It is a good project in itself

such as with the CSA industry. They will gladly write all this nonsense about how they're helping children so much (by restricting their rights) but I bet it's harder to find a report containing the figures of money that are made from the CSA industry.

I don't know if there's exactly a report on this.

However, it shouldn't be too difficult for someone with enough time.

The CSA industry can be divided in the following:

-- Governmental multi-disciplinary agencies whose mission is CSA. (I am thinking on ncmec and similar when I say this)
-- NGOs devoted themselves to CSA.
-- International agencies devoted to CSA.
-- Professional psychologists specialised in CSA, if they don't already work in the above.
-- Police units devoted to CSA.

Police and governmental agencies are subject to public scrutiny - well, not in reality, but they DO have to publish their own budgets in order to meet the demands that lawmakers and national treasuries require of every instance of government. Therefore, you can research those figures for yourself - might be much more complicated, of course, if either or both are divided or shared between national and local levels of government. International agencies are also subject to that kind of scrutiny by the governments that fund them, so they too publish those budgets.

Recognised NGOs also have to publish their budgets, for the sake of being transparent to potential donors as well as to get any tax exemption status they want.

It might be harder to get the figure for psychologists working CSA in a private practice. What I'd suggest to do is try to get a number of them by asking either governmental agencies or NGOs how many there are. Even if they cannot give you an accurate number for everywhere, if they can give you an accurate number for some places, you can later research the total number of psychologists for those places so as to get a rough proportion of private practice psychologists working on CSA - which, if it seems coherent to do so, might then be extrapolated elsewhere. In any case, once you get the number, all you have to do is make calls and see how much they are making.

Even if private practices cannot be determined, I think with the other four we might already be talking billions...

Now, where is the journalist that will write this???
