This is a thread for reference on historical statistics, as well as discussion of it; populations, GDP, demographics, etc. both hypothetical situations and real ones. I will aim to compile all the information that can be offered, as well as the ideas and thoughts that need to be taken into account from debates. Essentially, the hope is that the thread can become a convenient point of reference for those who need to find historical statistical information for the RPs they're working with.
To clarify, discussion of "what if" situations is perfectly fine, as long as its within the rough bounds of these statistics; even if you need information on some future populations, demographics or GDP, that's fine here.
