So where's the math in all this?
We clearly need better and more reliable global data.
However I'm skeptical that partitioning the world up into a jigsaw puzzle and collating by "nation" is an at all useful way to be measuring humanity's progress or lack of same.
The UN has to do it that way, for political reasons, but supranationals like Google (or some hypothetical Global Data Corporation) would not need to present and/or visualize global data in those obsolete terms.
