Again, the mode of collection for the general social survey has been the same throughout the years for all cycles. It's a telephone interview, and 30,000 people responded. I don't have response rates, but after an unbiased response study we do conduct a search to see if there are specific groups for which we have lower response rates, and this would happen definitely. We do report on those data limitations, and we can provide the committee with those methodological considerations because we do have, as part of the study, the things we did to look at whether this could have an impact.
