Thank you very much for that question, and I look forward to trying to explain it as clearly as I can.
I'm quite confident with the numbers that we have projected based on the information that's available to us. We have had an opportunity to review the Parliamentary Budget Officer's report, and I think, as you're quite aware, there are some differences, partly because there were certain pieces of information that we couldn't provide the Parliamentary Budget Officer as a result of cabinet confidence. Therefore, some of his calculations are based on some assumptions that are not the assumptions we have used in our process.
We've looked at many things in our calculations, including past trends in terms of overall population growth. You heard me mention earlier our normal population growth of about 1% for men and about 2.8% for women, and that's based on historical data and trends that are available to us.
As it relates to the bills I mentioned, particularly Bill C-25, we used a set of assumptions that are slightly different from the Parliamentary Budget Officer, and some of the assumptions the Parliamentary Budget Officer used are not ones we would use. For example, in the Parliamentary Budget Officer's report, he bases some of his calculations on about an 8,000-plus offender admission rate into CSC. Our admission rate is lower than that. His calculations actually include admissions for not only warrants of committal, new offenders coming into the system, but also individuals coming back on suspension or revocation from the community. So those are not new offenders; they're just offenders who are already in the system who are being suspended. So there's almost a 50% difference in terms of calculation from admission rates when you start to look at that.
As well, in his calculations, again based on the information that was available to him, he looked at using total operating costs for CSC as opposed to those that are directly linked to providing services to offenders at the custody and intervention level.
So those two areas create some differences in the numbers.
