compare those densities with Dhaka:

City Population: 7,000,940
Density: 45,508/km2 (117,865.2/sq mi)

Hong Kong is made up of thousands of km of open countryside, and 236 outlying islands. Not only that but that countryside is entirely empty - the percentage of the population that is urban is 100%.


Hong Kong urban area: 137 km2
Population: 7,018,636
Density: 51,230/ km2 (132,685/ sq mile)

Tokyo

Manhattan

Paris
- Total 2,203,817
- Density 25,360 /km2 (65,700 /sq mi)

75, 92, 93, 94 is what counts as "city" (2,2 mil) and we have density data for that only and not for the entire metro area of Paris (12 mil). That's why I put Paris next to Manhattan until we get metro data so we can compare it to NYC.

I'm wondering why the urbanized area directly north of Paris is not considered part of the metro area of Paris, but it's closer to Paris than the rest of other parts around it that are considered metro Paris?!?

Ouch! 7 million people in such a small area, denser than Manhattan or central Paris!

LOL, exactly ad nauseum! Some people do not give statistics too much thought! Thanks for the data..

I was wrong about the city limits. Only 75 is "city" (2,2mil) and I've also found density data for Paris metropolitan area.

- Total 11,794,000
- Density 973.5/km2 (2,521.4/sq mi)

And NYC metro:

- Total 18,815,988 (2007 est.)
- Density 1,077/km2 (2,792/sq. mi)

Perhaps French people would like to answer the question about Paris metro limits? Anyone here?

However.. the data that you used for urban area was very old. It has expanded quite a bit after a lot of development (new buildings). So many 30-40 floor buildings have been built within the last decade--perhaps as much as 70% of all the existing 40+ floor buildings are less than 10 years old. Many of them have been built on hillsides, resulting in less forested areas.

Some other sources state that the current urban area of HK is anywhere between 100 and 130 square miles, which makes much more sense after looking at Google Earth. The total land area of Hong Kong is just over 400 square miles.

Interestingly, Kowloon has been becoming less dense as HK continued to expand.

The urban area density of the entire developed area of HK is anywhere between 55,000 per sq. mile and 66,666 per sq. mile after taking the newly expanded urban area into consideration.

I was watching a show on Mumbail (Bombay) Railway the other day and they said certain parts of that city exceed one million people per square mile, which would be right up there!

Interesting...

http://www.huawei.com/success_storie...eneral_catalog

"The main urban area of Hong Kong has a complicated radio environment with a population density of 250,000people/km2, a building density of 630 buildings/km2, and an average building height of 45 meters."

What source please?

So youre saying HK has tripled in size in 8 years?

Here's one source that gathers data from like 8 different sources:

http://en.wikipedia.org/wiki/List_of..._by_population

Wiki links to several sources that link to several others. I've personally seen it from 3 different sources. Looking at Google Earth and judging for self also does some good.

272 square km translates to 105 square miles, which is roughly 1/4 of the total land area of Hong Kong territory, which looks exactly right after observation.




I could also try to subtract all the park area from the total land area of Manhattan to do similar adjustments. Manhattan and the Bronx are two city districts that are the most highly consisted of parks--the percentage is among the top for the large cities of America (if not the top 2, IIRC..).

Anyways, here's some exciting data: http://www.demographia.com/db-hkca.htm

Why don't you use district information for Hong Kong? You can clearly see the dramatic difference in density from district to district.


source: http://en.wikipedia.org/wiki/Districts_of_Hong_Kong


Aerial of Mongkok

Quote:
Mongkok is not only Hong Kong’s most populated area, but the world’s. According to the Guinness Book of Records Mongkok is the most densely populated place on the planet, squeezing in over 130,000 people per km2.

That translates to 336,000 ppl/sq mi
In comparison with some central Shanghai districts

New Huangpu - 12.41 kmē with 574,500 = 46293 ppl / sq km
Luwan District - 8.05 kmē with 350,000 = 43478 ppl / sq km
Jing'an - 7.62 kmē with 305,300 = 40000 ppl / sq km
Zhabei - 29.26 kmē with 810,211 = 27690 ppl / sq km
Hongkou - 23.48 km2 with of 799,700 = 34058 ppl / sq km

I misread your post Shera, I thought you said HK urban was 400 sq. miles (hence why the city would have grown 3x it's size)

Unfortunately, Mongkok is no longer an "official" district. It was combined with another district in 1996, into Yau Tsim Mong, which is a bigger and less dense area overall (less dense than the entire urban Kowloon).

Anyway, you missed out on the link that I provided in my previous post, which stated an SAR constituency area (Tsuen Wan Centre) with 1,127,686 per square mile!!! That's probably the world record for a census tract!

Here's the link again:

Gukanjima is fascinating, same with the former Kowloon Walled City.

At it's peak, the ancient city of Rome is thought to have had a population of 1 million in an area of about 426 hectares (1.64 sq miles). The population density would have been about 609,756/sq mile.

About Kowloon Walled City... Were the ceiling heights in some levels about 5 feet high or less? If you look at the ground level it looks normal height, but the floors above look like you would have to crawl around your apartment.

This is what remains of the Walled City now, the centuries old buildings and foundations of the original village under the illegal add-ons:

^ I think that's normal camera distortion, things closer appear larger than normal.

Even those HK-provided numbers clearly include a lot of wilderness in many of the districts. That's obvious when you see that they call Wan Chai 9 sq km for example.

Lennox Hospital? I'm not exactly sure. Lots of people in a hospital, eh?!? Hunter college? That's all I can remember on Lexington/Park Ave in upper east side--the richest people live there. Super-expensive hotels there also. That hospital is like the richest hospital in the world, only for millionaires.. LOL

Hmm, now it doesnt make sense for a hospital to have so much more during daytime, when it's nearly as active during night. Gotta look it up.. yeah, the hospital is a bit further north than that red spike in upper east side. Looks like Hunter college?
It's not Lenox Hill hospital, that's further up. Maybe it's the Guggenheim Museum. It's along 5th Avenue on the E. side of Central Park. But I can't see it being that packed.
