The Minister has fallen into my trap, and I should like to thank him for that. The figure is 15,000. Is the Minister aware that on the last occasion when Fianna Fáil were in Government figures became available as to gross emigration from here, and that the figures that emerged in the census of 1971 showed that 25,000 people on the date of the census had been elsewhere a period of 12 months earlier? Is he aware that in that period net emigration had been 4,000 from which it is arithmetically evident that a gross figure of 29,000 people emigrated as against 4,000 net, and that, therefore, the figure of 15,000 is, if anything, inclined to be an underestimate? Is the Minister aware of those census figures and of the fact that those figures show that gross emigration can be seven times net emigration?
