I'll speak to the second part of the question, how it can be improved.
A point I tried to make is that we need to look at this issue through an interdisciplinary lens. So we're talking a lot about reporting statistics, which is important to understand the magnitude of the issue, but what are we doing in psychology? What are we doing in social work? The front line workers, how are we assessing the effectiveness of the programming that they're providing? From education, what needs to be embedded in curriculum as an awareness campaign? How do we reach youth on social media?
I think that data collection really needs to look at mobilizing, and I mentioned the academic community because that's where you can find folks doing work that intersects with these areas. I know folks who are doing great work in youth homelessness at York, for example, and they could provide information on trafficking. So just finding mechanisms and avenues for folks who are doing research in those areas related to trafficking would be helpful.
