Nice! Would Ulaanbaatar be considered in central Asia?

No I consider Mongolia as part of East Asia, otherwise it'd rank 6th ahead of Omsk.

Mongolia's culture I would say is a mix of Central and East Asia. But geographically, I think it should be East Asia.

I was contemplating putting Mongolia and Xinjiang in Central Asia, but the East Asia map would look weird and what am I going to do with Tibet?

I agree that Mongolia is geographically speaking in East Asia rather than in Central Asia.

However about separating parts of China (regardless on whether they have a large percentage of people of a certain ethnicity in these parts) is something different. Then you would have to do this to parts of other countries too to be consistent (e.g. Alaska, Northern Canada, Greenland, Northern parts of Nordic countries, Russia, etc.). Northern Africa and the rest of Africa can also be separated and if you really want to separate by ethnicity then there would be more divisions than countries in Africa and Asia.

Nice Quiz! Can you please accept DC for Washington? And maybe Cologne for Essen as according to JetPunk, they are in same urban area.

The type-in for Washington is automatic. According to the source, Cologne is a separate urban area together with Bonn and has a population of 2.1 million.

But DC is acceptable in other featured quizzes

"DC" is only accepted if the answer is "Washington, D.C.", which is probably applicable in a capital city quiz. But in this case the urban area of Washington + Baltimore is much bigger than the District of Columbia.

Fantastic quiz, I really enjoyed it, will nominate!

I have two comments though:

-I see that Hawaii has been placed in a region with Oceania, even though it is a US state. But sure, you decided to go along with this. However if you decide to go along with this, I think it is a bit inconsistent to place French Guiana with Europe as it is in South America. I also don't understand why Suriname is with North America rather than South America.

- I was not able to check your source, I can't open it. But either way, Onitsha is not one of the top 10 most populated urban areas in Africa, it also does not make the top 5 in Nigeria. You might want to edit this.

Did not check any other mistakes but there might be some other minor mistakes, I recommend double-checking. The quiz was fun, thanks for creating it!

According to the source, Onitsha population is 6,887,000. It in turns sources its African data from africapolis.org, which has Onitsha population at 8,530,500 and covers huge neighbouring areas including Nnewi and Owerri.

Would not call this an "urban area." Moreso a bunch of villages near a medium sized city.

I also think onitsha is wrong, https://www.macrotrends.net/cities/22013/onitsha/population

How the hell does Onitsha pass Accra, Abidjan, Yaounde, Kampala and Cape Town?
