The census portion of the 2011 census program was mandatory, and the response rates held up very well. They were in the high nineties, around 98%, for the 2011 census population per se.
For the national household survey, which was conducted on a voluntary basis, the response rate was around 69%. Strictly speaking, the way it was designed means the response rate was 77%, but without getting into the technical details of why the two rates are different, I'll just stick with the 69%.
Going to a voluntary survey did reduce the response rates, and the reduction in response rates has consequences in terms of data quality and the ability to publish data. Nonetheless, for survey research in Canada, that's a very respectable response rate. I have great confidence in the data from the 2011 census and the national household survey.
We don't really emphasize jail time. Penalties remain under the act; people can still be fined. In the wake of the 2016 census, a similar number of cases will probably be prosecuted. Of those cases, as in the past, probably two-thirds of the people will choose to fill out the questionnaire at the moment they go before the court. The others will ultimately be found guilty, and now they will potentially be subject to community service or a fine, not jail time.
We've never really focused on jail time as an argument to convince Canadians to participate, so I'm confident there will be no operational consequences for the mandatory 2016 census of population as a result of the removal of the jail time penalty.
