What is being measured in that graph?
(GDPpc)² * (population) ?
As far as I understand, It is the GDP (of a country) times the GDP of that country per capita, and then normalized. For example ChinaGDP * ChinaGDP/Chinapopulation is 10 times smaller than USGDP * USGDP/ USpopulation. This paper argues this is a better predictor of power projection.
Whoops, fixed my formula, I had it the wrong way around.
GDP times GDP per capita equals population times GDP per capita squared.
But I don't see how that translates to "net resources".
In this article I gave that introduces this metric, it has some explanations as to why they think this is a reasonable metric, though I don't think that it directly corresponds to "net resources". I think the point is that having a larger population to take care of requires more resources, hence making it more difficult to project global power, when comparing 2 countries with similar resources.
I'm partly through reading it.
Now that I think about it, it might be the key to being able to answer "does GDP alone make a country wealthy, or does GDPpc alone make a country wealthy, and how does a low-population-high-GDPpc country compare to a high-population-low-GDPpc country".
I think I would have made it ln(pppGDP) * ln(pppGDPpc).
