World Circle Radius Population Challenge

Directions

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 10×10 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.

Enter guesses above to begin.

World City Grid 2nd Largest City Challenge

Type 'easy' or 'hard' to begin the quiz. Easy is a 15-degree grid, hard is a 10-degree grid. Then, try to name the SECOND LARGEST city in each grid square. To name a city, you must first click on the grid square to make it have a GREEN border. Then, type in the city answer for that square followed by a '.' (a period). You are given a score from 0 to 100 based on your answer's population compared to the 2nd largest city accepted in that square (100 being you named the 2nd largest city). If you guess the largest city it will be based on the ratio of the 2nd largest city's population to the largest.

At the end of the quiz the 2nd largest city will show in each unanswered square, and for those answered the 2nd largest city will be listed next to your score if you didn't answer it.
