No. I said there were two factors, Mr. Chair.
The first factor, as I said, was the impact of a declining response rate. The first consideration is the impact on the accuracy of the data through sampling error. I said we've taken measures to correct that. The second issue is the issue of response bias. We've heard a great deal about that. The reality is that you cannot say, concretely and absolutely, that the decline in the response rate will result in a problematic degree of non-response bias. You can't scientifically say that.
