"While there are 191 nations in the world, just 40 significant mega-regions power the global economy. Home to more than one-fifth of the world's population, these 40 megas account for two-thirds of global economic output and more than 85% of all global innovation."
UNQUOTE
Interesting idea: that mega-regions are actually more significant as drivers than nation-states when discussing economic competitiveness.
