Citizenship and Immigration committee  No, not on that one.

Citizenship and Immigration committee  If we knew that, yes. If we knew the precise immigration history, marital status, all the things that we normally would see if we were doing a review of them, that would help with the number. But we don't have that from census data.

Citizenship and Immigration committee  That's right.

Citizenship and Immigration committee  That's right. The only accurate number we would have, if we turned to administrative records, is the number of cases that are actually under review and on which some decision has been made, and that's a very limited number.

Citizenship and Immigration committee  No.

Citizenship and Immigration committee  I don't have any numbers for that one. That's probably going to come out of administrative sources as much as anything, if one kept good data on that, but I'm always worried about the administrative sources, because they have very special functions as to what they collect; when I turn to them as a demographer, I often think that it's not that the numbers are wrong, but just that they're very limited and very specialized in their use.

Citizenship and Immigration committee  Good morning, everyone. I appreciate the invitation to be here. I'm going to cover three topics. I'm going to give a few introductory comments. I'm going to summarize some key numbers very briefly, handle questions, and then I'm just going to express a few cautions. My training is as a demographer, with my academic research in demography primarily in the area of immigration.
