Ireland's population estimated to be just over five million in April 2021

Ireland's population was estimated to be 5.01 million in April 2021, which is the first time the population has risen above five million since the 1851 census, when the comparable population was 5.11 million. See table 1.1 and figure 1.1. The total population on the island of Ireland in 1851 was 6.6 million.

Population growth of 34,000 (+0.7%) in the year to April 2021, the smallest population increase since 2014

The combination of natural increase and positive net migration gave population growth of 34,000 (+0.7%) in the year to April 2021. This was smaller than the rise of 55,900 (1.1%) in the year to April 2020. This is the smallest population gain since 2014 when the population increased by 30,800. See figure 1.2 and table 1.2.

There were 55,500 births and 32,700 deaths in the year to April, giving a natural increase (births less deaths) in the population of 22,800. This is the lowest level of natural increase recorded since the 2000 population estimates. See figure 1.2 and table 1.2.

The number of immigrants to the State in the year to April 2021 is estimated to have decreased by 23.7% to 65,200 from 85,400 in the year to April 2020. The number of emigrants also decreased over the same period to 54,000 from 56,500. These combined flows gave positive net migration, (i.e., more people arrived than left), of 11,200 in the year to April 2021, compared with 28,900 in the previous year, a decline of 61.2%. See figure 1.3 and table 1.2.

Table 1.2 Components of the annual population change, 1987 - 2021

More Irish nationals returning to live in Ireland

There were 30,200 immigrants and 22,800 emigrants who were Irish nationals in the year to April 2021. Therefore, the number of Irish nationals who arrived here to live was just over 7,300 higher than the number who left to live abroad. In contrast, inflows of non-EU nationals (rest of world) declined to 14,100 in the year to April 2021, from 30,400 the previous year, a decrease of 16,300 (-53.6%). See figure 1.4 and table 1.3.

Table 1.6 Estimated Migration (aged 15 and over) classified by Sex and Education Attainment, 2016 - 2021

In April 2021, more than 1 in 7 people living in Ireland were aged 65 or older

There were 742,300 people living in Ireland aged 65 and over in April 2021. Those aged 65 and over are the only group to gain population share between 2016 and 2021, increasing from 13.3% to 14.8% of the total, this equates to a volume increase of 112,500. The traditional working age population i.e. those aged 15-64 have grown by around 170,000 persons since 2016, but have seen their population share decline slightly from 65.5% to 65.3%. The population aged 0-14 has seen its population share decline by 1.3 percentage points (10,000 persons) since 2016. See figure 1.8 and PXStat table of the population classified by single year of age, PEA11.
