The object of this quiz is to adjust each circle's diameter so it splits the circle's European population as evenly as possible. When you click Start you will be shown a marker on a random world location. Also you will see an circle between 100 and 1000 km radius. Adjust the diameter by rotating it using the endpoints, trying to split the halves into equal populations. Then click submit. You are scored on how close you have split the circle into 50% population in each half.
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.
Leiden doesn’t have anywhere near 250 to 500k inhabitants
Netherlands uses urban centres as the closest thing to cities, Leiden’s is that size: http://citypopulation.de/en/netherlands/cities/
Arnhem Zuid is not a city or town by itself, just the southern part of Arnhem
Netherlands doesn’t really have “cities”…it has urban centers, and Arnhem Zuid is classified as one.
I live quite nearby. Nobody classifies Arnhem Zuid as seperate from Arnhem. It’s just a part of Arnhem
https://nl.wikipedia.org/wiki/Arnhem-Zuid
the Dutch census however does for some reason…http://citypopulation.de/en/netherlands/cities/
I’ll just accept it with ‘Arnhem’ now though 🙂
same goes for Zwolle Stadshagen and Hengelo Noord, those are just neighbourhoods aswell
They are counted as urban centres by the census, which is the closest thing Netherlands has to cities.
you’re absolutely right
I’ve updated this quiz to use Dutch ‘urban centers’ instead of municipalities – these are much closer to other countries’ definitions of ‘cities.’
