Sweden just barely doesn’t make the cut by several hundred thousand. Thailand missed out by about 6 million.

Thailand borders Myanmar and Malaysia, combine those two alone and you well exceed Thailand.

Well no, because Thailand also borders Cambodia and Laos. And in any case the figure of 6 million is way off - Myanmar and Malaysia alone would surpass the population of Thailand by a lot more than that.

Everyone who studies math long enough discovers that everything is maths, and all maths is sets. Talking about sets and logic here makes the previous statement technically true.

Haiti was kind of surprising for me, I always figured the DR would have more people just because it's the larger country in area.

Three of these countries only have one neighbour - South Korea only borders North Korea, UK only borders Ireland and Haiti only borders the Dominican Republic. While the UK has many times the population of Ireland and South Korea is twice as populous as it's northern counterpart, Haiti is only slightly more populated than the Dominican Republic.

Sweden and the USA only border two other countries. The US has twice the population of Canada + Mexico, while Sweden narrowly outnumbers Norway and Finland's combined populations.

Indonesia borders three other countries( Malaysia, East Timor and PNG) and outnumbers them five times over.

Nigeria borders four other countries( Benin, Niger, Chad and Cameroon) and outnumbers them about 3 to 1.

South Africa borders six other countries( Lesotho, Eswatini, Mozambique, Zimbabwe, Botswana and Namibia.) and outnumbers them by about 5 million people.

Or if you count Gibraltar, UK has two borders, and still has 15 million more than its neighbors combined.

The only reason I could see for Brazil not meeting the criteria is because it borders France (via French Guyana). Otherwise, Brazil definitely should be on the list

What is the picture of? It has to be a road in the US, but I can't place the mountain. best guess is somewhere in Alaska or Washington state given the heavy glaciation on the mountain there, but I can't think of any roads that look like that in either state. Looks kind of like the Icefields Parkway in Alberta.

Edit: definitely the Icefields Parkway, taken from just north of the Athabasca Glacier, that is definitely Mount Athabasca in the back there. Surprised it isn't a picture from a country on the list.

India most populous country in the world. How is it not a valid answer?

"countries whose population is greater than that of every one of their neighbors combined"

India population is 1.429 billion

All its neighbours combined:

Afghanistan population is 42 million

Pakistan population is 241 million

China population is 1.411 billion

Bhutan population is 1 million

Nepal population is 32 million

Myanmar population is 55 million

Bangladesh population is 173 million

So the population of every one of India's neighours combined is 1.955 billion.

Is India's population greater than that of every one of their neighbors combined?

NO

My guess is that it's so narrow, there's a decent amount of room for error due to natural fluctuations. Just a guess

LegoBuilderOne

Yes, it should. Yemen's population is 4-5 million more than Saudi Arabia's and Oman's.

What's the source for this? Citypop has Saudi Arabia at 35.3 mil and Yemen at 31.9 mil (though the estimate for Yemen is two years older). Wikipedia has Yemen at 32.7 mil and Saudi Arabia at 32.2 mil--smaller, but definitely not enough smaller that Yemen would still beat it PLUS Oman.

I'm not trying to argue these sources are definitive; I just want to know what source you (and apparently the quiz owner) are using that says that Yemen has more people than Saudi Arabia + Oman, because by these two sources the answer is "No" and it's not particularly close.

We use the same source for all our country population quizzes:

https://www.jetpunk.com/data/population/countries-by-population

It's based on the 2024 Edition of World Population Prospects by the UN.

Wouldn't it be better to use an official source and not the UN's guess? Yemen says it's 32 million, the UN says 40. Same for a lot of other countries. The US is off by 11 million.
Quizmaster

No. We can't use the official source for every country separately. That's madness.

First of all, different countries use different methodologies. Is the entire population counted, or just citizens?

Secondly, many (or most) countries don't even conduct regular censuses. For example, the last census in Nigeria was in 2006. Do you think that Yemen, which is currently in the midst of a civil war, is doing an accurate census? C'mon.

Thirdly, the UN data IS based on official sources but corrects for the issues I mentioned above.

There are lots of problems with the UN data too. But it's by far the best source for comparisons between countries. That's why I built an entire dashboard based on it.

In 2023, Yemen's Ministry of Health estimated its population at 32.7 million. In 2024, the World Bank estimated the population at 40.5 million. Given the decade-long civil war, it's hard to believe either number is accurate. Saudi Arabia has a population of 35 million in 2024 according to the World Bank. Using World Bank numbers, its accurate to include Yemen but using Wikipedia (the 2023 number) its not.

Yemen having a full Oman more people than the KSA is crazy, given their obvious size difference. You do wonder how long that'll last with all the Indians the latter's bringing in... but maybe Yemen's birth rate is enough to keep pace, Idk
