There are several factors that we were not able to take into account when conducting the analysis. Prior conviction history, as I mentioned, is one that we are not able to take into account.
In interpreting the results of this graphic, one has to be cautious in the fact of keeping in mind the type of offence. We don't control for type of offence, as Michael has already said. So we have to keep in mind those factors that we weren't able to control for while we conducted the analysis.
What we do show within this analysis is the proportion who were reinvolved within the correctional service within a particular period of time. Whether or not the factors that result in a return to the correctional service or a non-return have to do with the prior history, with the nature of the offence, or with the circumstances surrounding it is very difficult for us to tell with these particular data.
