This forum is meant to represent yourself. If you have a technical question use the other forums, and if you have a homework-related question, use the homework forums.
However, our rules require some effort from your side in any case. The question above would be dismissed for that reason because, to begin with: What made you think (will say: do you have any evidence!) that it differs from the general average in the corresponding country? See, not only is there no published study we could discuss, but it also depends heavily on time and location. There is no chance to discuss your question in any serious way, which is what we are trying to do here.
