The Polish minority in Ireland numbered approximately 122,515 (2.57% of the population) according to 2016 census figures.
After Poland joined the European Union in May 2004, Ireland was one of three existing EU members to open its borders to Polish workers (the others being the United Kingdom and Sweden). Ireland quickly became a key destination for Poles wishing to work outside the country; in 2004 a website advertising Irish jobs in Polish received over 170,000 hits in its first day.
n the period immediately following the 2008 economic downturn, the number of Polish people in Ireland declined, with some reports suggesting that 30,000 were leaving Ireland per year, and the Central Statistics Office reporting a decrease in the number of Polish people applying for PPS numbers.
Polish people living in Ireland can vote in Polish elections. On Election Day there are special ballot stations provided in Belfast, Cork, and Limerick as well as in the country's embassy in Dublin. Consequently, Polish political parties campaign in Ireland for electoral support.
