Like all questions, the answer is "depends". :)

E.g. number of kids falling and breaking their arm will be larger, but the population is larger and medical care is better, now. So, overall, I think the risks are actually lower than when I was a kid running around unsupervised.

I don't know about the number of pedophile predators per capita, but I imagine that may be a roughly fixed proportion of the population. Kids now also have cellphones, so that's a lifeline kids never had in the past. So, I'd imagine that percentage would not really rise, either.
