Historical chart and dataset showing Ireland immigration statistics by year from 1960 to 2015.

Between 1820 and 1957, over 4.6 million people emigrated from the island of Ireland to the United States. The period with the highest levels of migration came between 1845 and 1855 , as the Great Famine devastated Ireland's population, causing the deaths of roughly one million people and leading to the migration of one million more, most of which was to the United States. The period with the lowest levels of migration came in the 1930s and 40s, as the Great Depression and Second World War created an environment where migration to the US was difficult or impractical.

Ireland net migration for 2024 was 39,059, a 10.97% decline from 2023.

Ireland IE: International Migrant Stock: % of Population data was reported at 15.917 % in 2015. This records an increase from the previous number of 15.822 % for 2010. Ireland IE: International Migrant Stock: % of Population data is updated yearly, averaging 11.569 % from Dec 1990 (Median) to 2015, with 6 observations. The data reached an all-time high of 15.917 % in 2015 and a record low of 6.224 % in 1995. Ireland IE: International Migrant Stock: % of Population data remains active status in CEIC and is reported by World Bank. The data is categorized under Global Database’s Ireland – Table IE.World Bank.WDI: Population and Urbanization Statistics. International migrant stock is the number of people born in a country other than that in which they live. It also includes refugees. The data used to estimate the international migrant stock at a particular time are obtained mainly from population censuses. The estimates are derived from the data on foreign-born population--people who have residence in one country but were born in another country. When data on the foreign-born population are not available, data on foreign population--that is, people who are citizens of a country other than the country in which they reside--are used as estimates. After the breakup of the Soviet Union in 1991 people living in one of the newly independent countries who were born in another were classified as international migrants. Estimates of migrant stock in the newly independent states from 1990 on are based on the 1989 census of the Soviet Union. For countries with information on the international migrant stock for at least two points in time, interpolation or extrapolation was used to estimate the international migrant stock on July 1 of the reference years. For countries with only one observation, estimates for the reference years were derived using rates of change in the migrant stock in the years preceding or following the single observation available. A model was used to estimate migrants for countries that had no data.; ; United Nations Population Division, Trends in Total Migrant Stock: 2008 Revision.; Weighted average;

This database covers immigration-related demographic data for 7 Western European countries (Austria, Belgium, Ireland, Netherlands, Spain, Switzerland, and United Kingdom) between 1990 and 2009. A number of indicators are included to cover the following aspects: (1) a general overview about the immigrant population in the selected countries (2) information about numbers of immigrants entering and settling in the selected countries (3) information about the backgrounds of immigrants, such as countries of origin, religious backgrounds, gender and education. The data were collected as part of the FP7-funded project Support and Opposition to Migration (http://www.som-project.eu/)

As part of its annual publication of Population Estimates, NISRA produces official migration estimates for Northern Ireland which reflect the estimated flows of people to and from Northern Ireland from 1 July to 30 June each year. These migration estimates are primarily based on changes observed in the Medical Card Register and detail the inflows and outflows by age and gender for those travelling to/from the rest of the UK and areas outside the UK.

Luxembourg is the European Union member state with the greatest share of its population being citizens of other EU member states, with almost 38 percent of people in the country coming from elsewhere in the EU. The small western European state has become a hub for immigration due to its status as one of the administrative centres of the EU (including being the location of the European Court of Justice and European Investment Bank), a key location for financial services companies, and due to its close proximity population centres of other member states such as France, Germany, and Belgium. Other countries with a large share of their population coming from elsewhere in the EU include Austria, Belgium, and Ireland, three countries which have seen increased intra-EU migration in recent years due to strong work opportunities in international organisations (Belgium and Austria) and multinational companies (Ireland).

This graph shows the distribution of nationalities among documented immigrants who arrived in the United States between 1820 and 1870. As we can see, over seven million people arrived in the US in this 50 year period, with the majority coming from Ireland, Germany and Britain. The largest groups, by far, were Irish and German, who together made up roughly two thirds of all immigrants to the US during this time. The reasons for this were because of the Irish Potato famine from 1845 to 1849, which resulted in the death or emigration of twenty to twenty five percent of the total Irish population, and a number of internal factors in Germany such as economic migration for farmers affected by industrialization, political/religious asylum, and in order to avoid conscription. One noteworthy exclusion from the information is of those transported to US as slaves, whose information was not recorded in this statistic (although the slave trade was abolished in 1808, the practice continued in the decades that followed).
