Net outward migration among Irish nationals grows

Figure 1 PME - Migration

Total emigration from Ireland in the year to April 2013 is estimated to have reached 89,000, an increase of 2.2 per cent on the 87,100 recorded in the previous year.  The number of immigrants also increased over the same 12 month period from 52,700 to 55,900 (or 6.0 per cent). 

This has resulted in total net outward migration remaining broadly constant with the previous twelve month period (33,100 compared with 34,400 respectively). However, among Irish nationals, net outward migration is estimated to have increased significantly, rising from 25,900 to 35,200, while that of non-Irish nationals is estimated to have changed from net outward (-8,400) to net inward (2,100). (Table 2)

The number of births in the period was 70,500 while the number of deaths was 29,700, resulting in a natural increase of the population of 40,800, a fall of 4,100 on the previous year's figure of 44,900.

The combined effect of natural increase and negative net migration resulted in an overall small increase in the population of 7,700 bringing the population estimate to 4.59 million in April 2013. (Table 1)

Other main features of the 2013 figures are: 

  • Of the 89,000 people who emigrated in the year to April 2013, Irish nationals were the largest group accounting for 50,900 or 57.2 per cent. 
  • The estimated number of people aged 14 years and under now exceeds a million (1,007,700) for the first time since 1987.   
  • The population increase of 0.2 per cent was unevenly distributed across the regions, with the South-East showing the strongest growth at 0.9 per cent and the Mid-West showing the largest decrease of 0.6 per cent.
  • 24.6 per cent (21,900) of emigrants went to the UK while 17.3 per cent (15,400) went to Australia. (Table 3)

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 population classified by age and sex for the year 2011 is taken from the Census of Population.

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.

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 2012 figure was the number of males and females in each region by single year of age and nationality as established by the 2011 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 2012 figures. The end result of this overall process provided the population estimate for April 2012 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.  Births by nationality are estimated using the distribution of the nationality of babies as recorded in the 2011 census, while deaths by nationality are also estimated based on recent census results on the nationality distribution of the population by single year of age.

Migration by origin/destination

This release provides for the first time estimates of migration to and from Australia and Canada as individual countries of origin/destination. This is part of the ongoing work by the CSO to improve data in this area, which in recent years has included new data on the nationality of emigrants (Table 2) and an estimate of the total population by nationality (Table 7).

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.
