So, without getting into /pol/ territory, are there any social scientists here?
I'm looking at this graph here and I'd like to know a few things.
>1
How accurate are these demographic change predictions?
>2
What are the social and economic implications of demographic change to this degree?
>3
Is there any historical precedent for demographic change like this, and if so, what were the consequences?
>4
Is demographic change like this over a ~100 year period (the bulk of which will occur within our lifetime) something to be legitimately concerned about?
>5
What factors, if any, are contributing to this demographic change?
>6
Are you personally concerned about this?
