There are statistics showing which countries have the most scams. This does not characterise the people living there in a bad way. Although from the point of view of ignorance at the expense of which any scam lives, these countries do lag behind to some extent. It is ignorance that allows scammers to deceive people who are too lazy to learn. It is these people who become the first victims of any scam.
I think we don't need such statistics. The number of scammers in all countries will be approximately the same, but not everyone has access to the necessary means of distributing such information. Very often, people become victims of scammers when they lose hope of earning money in a legal way and use such Ponzi schemes as the last opportunity to fix their financial situation.
