I'm going to give a brief summary of this, and I would invite my colleague, Madam Kong, to supply more information about that.
I believe that, with time and with all the mechanisms in place with the police forces in order to report through the uniform crime report.... The standards are given. There is training online. There is data validation that goes with them, individually, when we find there are big differences from year to year. There is a big process of data certification that goes with police forces. I would think that the mechanisms in place are very good at the moment, especially for an administrative data survey.
Of course, there may be room for improvement to that, but there is sensitivity from the respondents' side and a lot of interaction between the people working on the survey and the respondents. I think that what is in place is pretty good, but if there are other ways of improving it, I would ask Madam Kong to supply information about that.
