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.
  • In the year to April 2017 18,700 immigrants arrived to live in Ireland from the UK, 12,100 emigrants left Ireland to live in the UK. See table 3.
  • In April 2017, 1,350,000 persons (28.2%) of the usually resident population lived in Dublin.  See table 8.

Background Notes

Coverage

The reference period for the population estimates is mid-April of the years shown, while the migration flows are in respect of the twelve months to mid-April of the corresponding years, as are the births and deaths. The usually resident population classified by age and sex for the years 2011 and 2016 are taken from the Census of Population held in those years. The population and migration estimates for the 2012 - 2016 period have been revised in the light of the 2016 Census results.

Usual residence population concept

For the purpose of this release the population concept of usual residence has been used, i.e. all persons usually resident and present in the State on census night plus absent persons who are usually resident in Ireland but are temporarily away from home and outside the State on census night. All persons are classified according to their region of usual residence.

Migration Definitions

Immigration - means the action by which a person establishes his or her usual residence in the State for a period that is, or is expected to be, of at least 12 months, having previously been usually resident in another Member State or a third country.

Emigration - means the action by which a person, having previously been usually resident in the State, ceases to have his or her usual residence in the State for a period that is, or is expected to be, of at least 12 months.

Source of Migration data

The principal source of information for the estimation of the gross annual migration flows is the Quarterly National Household Survey (QNHS), which also provides the basis for the classification of the flows by sex, age group, origin/destination and nationality.

The migration estimates are compiled with reference to movements in other migration indicators such as the number of Personal Public Service (PPS) numbers allocated to non-Irish nationals and the number of visas issued to Irish nationals to a number of the destinations including Australia, US and Canada.  In addition, data on National Insurance numbers (equivalent to PPS numbers) issued to Irish nationals in the UK is referenced.

The release also provides estimates of immigration and emigration by educational attainment (Table 5) and principal economic status (Table 6), based on responses in the QNHS. The principal economic status question refers to persons aged 15 years or over and is a self-perception question, i.e. people are classified according to how they perceive their situation.

As with all breakdowns of migration (by age, nationality, origin and destination), the breakdown by educational attainment and principal economic status should be considered broadly indicative given the relatively small sample sizes associated with these flows. In addition, as a person's principal economic status can change over the course of a year (and to a lesser extent their educational attainment), for immigrants these two tables refer to their status in the quarter prior to the April of the year in question, while for emigrants it is their status in the period prior to departure.

Calculation of annual population estimates

The annual population estimates for mid-April in this release were calculated by trending forwards the previous Census of Population data. For example, the base population data for estimating the April 2017 figure was the number of males and females in each region by single year of age and nationality as established by the 2016 Census. From this base, each person was aged by one year, births for the period were added and deaths were subtracted. The estimated number of immigrants was then added and the number of emigrants was subtracted. Allowance was also made for estimated inter-regional migration in arriving at the final 2017 figures.

The end result of this overall process provided the population estimate for April 2017 which in turn will provide the base population for the subsequent year and so on. The population estimates are subject to revision once the definitive results of the next census become available.

The population by nationality estimates are made possible by trending forwards the previous Census of Population and incorporating gross migration flows by nationality based on responses in the QNHS. Allowance is also made for the non-Irish nationals who acquire citizenship certificates over the period in question. The number of births by nationality is estimated using the distribution of the nationality of births as recorded in the 2016 census, while deaths by nationality are also estimated based on recent census results using the nationality distribution of the population by five year age groups.

Revision of inter-censal population estimates

The change in the population between successive Censuses reflects not only the effect of births and deaths but also all movements of persons internally between regions and into and out of the State between both dates.

The population estimate for April 2016 was 4,673,700, 65,900 persons fewer than the 2016 Census usually resident population of 4,739,600. However, it should be borne in mind that the estimated gross migration flows over this inter-censal period are estimated at almost 720,000.

Natural Increase

The General Registration Office (GRO) supplies registered data for births and deaths and these are typically added to the population file quarterly in arrears (N+1). As part of the revisions process births and deaths were assigned to the appropriate registration period, as a result of this the natural increase for the 2012 - 2016 period was revised downwards by 700 persons when taken into account.

International Migration

After the adjustment to births and deaths, the residual provides a measure of the overall net migration (i.e. the difference between inward and outward flows) for the five year inter-censal period.

A detailed analysis of the Personal Public Service (PPS) numbers allocated to non-Irish nationals in a given year which still had either employment (P35) or social welfare activity the following year, combined with information on the number of work permits issued to Irish nationals in a given year, suggests that immigration was underestimated and emigration was overestimated over the period. Therefore inward and outward flows have been adjusted accordingly. Immigration has been revised upwards by 26,900 persons while emigration has been revised downwards by 39,700 persons.

Revisions to the immigration data also took account of the 2016 Census results on one year inflows and the recorded year of arrival of immigrants.

Revisions to emigration have taken account of work permits issued to Irish nationals to a number of destinations including Australia, US, Canada and New Zealand. In addition, data on National Insurance numbers (equivalent to PPS numbers) issued to Irish nationals in the UK were also incorporated in the revisions.

Internal migration

By examining a person's usual residence at the time of a census and one year previously it is possible to determine inter-regional migration patterns. Following each Census a new internal migration matrix is produced and used to measure inter-censal internal migration. Internal migration for the year to April 2017 has been updated to take account of the Census 2016 results.

Nationality

All persons with Irish nationality or citizenship are classified under the category "Irish" in table 9 (Estimated population classified by sex and nationality).

The Irish Naturalization and Immigration Service provide annual data for persons who acquire Irish citizenship. While some 94,000 citizenship certificates were issued for the period 2012 - 2016 inclusive, when usual residence and calendar effects were accounted for, some 93,000 of these citizenship/nationality acquisitions were relevant for the purpose of this release.

For the years 2012 - 2016 citizenships were allocated to the year in which the citizenship certificate was issued. The availability of the citizenship data for year N is N+1 and so estimates for 2017 and subsequent years will be achieved by trending forward the rates noted for the most recent year available.
