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 70
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.

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

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

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.

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.

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.

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

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)

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)

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.....)

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.

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?

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?
+3
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)

I think it's not because of length (BH is accepted for Belo Horizonte), but because of how common LA is like you said (BH is pretty much just in Bhutan).

Also, Hanoi is coming in hot with 8,435,700 in the total municipality (rural+urban), and 4,138,500 in the urban area! The metro area population is 20,000,000, though, so it's technically already a megacity if you're going by metro area. Good luck, Vietnam!
