The object of this quiz is to place 20 circles of radius 1000 km on the map so that they contain the largest total population.
When you begin you'll be given a 1000-km radius circle centered on the map. Move it using the mouse and click SUBMIT. You will be given a score for that circle corresponding to the total population contained within it based on world population density at https://human-settlement.emergency.copernicus.eu/index.php. Try to complete all 20 circles with the highest total score.
Any INTERSECTING areas are only counted one time, so no population will be counted more than once.

ooey this was a fun one! just one note from what I know – while it forms the majority of Cangshan District, I believe the island itself is known as Nantai. 🙂
Ah – I will allow both.
I thought the island was Britain. Not Great Britian. Doesn’t that include northern Ireland?
nope it’s Great Britain.
Disagree…. Britain = physical island. Great Britain is the political union within the island (England + Scotland + wales)

That’s the United Kingdom
in the future will u put Istanbul there too? U know, the turkish government is making a new channel that cuts the city and makes it a island.
yeah perhaps if it is regarded as an island then.
Is there a version of this with a map?
not for this one thought that would make it too easy then you really aren’t thinking about populations just naming islands.
