World 10 Circle Population Challenge
DirectionsThe object of this quiz is to place 10 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 10 circles with the highest total score.
Any INTERSECTING areas are only counted one time, so no population will be counted more than once.
