Houston is the fourth largest U.S. city and it is more populous than DC. I’ve been in DC the past 20 years and lived in Texas for more than 33 years before that. My Census contacts work in a dangerous area here and provide many federal employees with accurate data.

Mar 21, 2019
I don't personally know any census employees, nor have I ever lived in Texas or DC. However, I don't believe that this matters. The source of the quiz is listed, and if you go there, they list their sources as well. Ultimately, this data is coming from the U.S. government.

On my latest go at the latest version of this quiz I got 48/50, missing Chennai and Luanda. This despite having hung out with someone from Chennai just two nights ago. Oh well. It seems everyone of these larger list quizzes, there's always one obvious answer I miss. At least this time it was't Beijing like on a past attempt.

The Guangzhou Agglomeration, which has a population of 46,700,000 includes the cities of:

Shēnzhèn - 13,374,300

Guăngzhōu - 13,233,500

Dōngguān - 7,795,800

Fóshān - 7,750,700

Zhōngshān - 2,987,900

Jiāngmén - 1,650,000

This adds up to 46,792,200, which is around 46,700,000

Nov 15, 2020
The list cites the 2019 version of the website, but that version is no longer accessible - only the 2020 version. I suggest updating the quiz to match. It involves a few citiies changing places, and removed Riyadh in favour of Shenyang. Also, it gives local names and English names. Some of the English names are accepted, some are not. E.g., the list gives Tianjin=Tientsin, but this quiz rejects Tientsin. At the same time, it the quiz accepts Calcutta (=Kolkata). I suggest that all English names given be accepted alternates.
+1
Level 62
Apr 10, 2021
Tientsin is not the English name for Tianjin (which is the english name), as opposed to 天津。 "Tientsin" is just a romanisation which as fell out of use.
+1
Level 53
Mar 13, 2022
Yes. citypopulation.de says that the "English Names" are the former names (eg Madras for Chennai, Bombay for Mumbai, Bangalore for Bengaluru), but I call them by their (now common in English) names.

I lived in Xiamen a few years - it isn't that big. I'm guessing it was combined with Zhangzhou and maybe another? Most Xiamen folk would be surprised to be on this list.

According to citypopulation.de, Xiàmén is combined with Jìnjiāng and Quánzhōu.

Wait... Why does Seoul has 25 million populations? Seoul only has 9.8 million... 25 million populations are in the South Korea's Metropolitan area which contains Seoul.

I don' think Seoul has 25 million populations.. It is not even a megacity now! I think the population of Seoul included Gyeongi-Do whose land covers Seoul. If I am wrong, please tell me why :)

If you connect all the parts of the city into one - this is how all the other cities are counted also, with all the connected towns and cities combined into one so long as they are touching. The NYC count for example takes in huge parts of the countryside, without even having to touch each other, that's the size of a small country. -Seoul is much more contiguous: https://www.dreamstime.com/high-resolution-satellite-image-seoul-metropolitan-area-south-korea-aerial-background-map-contains-modified-copernicus-sentinel-image155221570

I agree, the capital is New Delhi, but the urban agglomeration is centred in the larger Delhi, of which New Delhi is a part of. The city also includes: Faridabad, Ghaziabad, and Gurgaon.

Mar 3, 2023
Please stop using citypopulation.de for these, mostly because it is wrong about Guangzhou. Guangzhou is large, but it is not larger than Tokyo, and Shenzhen is its own city, it is not part of Guangzhou.
+1
Level 69
Mar 28, 2023
These are urban agglomerations, not the city proper or an urban area. An urban agglomeration follows a different ruleset; such as a connected population geographically, culturally, lingually, and politically. Shenzhen would fall under Guangzhou's UA in this case as they are one large area of continuous urban area, speak the same language, are under the same government, and travel between the two is very easy. Urban agglomerations are NOT the same thing as urban areas.
