The object of this quiz is to adjust each circle's radius so it contains the target population shown at the right but ONLY within Europe. When you click Start you will be shown a marker on a random populated Europe grid square (there are over 90K 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 100 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 5 and 100 million people. Then click submit. You are scored on how close your circle's population is to the target.
PLEASE NOTE: ALL of Turkey is included in counting population (not just European portion), and the portion of Russia west of 61.5 degrees E (just east of Chelyabinsk). Nothing outside Europe (such as Africa or middle east other than Turkey) is included toward the population count within a circle.
Why does Lisbon not work? I don’t find it possible that Seville is larger.
Seville is the larger city by city proper population.
why does porto not work
not the biggest city in that square
its vigo
because most of porto and lisbon are actually different municipalities, which makes them pretty small in these kind of quizzes
Why does Tampere in Finland not work? Should be the biggest in the square between Helsinki and Turku on Intermediate…
