The distribution on this forum is likely not representative, probably even going to be misleading.
Some countries (or language based groups) have there own forums, and may be less represented here.
E.g. there is a separate Chinese forum. And afaik Brazil has a rather large community, but it isn't on your poll list.
You can also get some ideas from the download stats on sourceforge. Though they are not representative either. There are alternative mirrors, and other install options (e.g. git, or Linux repo). And depending on region people may have different opinions on Sourceforge itself, which then reflect in the statistics as they may be more or less likely to download there.
