I wouldn't call it a profile, because that casts a certain image to suggest that there's a recipe for it. It's a set of factors that officers take into account and try to balance in making a judgment about an individual's intentions relative to what they may have stated those intentions to be at the time of application.
I might add that 82% of applicants are actually issued visas. These are temporary resident visas. We consider most individuals to be very low-risk travellers. It's actually separating the low-risk from the not-quite-so-low-risk that's the challenge.
