Normalizing the world’s statistics in these creative ways looks interesting:

To clarify the above chart:  when they say “nationality”, they simply mean the total population of all the countries that belong to the location shown.  But this definition of the continents is not the one I generally agree with.  I was told from school that there are six continents, not seven.  This is because in actuality, the continents of “Europe” or “Asia” do not exist; instead, there is “Eurasia.”  This still makes perfect sense to me since the line separating Europe from Asia (along the Ural Mountains) is completely artificial and has no real basis except for politics or the way the world was discovered in the past.

Wikipedia summarizes different views on this subject in this table:

While none of that really matters, I agree with the following definition of continents:

“The most restricted meaning of continent is that of a continuous area of land or mainland, with the coastline and any land boundaries forming the edge of the continent.”

If this definition is used, the entire area on the right of the top image will be green.
