This increase is significantly fuelled by non-Irish immigration – in 2009, a quarter of all children born in the Republic were born to mothers who had immigrated from other countries.
Zvyšování populace je ale poháněno spíš imigrací než porodností - v roce 2009 se čtvrtina všech dětí narodila matkám, které do Irska imigrovali odjinud.
