatically with the Great Famine of the mid-19th century, which led to mass starvation and consequent mass emigration. In the area covering the present day Republic of Ireland, the population reached about 6.5 million in the mid 1840s. Ten years later it was down to 5 million. The population continued a slow decline well into the 20th century, with the Republic recording a low of 2.8 million in the 1961 census.
During the 1960s, the population started to grow once more, although slowly as emigration was still common. In the 1990s the country entered a period of rapid economic growth as a result of the Celtic Tiger Irish economic boom. The Republic started to receive Immigration from that had never previously happened. Many former Irish emigrants returned home, and the Republic of Ireland became an attractive destination for immigrants, from other member states EU such as Central Europe, but also from outside the EU such as Africa, Asia and elsewhere. With the 2008 onset of the Irish economic and banking crisis, the state's economy suffered, and the Republic of Ireland has once again been experiencing net emigration of its citizens, but immigration remains high.
In November 2013, Eurostat reported that the republic had the largest net emigration rate of any member state, at 7.6 emigrants per 1,000 population. However, it has the youngest population of any European Union member state and its population size is predicted to grow for many decades, in contrast with the declining population predicted for most European countries. A report published in 2008 predicted that the population would reach 6.7 million by 2060. The Republic has also been experiencing a baby boom, with increasing birth rates and overall fertility rates. Despite this, the total fertility rate is still below replacement depending on when the measurement is taken. The Irish fertility rate is still the highest of any European country. This increase is significantly fuelled by non-Irish immigration – in 2009, a quarter of all children born in the Republic were born to mothers who had immigrated from other countries.

Ethnic groups and immigration

and language forms an important part of the Irish national identity.
The Irish Travellers are an indigenous minority ethnic group, formally recognised by the Irish State since 1 March 2017.
In 2008, Ireland had the highest birth rate, lowest death rate and highest net-migration rate in the entire European Union – and the largest population growth rate in the 27-member bloc as a result.
Ireland contains several immigrant communities, especially in Dublin. The most common foreign nationalities include Polish, British, Lithuanian and Latvian
There is only genetic evidence for pre-Celtic migration into Ireland. The Irish people may therefore be described as strongly influenced by Celtic language and traditions.

Total fertility rate from 1850 to 1899

The total fertility rate is the number of children born per woman. It is based on fairly good data for the entire period. Sources: Our World In Data and Gapminder Foundation.
