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.

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.

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.

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.

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

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.

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.

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.

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.

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 58
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.

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.
