In Germany, you're missing the Ruhr Area, which is (according to your source) the biggest urban agglomeration of the country.

Nitpicking aside, this is a great quiz :) Goes beyond the usual range of countries and also visually pleasing

I agree that the Munich urban area has more than Stuttgart. I looked up the populations of Stuttgart and its main suburbs/attached towns, and it was only a million or so. I think they are including Heilbronn, Tübingen and Reutlingen, but there is a lot of countryside between those places and Stuttgart.

China should be Chongqing (31 m), Shanghai (24 m), Beijing (21 m), Chengdu (20 m) and Guangzhou (18 m). Xiamen is a rather small city with six million inhabitants.

Chengdu does appear to be more highly populated than Xiamen by any measure, according to multiple different web pages I found. (I've never been there, mind you.)

I was a little skeptical of the Filipino data, which didn't match what I previously thought, as well as data from sources I looked into.

I would recommend not having both Brazil and Portugal since Porto Alegre and Porto overlap. Although I would guess most people who know Porto Alegre know Porto.

I've done this for 15 minutes and got 180 just to find out that it doesn't count, because you changed Upper silesia and cologne in the meantime.

Good quiz though, and it's always nice to see my home city as an answer

Not that it's that huge a deal, but in case this quiz gets some edits in the near future, the Syrian flag should be updated as well. Nice quiz to feature regardless!

Fantastic quiz, very challenging time constraints too, I think I wasted a bit too much time trying to do the first few country-by-country instead of just boxing off all the ones I knew immediately and then working on stragglers. Got 172/222; think I could've gotten that up to the 4-point boundary with better use of my time, some glaring omissions on my part from rushing towards the end (I got Coimbra and Kaohsiung but missed Gdansk and Innsbruck lol)

What's the source for Xiamen being the 5th major urban area in china?

As of today Feb.4th.2025 you mention citypopulation.de (which has different data) and wikipedia (which has different data - Xiamen is not even mentioned in the top 20 urban areas). And yes, I looked for urban areas, not city proper.

Honestly, it's pretty frustrating having to go through tenths of city names, since china has so many eligible cities, only because the definition is so loose, at least I hope this is the reason.
