Irish Migration To Great Britain - 19th Century Onwards

19th Century Onwards

The most significant exodus followed the worst of a series of potato crop failures in the 1840s - the Great Famine. It is estimated that more than one million people died, and almost the same again emigrated. A further wave of emigration to England also took place between the 1930s and 1960s by Irish escaping poor economic conditions following the establishment of the Irish Free State. This was furthered by the severe labour shortage in Britain during the mid-20th century, which depended largely on Irish immigrants to work in the areas of construction and domestic labour. The extent of the Irish contribution to Britain's construction industry in the 20th century may be gauged from Sir William MacAlpine's 1998 assertion that the contribution of the Irish to the success of his industry had been 'immeasurable'.

Ireland's population fell from more than 8 million to just 6.5 million from 1841-51. A century later it had dropped to 4.3 million. By the late 19th century, emigration was heaviest from Ireland's most rural southern and western counties. Cork, Kerry, Galway, Mayo, Sligo, Tipperary and Limerick alone provided nearly half of Ireland's emigrants. Some of this movement was temporary, made up of seasonal harvest labourers working in Britain and returning home for winter and spring. By the mid-1930s, Great Britain was the choice of many who had to leave Ireland. Britain's wartime economy (1939–45) and post-war boom attracted many Irish people to expanding cities and towns such as London, Liverpool, Manchester, Birmingham and Luton.

According to the UK 2001 Census, white Irish-born residents make up 1.2% of those living in England and Wales. In 1997, the Irish Government in its White Paper on Foreign Policy claimed that there were around two million Irish citizens living in Britain, the majority of them British-born. The 2001 Census also showed that Irish people are more likely to be employed in managerial or professional occupations than those classed as "White British".

As a result of the 2008–2011 Irish financial crisis, emigration from Ireland has risen significantly. Data published in June 2011 showed that Irish emigration to Britain had risen by 25 per cent to 13,920 in 2010.
