Irish in Scotland
Considering the Dal Riada kingdoms and the Irishisation of Scotland in the early Middle Ages, it is difficult to determine
how many Scots have genetic Irish ancestry or how many were Picts who adopted Irish lifestyles, although the general
consensus is that both happened as Pictish culture vanished by the 11th century. In 2001, around 55,000 people in
Scotland had been born in Ireland, while people of Irish heritage make up about 20% of the population.
