Demographics are a popular issue to talk about, within political, geopolitical, and economic groups, pretty much all have a concern of some sort. I would like to add history to that list to demonstrate how all of these come together, and what that might mean for the future.
Populations are not generic of course, and the self-identified differentiation between them is usually enough of a shorthand to see where practical considerations will lie, but there are also harder factors that will dictate the boundaries. These groups often have their own cultural spheres, their own hierarchies and leadership networks, and will find themselves on their own path in relation to others – even if they sometimes reside near one another geographically. There is often a geographical consideration, but it does not seem to be definitive compared to other circumstances; both material and spiritual.
