The number of immigrants to the State in the year to April 2017 is estimated to have increased by 2.8% from 82,300 to 84,600, while the number of emigrants declined over the same period, from 66,200 to 64,800. These combined changes have resulted in net inward migration for Ireland in 2017 (+19,800), the highest level of net inward migration since 2008. See table 1.

Irish nationals continue to experience net outward migration, although at a much lower level than in the previous year, falling from -8,800 to -3,400, while net inward migration among non-Irish nationals decreased from 25,000 to 23,200.  See table 2.

The number of births in the period was 63,900 while the number of deaths was 30,800, resulting in a natural increase of the population of 33,100.  See table 1.

The combined effect of natural increase and positive net migration resulted in an overall increase in the population of 52,900 bringing the population estimate to 4.79 million in April 2017.  See table 1.


This release includes revisions to the Population and Migration Estimates for the years 2012 - 2016 inclusive. The estimates for these years have been revised in line with the Census 2016 usually resident population, which became available in April of this year. As a result of these revisions the usually resident population estimate for 2016 has been revised upwards by 65,900.

See background notes for more information.


Other main features of the 2017 figures are: 

  • Of the 84,600 people who immigrated to Ireland in the year to April 2017, some 27,400 (32.4%) were estimated to be Irish nationals. See table 2.
  • Of the 64,800 people who emigrated from Ireland in the year to April 2017, 30,800 (47.5%) are estimated to be Irish nationals. This represents a decrease of 6,300 (-17.0%) on the year to April 2016 when 37,100 Irish nationals left to live abroad. See table 2.
  • Net outward migration of Irish nationals in 2017 was -3,400, which is a descrease of 88.5% on 2012 when net outward migration of Irish nationals peaked at -29,600. See table 2.
  • Non Irish-nationals from outside the EU continued to display strong migration flows, accounting for 29,400 (34.8%) of total immigrants and 13,700 (21.1%) of total emigrants. This resulted in estimated net inward migration among non-Irish nationals from outside the EU of 15,700.  See table 2.
  • In April 2017, 42,100 (55.5%) of immigrants aged 15+ were in employment. See table 6.
