Tianjin should be somewhere closer to Beijing directly at the sea

It looks fine. If you look there you're not going to think it's anything else.

Level 77

Aug 1, 2016

Really surprised that Hong Kong has less than 10 million.

+28

Level 83

Aug 15, 2016

Hong Kong is extremely densely populated, but it covers a tiny area. Has about 7 million. It's global significance comes less from its size than its status as one of the world's great trade hubs and financial centres.

+16

Level 35

Feb 22, 2019

Actually it's 9.64 million. CIA knows all.

Surprised hardly anyone got Nagoya. It's very architectural. Lovely houses! I want to go to Nagoya... Dreamland awaits!

Or I could go to Cardiff. Lovely rain.

Level 67

Mar 26, 2019

I went to Japan last year, and it was the best trip I've ever taken. I did not come across Nagoya once in my preparation (guidebooks, etc.). I am positively baffled by it. I'm pretty good with geography and know most major cities generally, and am especially fond of Japan. Somehow I just totally missed this city's existence, both in my general studies and in my trip there. I took the Shinkansen all over that country and I don't remember hearing or seeing Nagoya. It's like the Mandela Effect in reverse.

Level 83

Feb 11, 2020

I'm quite certain Hong Kong doesn't have 9.64 million. As of mid-2019 the Hong Kong Census and Statistics Department records 7,524,100 people in the SAR and HK's urban area doesn't even come close to extending beyond the SAR. Indeed arguably the city's population is less than that, since some parts of the New Territories and outlying islands aren't even connected to the city's main urban core.

Level 67

Feb 17, 2020

I lived in Nagoya for a couple of years. Absolutely have no idea what beautiful houses you're talking about. It got the crap bombed out of it during the war, so almost all of its houses are postwar, and then some (they often rebuild houses in Japan that are only 20-30 years old).

It's the port for Toyota and a major industrial city. Interesting enough for being Japanese, but not much there that will draw a casual tourist that you can't do in Tokyo or Kyoto

Level 70

Jul 4, 2021

jmeillor13, if you took shinkansen all over Japan, you almost certainly went through Nagoya. Haven't visited Nagoya myself, but have changed trains there on the way to Kyoto after coming down through the Kiso Valley from Matsumoto (both of which I'd highly recommend if you're ever back in Japan).

Level 46

Jan 18, 2023

What is it talking about, Guangzhou being the largest city? Tokyo is the largest city. Guangzhou's metro area is only like 19 million

Level 90

Jan 24, 2017

It's also usually counted in the Pearl River urban area with Guangzhou, Shenzhen, etc.

Level 83

Feb 11, 2020

Hong Kong isn't counted in the Pearl River Delta conurbation. The territory of the HKSAR adjacent to Guangdong Province is largely uninhabited. The urban areas of HK and Shenzhen don't connect.

Level 90

Feb 11, 2020

I'll take your word for it if the source site citypopulation doesn't include it as part of the Pearl River metropolis, but the Tolo Harbor corridor from Tai Wai to Fanling/Sheung Shui connects to Shenzhen, as does the New Territory sprawl from Tsuen Wan to Yuen Long/Tin Shui Wai. Yes, there's mountainous areas between them but you'll find the same between Zhongshan and Zhuhai/Macau.

Level 59

Apr 2, 2022

I've been to 4.

5 if HK is part of Guangzhou.

Level 71

Oct 18, 2016

I find it hard to imagine a city of 50,000,000 people, how do they manage the sewers, transport, electricity supply, hospitals, welfare, road maintenance, police etc.

+13

Level 64

Oct 18, 2016

Keep in mind that this is an urban agglomeration. Guangzhou's population includes nearly the entire Pearl River Delta region consisting of Dongguan and Shenzen.

Level 89

Jan 9, 2017

Guangzhou's population does not include Dongguan and Shenzhen, they are different cities in every sense, I live here in Shenzhen and my girlfriend who is a local here is registered in Shenzhen and has nothing to do with Guangzhou. Shenzhen is more part of Hong Kong than anything as it is walking distance (divided by a boarder) in some places.

Level 77

Jan 17, 2017

Am I a giant nerd because when I envision this gigantic agglomeration of urban sprawl it immediately makes me think of the planet Coruscant?

Level 57

Jul 6, 2017

yes

Level 31

Mar 25, 2018

Is Coruscant the one between Jupiter and Uranus?

Level 67

Mar 26, 2019

The causation is backwards--you think of the planet Coruscant because you are a giant nerd, but you'd still be one even if it slipped your mind.

Level 71

Aug 11, 2022

no, you're a giant nerd for taking this quiz

Level 46

Jan 18, 2023

Shenzhen is separate from Guangzhou

Level 59

Apr 2, 2022

My understanding is that calling Guangzhou a city of 50,000,000 is like calling Los Angeles a city of 17,000,000.

It's really a region punctuating by places of urbanity and places of serenity/suburbia (especially in Los Angeles's case).

It has a large population because it covers a large area.

Level 46

Jan 18, 2023

Exactly! This would be like counting all of the Inland Empire as part of LA Metro

Level 66

Oct 18, 2016

Great quiz.

Where's Wuhan? Population is 10,600,000 aprox

+24

Level 25

Jul 3, 2020

throwback comment to when the entire world didn't know Wuhan for the wrong reasons. Good old 2016

Level 73

Nov 9, 2020

Yeah, Kataj mentioned "Wuhan" without even thinking of *that*. Lived in a different world.

Level 66

Apr 2, 2022

I think by now the entire world knows where's Wuhan.

Level 46

Jan 18, 2023

In many cases, Wuhan is the only Chinese city many Americans know of lol

Level 65

I must improve my knowledge of asian geography! Great quiz, though. :)

Wuhan, Harbin, Chongqing should be on there...and by the urban area approach so should the Rhine-Ruhr

Level 58

Sep 18, 2017

I believe Guangzhou is a province, not a country.

Level 74

Aug 16, 2018

It's a city. Guangdong is the province.

Level 58

Nov 19, 2017

New Delhi should just be Delhi.

Level 36

Nov 23, 2017

Good quiz but please be more lenient about spelling (I think sau paulo and daka should be accepted)

Level 71

Aug 23, 2018

The photo of the Baha'i Lotus Temple in Delhi shows its beautiful structure well. A massive building that is sometimes crowded with sightseers. What amazed me was the system of removing shoes and placing them in an underground storing system that is accessed by a slot at the side of the path. Retrieving your shoes takes only seconds, although they may have thousands of pairs.

Level 60

Mar 26, 2019

Yes, Lotus Temple is a bliss and I like it more than Taj Mahal. Taj Mahal is simple overrated

Level 43

Nov 17, 2018

I'm from London and our population is like 7 million...

Level 67

Nov 17, 2018

I always find it amusing when people say "I come from this place" as if that makes them more knowledgeable about its population. It might make you more knowledgeable about other things to do with the place, but have you counted everyone in London? Anyway, this population is from citypopulation.de. They count any area as one agglomeration if it is continuous "city" (i.e. land that is built on) regardless of where arbitrary and usually unchanging boundaries are drawn. Also it tends to account for the fact that a lot of people who don't reside in London commute there for work. It is entirely possible that at any given time there are at least that many people in an area that can be reasonably defined as "London", regardless of whether or not it overlaps the boundaries of Greater London.

Level ∞

Feb 16, 2019

The following cities are listed at 9.75 million or greater: Lima, Xiamen, Hyderabad, Chengdu, Bogota, and Chicago.

Level 83

Feb 17, 2019

There's a typo: The first 4 cities are listed with 45.6 m

Level ∞

Feb 17, 2019

Fixed, thanks

Level 75

Feb 17, 2019

accept Tientsin similar to how Canton is accepted

Level 43

Mar 26, 2019

just curious, is lima no longer a megacity? Is bogota one yet?

Level 18

Mar 26, 2019

Both of those cities do not have an urban population accumulation of 10 million. (YET)

Level 83

Mar 26, 2019

Megacities are cities that contain one million cities. At least that's what they would be if people knew what mega meant.

Level 76

Oct 20, 2020

...let's be charitable and say that is a typo. Still, be very careful when you're criticising others.

Level 83

Mar 23, 2021

Good advice. You might wind up interpreting a joke as uncharitable criticism otherwise.

Level 28

Mar 26, 2019

Great quiz!!!

Level 87

Mar 26, 2019

The island of Honshu never ceases to amaze me. Three mega cities and some 100 + million people on one island.

Level 83

Feb 11, 2020

It's pretty incredible. Java is also pretty mind-boggling - despite being about 100,000 sq km smaller than Honshu it packs in over 140,000,000 people, the megacity of Jakarta, and several other large cities like Surabaya, Bandung and Yogyakarta.

Level 63

Apr 21, 2020

Java literally has more people on in than all of Russia. All of it. Saint Petersburg to Big Diomede. The largest country in the world has a smaller population than the fifth largest island in Indonesia.

Level 71

Aug 14, 2021

I believe Java has an even higher population density than Bangladesh, which is pretty crazy. But even that doesn't hold a candle to the Nile River Delta, which is probably the most densely populated major region on Earth.

Level 83

Oct 16, 2021

I believe the Pearl River Delta surpasses the Nile River Delta in population density - roughly 1900 per sq km compared to 1600.

Level 25

Mar 27, 2019

Most quizzes accept "Daka" along with "Dhaka."

Level 65

Apr 16, 2019

Shouldn’t Lima be added?

Level 64

Aug 13, 2019

It was added then removed after dipping just under the 10m mark.

Level 77

Jun 19, 2019

Beijing 21 mil; Shanghai 24 mil; Guangzhou 14mil and Shenzhen 11 mil. Suzhou 12mil and Nanjing 8.7 mil. Tiajnin 16 mil and Wuhan 10.6 mil. Chengdu 14 mil and Chongqing (urba) 8.9 mil. Shenyang 8.4 mil and Changsha 6.9 mil. Hangzhou 8.7 mil, Wuxi 6.5mil and Xi'an 8.9 mil.

Level 55

Feb 10, 2020

You should update for Lima, Xiamen and Hyderabad.

(Citypopulation updated its page!)

Level 73

Feb 10, 2020

IAB to the rescue, less than an hour after the update

Level 64

Feb 10, 2020

Updated! Working through all of my city features.

Level 58

Feb 26, 2020

Anywhere I look for the Xiamen population, I'm told it's less than 4M? Am I missing something? I thought Chongqing and Shenzhen were both over 10M...??

Level 75

Mar 1, 2020

Shenzhen is included in the Guangzhou stats

Level 61

Mar 5, 2020

Xiamen's urban area is above 10 million while city proper is about 4

Level 66

Mar 18, 2020

man 33/37 only gives you 3 points, I guess you have to get 37 to get 5 and 36 or something to get 4. No way I am gonna get nogoya or tianjin... (other two I missed were karachi and lahore don't think I would ve thought of lahore, but karachi is getable)

Level 66

Mar 18, 2020

hm looking at the stats, it doesnt all seem above board. Not a natural curve at all. Things smoothly slope up from 0 to 6% for the amount of people that got a certain amount of questions correct, and then suddenly jumps to 22% for the ones with all questions right. (which looks to be atleast 15% more than expected)

Edit not that I mind getting a low score, before people accuse me of complaininng just because I didnt get more points, I dont really care about them, even if I have gotten 1 or 0 I would ve been fine with that, just decided to look at the stats because I like stats and graphs and wanted to see if I could figure out the actual needed number of correct answers. When I saw a really unanticipated curve (the 100% is allways more than it should be, but haven't often seen Súch a discrepancy)

Level 76

Oct 20, 2020

Hey Mr Sifhraven. I'm not so sure - there are plenty of more knowledgeable (nerdy!) people on here than I am, and I got 35/37 without too much trouble. The map is a huge help. I did not get Hyderabad and Tianjin. I may get them next time (and forget some others though.....)

Level 83

Mar 21, 2020

Breezed through this in a couple of seconds just now. What's so impossible about remembering two cities? You can do it. And there are so many big cities quizzes on this site I think that's why the scores are pretty high on average. I must have typed in Tianjin and Nagoya at least 100 times each coming to this site over the years.

Level 68

Mar 21, 2020

Wikipedia says Xi’an has twice the population of Xiamen. But on the quiz that’s not the case. Xi’an doesn’t even make the cut. Why is that?

In almost all other sources, a number of other Chinese cities/metropolitanareas have a population greater than Xiamen.

Level 26

Yeah thats what im saying, Shenzen, Nanjing, Chongqing, Wuhan, even Quangzhou are bigger than Xiamen, I've never even heard of it until now lmfao

Chongqing takes up an area bigger than Austria. It should not be counted.

Level 28

Level 55

Feb 24, 2021

2021, Chengdu and Ho Chi Minh City add themselves to the list!

Level 49

May 4, 2021

Just wondering, can you make LA an acceptable type in for Los Angeles? Seems like it should be there but it's not, or is it already used for something else?

Level 69

Jul 23, 2021

i don't think that's typically done on the site because two letters would be a bit too easy (both in terms of guessing and in terms of accidentally guessing it when you're going for lahore or lanzhou or lansing or goodness knows what)

Level 59

Apr 4, 2022

I do have a tendency to accidentally get Los Angeles when I go to type in Lansing.

Level 26

Aug 12, 2021

If im not wrong, Lahore, Bogota, Chongqing and Chicago are all above the 10 million mark

Level 46

Jan 19, 2023

Chicago is not, Chicago is only 8 million and its population is decreasing.

Level 72

Mar 2, 2022

Which cities dropped off and/or were added?

Level 66

Mar 2, 2022

Changsha, Wuhan, Chongqing, Hangzhou, Xi'an, and Bogota were added. Guangzhou gain a whopping 18 million people, so it must have swallowed a bunch of other nearby cities. Chengdu was removed although that was a mistake in the update and should be present :)

Level 66

Apr 2, 2022

What mistake? Is the source wrong?

Level 46

Jan 19, 2023

Guangzhou is incorrect on this quiz, and Shenzhen and Chengdu should both be present.

Level 56

May 16, 2023

Shenzhen isn't here because of the source.

Level 74

Mar 2, 2022

65.1 m, really wondering how cp.de calculated this

Level 46

Jan 19, 2023

Yeah for some reason he counts Shenzhen as well as Hong Kong and possibly Macau. God only knows why.

+11

Level 81

Mar 2, 2022

Where is Chengdu?

Level 66

Mar 2, 2022

Chengdu is the capital of the Sichuan province in China.

But in all seriousness you are correct, Chengdu is missing at 15.2m

Level 79

Mar 18, 2022

Yes - why does Chengdu not feature here?

Level 76

Mar 16, 2022

This is crazy. Why did China gain like five cities? Last I checked only like two were actually that close to 10 million. And I don’t know if I want to know about Guangzhou...

Level 46

Jan 19, 2023

When did you last check, 1988?

Level 74

Mar 29, 2022

Chengdu is missing despite being above 10M just wanted to let you know

Level 35

Apr 2, 2022

For someone whose age is almost 14 I think 34 is a good score

Level 58

Apr 2, 2022

"for someone whose age is almost 14" bro tried avoiding saying 13

I’m eleven and I got 100%

May 16, 2023

Whatever you can achieve is a good score :)

Level 57

Apr 4, 2022

Given that Chengdu is a "city" the size of Connecticut, I'm fine with it not being on here

Level 59

Apr 30, 2022

Instead you get Guangzhou, which is even bigger!

Level 46

Jan 19, 2023

And Guangzhou is counting Shenzhen for some reason!

Level 83

May 16, 2022

As others have said, Chengdu does appear to be missing. Citypopulation.de lists the population in the urban agglomeration as 15,200,000.

Level 47

Jun 7, 2022

No Chengdu?

Level 46

Jan 19, 2023

Add Chengdu please. Many have said it

Level 22

May 4, 2023

I forgot Beijing ._.

Level 56

May 16, 2023

Could this be updated to include Harbin? Harbin has reached 10,009,854 people on citypopulation.de.

May 16, 2023

Also, Chengdu is on the empty map version but not here.
