Adjacent Capital Pair Superlatives

I know the title is a mouthful. Here's the deal. For each superlative listed, name the pair of national capitals in adjacent (touching) countries that match.
*Urban Area population according to citypopulation.de
^City Proper population according to wikipedia

Updated April 2015: expanded from 24 to 28 questions. Decided to remove the caveat about not counting French Guiana as part of France and just add an additional category instead. Also added the one about distance from the equator.

But Bogota is 511 km away. And this is about capital pairs. 511 + 28 (Quito) = 539. 35 (Kampala) + 143 (Nairobi) = 178. Don't believe me? Check out restlessmess's quiz on the subject.

Possible corrections: - Greatest popoulation difference: I would guess that Thimphu and Kathmandu are smaller than Beijing and New Delhi? - Maybe you should accept Lima, too, for greatest elevation difference? I know it touches the ocean but don't know if it's considered at 0 altitude Possible ideas: - Kinshasa and Brazzaville: I suppose you could put the second closest together cities (and the second farthest apart pair); or maybe closest together by country size (distance between them divided by sum of country ares?) - Capitals at the different sides of the equator/prime meridian (but maybe they're too many?) - Difference in average temperature Also, you could do a similar 'triborder' quiz where you consider capital of 3 countries bordering each other. Do you have a list of country borders in a good excel format or something? If so I'd be happy to use it for my quizzes! :P

Not sure what you mean by Thimphu and Kathmandu being smaller. In terms of population difference, using figures for "city proper" and at least according to Wikipedia, I don't think anything even comes close to Beijing vs. New Delhi. Wikipedia gives Beijing's municipal population as over 21 million. New Delhi, on the other hand, is really just a small neighborhood in the greater city of Delhi, even though it is officially the capital. New Delhi's population is a meager 250,000. That means there is a difference in population north of 20 million, and since there are no capital cities in the world with a population that large in the municipal boundaries (except for Beijing, Tokyo's municipal population is only 13 million), it's impossible that there is another pair with a larger difference. If you measure by urban area and not city proper of course there's a very different result.

Thimphu, capital of Bhutan is cca 80.000 (which is much smaller than New Delhi) and that means that the pair should be Beijing - Thimphu.

Though I appreciated the irony before of New Delhi and Beijing being the answer for both biggest total population (urban area), and biggest population difference (city proper)... since New Delhi's city limits are silly. It is a neighborhood within a city, not a city.

re: Lima, there is part of the city that touches the sea, but then there are other parts that are 1500 meters high. It's a very mountainous city.

re: your suggestions for other categories... 2nd closest could be good I might add that. 2nd farthest apart I'm pretty sure would just be Moscow and Beijing so that wouldn't really add anything while at the same time unnecessarily dropping a hint for the farthest answer.
Closest by country size? That sounds like it would take a *lot* of work to figure out, and I would have no idea who would win in that equation either. I don't think most people would even bother guessing, that's just too confusing.
The equator/meridian thing is a good idea but, yes, there are quite a few that would fit that description. That might be better as a subject for a different quiz.
Difference in average temperature is a very good idea. I may look into adding that one as well as 2nd closest capitals.

Triborder... I'll think about that, too, though again I think if we go too complicated people will just be confused and not bother with it.

This is what I've come up with for potentially the biggest difference in average temperature: Addis Ababa (up in the mountains, quite pleasant year round) has an annual daily mean temperature of 16.3 degrees Celsius, while Khartoum's average is about 29.83 C if my math is right, for a difference of 13.5 degrees. Runners-up include Sana'a/Muscat, New Delhi/Thimphu, Ankara/Baghdad, La Paz/Brasilia, and Paris/Brasilia if you count French Guiana as part of France. But I can't find any difference bigger than 13.5 degrees. La Paz is so high up I thought it would win but Brasilia isn't quite as hot as Khartoum so the difference is only 12.25 degrees they I was figuring (it's a bit complicated as La Paz has different averages depending on how high up you are and where in the city you are measuring, but I tried to be fair and average all the data together). I also considered Moscow/Beijing, Rabat/Nouakchott, and Washington/Mexico but they weren't as close.

Thanks for all your feedback and for commenting my quiz; I would have probably missed your answers otherwise! Here's a couple of things I thought after reading your messages: - to add more answers you could perhaps have farthest/closest capitals for each continent - closest by country size: actually I meant something else but I certainly didn't choose the right wording. I meant that you take the distance between the capital cities and divide it by the sum of the areas of the two countries (perhaps you should actually square root it since you're comparing an area to a distance) and see what the maximum/minimum values are. I guess this would be won by Kinshasa/Brazzaville

oh, poop.... I don't know why I missed this before, but actually French Guiana touches Suriname, the capital of which, Paramaribo, is significantly hotter than Brasilia. There is actually a 14.6 degree C difference between the average annual temperature in Paris and that of Paramaribo... which of course means that if you count French Guiana as part of France then Paris/Paramaribo has a bigger temp difference than Addis and Khartoum.... but that seems a little too tricky, and I already used Paris for something else... I think I will just add a caveat to eliminate that as a potential answer.

Yeah, I know. That's why I added the caveat at the top. If Paris wasn't already part of the answer for the biggest GDP difference then I would have changed it to Paris/Paramaribo for greatest temperature difference. But I think it's better this way.

It works much better (for me) with the extra minute. Thanks. Also I'd read in a number of different places that Tegucigalpa is the world's most dangerous city. Does that not translate to total homicides?
+1
level 77
Sep 1, 2014
There are different ways to measure danger. I think I've seen 5 or 6 different lists online of the worlds' most dangerous cities or countries and they all pick different ones. They could look at the rate of homicide, or violent crime, or the death rate... but at any rate, what we're measuring here is total number of homicides in a pair of cities. Tegucigalpa's total, while very high, wasn't as high as the other two according to the data I looked at. If you find something more up-to-date it would be easy enough to fix.

Great idea for a quiz, though. You covered most of the main superlatives usually applied to countries/capitals. Perhaps some other categories of comparison could involve economics/wealth, oldest/newest capitals, official language(s) (of the country, of course, but applying it to the city), greatest difference in rainfall/other natural events, etc. Some of that data may be a little more difficult to find, but just wanted to leave some thoughts in case they could be useful to you!

Feb 9, 2017
Thanks! It's a bit hard figuring out how to assess the age of capital cities. If we're going by the date that the city was originally settled or established then almost certainly the pair would be Damascus, settled around 9000 BC, and either Amman (if you only count back as far as the city was continuously inhabited) or Ankara (if you ignore gaps in habitation). But it's complicated.

I added greatest different in precipitation (honorable mention to rainy Brasilia and Lima which gets almost 0, but nowhere near the difference between the top two answers that I found- however a reminder this is all based on independent research if you find an answer I overlooked please bring it up), and also added 2nd greatest distance so that Paris can take the top spot in that category, as well. I then upped the time limit to a very generous 6 minutes.

Very cool quiz. The only issue I have is the lack of accepting misspellings that are allowed in other quizzes. I guessed Brazilia (not Brasilia), Buenos Ares (not Aires) and Guatamala (not Guatamala City). I guess I should know how to spell those but if I mis type and its accepted elsewhere, here I feel like the answer is incorrect and move on.

Jul 1, 2018
Actually I think it was because of my repeated insistence that QuizMaster finally started accepted Guatemala for Guatemala City (and Kuwait, Panama, etc.), but "Guatamala" is spelled wrong. It's difficult anticipating everyone's incorrect spellings.

However, since authoring this quiz QM has updated the quiz editor with a feature that suggests type-ins. Given that capital cities are common answers on quizzes here, I assume those are all among the suggestions. I'll check it out and see if I can add the suggested type-ins so it's consistent with the rest of the site.
