Description: The 310-mile Irish border divides the Republic of Ireland and Northern Ireland. These two states have an open-borders “Common Travel Area” which includes the United Kingdom, Ireland, the Isle of Man and the Channel Islands. The Republic of Ireland and Northern Ireland are part of the European Single Market, which attempts to ensure free movement of goods, capital, services and labor within the European Union. After the Brexit vote, the future status of the border has been disputed and remains unclear. The number of immigrants in Ireland in 2018 is estimated to have increased by 6.7%. The net inward migration for Ireland in 2018 is the highest level since 2008. Net inward migration among non-Irish nationals remained strong, increasing from 23,200 in 2017 to 33,900 in 2018. Non-Irish nationals from outside the EU continued to display strong migration flows, accounting for 30,900 (34.2%) of total immigrants.
