I would have to double check to give a definite answer.
I can give you one statistic today that has been provided by the parole board. Of all the files processed by the board for pardons, they've been able to ascertain that 25% of the files relate to persons with more than three convictions. It gives you an idea of the magnitude of people with multiple convictions beyond three.
In terms of other characteristics of that group, it's something I would have to look at.
