Honestly, I have not done research on that so I'm not 100% sure. From my experiences in Australia versus Canada, it's about equal.
Each person is an individual, so I can't speak to when they'll have needs or what not, but it definitely will make everybody safer. I've experienced that first-hand. Being in Australia, everything was quite lovely. The clients were awesome. I did not come into contact with anybody who was underage or trafficked. Immigration was very pointed about that.
As for the clients, it was roughly about the same numbers in my books, from what I've experienced.
