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.
Why is Seoul(almost 10M) only 539km? Cities over 10M(Tianjin or Shanghai) will be at least 800km away.
oops – i had miles instead of km – fixed now.
Where is Johannesburg? Or what is it called?
it’s actually Soweto. the city proper population is a little higher than Johannesburg
I really like that you can see some that you missed at the end!! Wish the city coverage quiz had that too.
I’m sorry, I’m slowly getting used to the quirks of this website. But Nasinu over Suva? Really?
Nasinu is now actually a larger municipality than Suva. Suva’s metro area may be larger, but my city quizzes use city populations.
