World Circle Population Selection Challenge

The object of this quiz is to click on the circle containing the largest population. When you begin you'll be shown 2 circles with radii between 100 and 2500 km on the map which do not intersect. Click on the one with the larger population within it (based world population density info) then 'Submit' - if you are correct you'll move on. One incorrect round and the quiz is over. Every 5 rounds the number of circles on the map will increase by 1. Try to build the longest streak of correct circles. Circles displayed will always be non-intersecting.

World Grid Population Challenge

First choose a grid size by typing '30', '20', or '10'. A grid of that size lat/long will be placed on the map (so if you choose '20' the grid width and height will be 20 degrees). Then, double click on the grid square with the highest population within it (based on world 10km x 10km population density estimates). The highest-population remaining square will give you 100 points, all the way down to 0 for the one with the smallest population. Try to obtain the most points by successively double-clicking on the highest-populated grid square.

World Circle Radius Population Challenge

The object of this quiz is to adjust each circle's radius so it contains the target population shown at the right. When you click Start you will be shown a marker on a random populated world grid square (there are over 800K 10x10 km grid squares used for the data, courtesy of https://human-settlement.emergency.copernicus.eu/index.php). Also you will see an adjustable circle of radius 500 km to start. Adjust the circle's radius by dragging it until it contains the target number of people shown - this target will be between 2.5 and 250 million people. Then click submit. You are scored on how close your circle's population is to the target.

Hey, its a little bit weird, that cologne gets accepted for ruhr, because Cologne is definitly not part of the Ruhr-area, which, more or less 50 km north of Cologne, ranges from west (duisburg) till east (Dortmund) with relatively little north-south-extent, containing as biggest cities Dortmund, Essen, Duisburg and Bochum (amongst several others over 100.000 population).

The source site (citypopulation.de) changed to include Cologne as part of the Ruhr agglo, and not its own separate one.

Hey Darren, mind adding the source for this one? Doesn’t seem to be Demographia’s World Urban Areas list this time.
