In terms of numbers, it's always an open battle, I think, in Parliament about the number of people we let in. You've made, I think, an inference that we're letting in far more people today than in the past.
I've done some research, and from 1860 to 2009, as a percentage of population, we let in 0.97% of our population; from 1900 to 1949, we let in 1.34% as a percentage of population; from 1900 to 2009, a little over 1%. The current rate today is 0.7%. So as a percentage of population, we're actually low by historical standards.
Now, the only possible explanation, if your testimony is accurate, is that we had far more people checking 20, 40, and 60 years ago than we do today. Is that the case?
