I was curious as to whether there has been a significant uptick in arrests/convictions for human trafficking/child trafficking. Without spending a lot of time, I found this website that runs stats on all sorts of things. I had to do a quick screenshot save to get this, because they want you to sign up to view the graphs (but if you follow the right keyboard steps, you can quickly grab an image before the "sign up now" overscreen appears :) )

It's definitely going up, but I don't see an indication of a major jump yet (but this is only through 2019, so 2020 may show a big jump when the data comes in)
