HL Deb 10 December 1970 vol 313 c1159WA
LORD O'HAGAN

asked Her Majesty's Government:

How many citizens of the Irish Republic are now in the United Kingdom (including and excluding Northern Ireland); and how many are resident here.

LORD WINDLESHAM

The only relevant information is that the 1961 Census of Population in Great Britain showed that 684,000 persons enumerated had been born in the Irish Republic, and 42,000 in an unspecified part of Ireland. Of this total, 709,000 were resident in Great Britain; and this figure is estimated to have risen to 739,000 at the time of the 1966 Sample Census. In the Northern Ireland Census of 1961, 53,000 people enumerated had been born in the Irish Republic.
