| @Trifun Karaevski: The quiz used to be based on city limits but this doesn't work well. Different countries define their city limits in different ways, which leads to an arbitrary quiz. For example, the Ukraine defines city limits very widely, which means that five or six of the top 25 were in the Ukraine. Germany, on the other hand, hasn't changed the definitions of its city limits for a long time, so they're based on how big the city was at some arbitrary point in the past. Many of the cities have become very large but have out-grown their formal limits. Places like Frankfurt, Dortmund and Stuttgart are larger than any Ukrainian city but a lot of the people live outside the formal city limits (even though they're still in heavily urban areas) so these huge cities didn't even appear on the old quiz. Likewise, Athens is one of the largest cities in Europe but, technically, has only about 770,000 people. The other two and a half million live in Piraeus, Zografou, and so on. But there's no obvious boundary between these places (just look on Google maps!); the urban area corresponds much more closely to the idea of "city" than does the boundary of the Dimos Athinaion. |
