I goddamn love this ridiculous fake country obviously made by a teenager! A few additional details I've figured out about Brittanica that I don't think the creator thought of...
78.6% of the population lives in one of the 10 largest cities.
It has the 8th highest population density in the world at 723 people per km2.
It's physically about the size of Cambodia.
It is the 10th most populated nation in the world, between Russia and Mexico.
There are somehow more people living in the city of Klahoma (25 million) than in the state of Klahoma (15.2 million).
There are more cities with a population over 10 million in Brittanica (5) than in Brazil (2), Japan (2) or the USA (2). The only countries with a comparable number of cities of this size are India (5) and China (6), both of which have populations of over 1.3 BILLION people.
What I'm saying is this country is apparently composed of ten or twelve cities that are absolutely jam-packed with people and then vast tracts of uninhabited wasteland...
