What is the size of Yemen? (2024)

I think a more important question is whether Yemen still exists as as single coherent political entity with the same borders as seen on ANY of those maps, which given the present situation, it clearly does not.

and here: https://yemen.liveuamap.com/

looks very much like the old north and south yemen borders doesn't it?

this was posted on 27. of november 2024. on the 3rd of december someone found a correct looking number in a yemen government document which was published in 2005 and updated wikipedia. so at least the country itself was not under any illusion of being bigger than they actually are.

Ah I'm glad. That's much better than the solution I had in mind of using the sand from the desert to expand the land into the sea to add extra 100k km of land area, to hide all this embarrassment under the rug.

That would have to be a pretty big rug. I actually know some rug merchants in New York who are having a going-out-of-business sale who might be able to help.

The author was one of the people involved in the wikipedia discussion

They knew the figure was wrong but needed a document with the correct figure they could reference.

i figured there was some connection, but i didn't expect the author to be involved because i would have expected that they update the article and mention that they found a document and fixed wikipedia.

What I wonder is why anyone noticed this in the first place. Who saw the size of the country in Wikipedia and thought, “really? Let me trace that in Google maps, just to be sure…”

Something about eyeballs and all bugs being shallow...

I actually measured the size of (parts of) Yemen on maps a week or two ago, trying to figure out the population density of the Houthi-controlled areas, which contain the majority (~70-80%, hard to say exactly as the population distribution has been changing rapidly in the past decade) of Yemen's population in about 1/3 of it's land.

This reminds me of what Deming used to say: there is no correct value for any measurement, there are only the outcomes of methods chosen to measure something.

I did not expect this to just be a simple mistake, especially one that's been around for decades. Makes you wonder what other kind of basic facts are wrong.

In the age of satellites, computers, Google maps and the like you would think a mistake like this would be impossible to persist for so long.

These kinds of issues have existed since the first human started recording what they owned, and will probably continue plaguing us until the last one dies.

No - only till the second last one dies.

A bunch of countries are suspected of undercounting their population because so many people are living "off the grid" or deliberately overcounting to get more funding. Probably some of the cases are real and some are just conspiracy theories.

Imagine how much of published science is statistically significant only due to clerical errors and mistakes in calculation...

(See e.g. The misreporting of statistical results in psychology journals; Bakker, Wicherts; Behaviour Research Methods; 2011.)

I remember hearing from a Yemeni American in the late 90s that the border with Saudi was not defined (mentioned in the article). I wonder if this could be explained more simply that a few sources didn't bother to update this over time due to the ambiguity, they just carried over what had been published before.

A casual review of the satellite view of the border with Saudi Arabia shows that much of it is desolate uninhabited sand dunes, so it's not like there's border markers such as the US/Canada have. Or likely an accurate survey (you'd need high precision GNSS equipment and something that can traverse serious sand dunes as a vehicle, because no fixed markers and traditional surveying methods have any chance of success there).

Historically, borders in inhospitable regions where the government cannot project power used to be vague.

Early Medieval European kingdoms usually had border forests, sometimes quite deep (50-100 km), where one end of the forest was definitely Bohemian and the other end definitely Saxon or Austrian, but the exact demarcation within it bothered no one.

There were only two kinds of people crossing them: invading armies and long-distance traders on very few walkable paths. The latter would be taxed prior to entering the city markets, not on the border. The former would be interested in sieging strongholds deeper in the enemy territory, not in taking a slice of wooded territory on the border.

Great article. Somehow, this gives me hope that curiosity can still be rewarded in this age of information at our fingertips.

Although I do hope too that people don't lose their sense of meaning and curiosity too much, it's worth keeping in mind that this article was published in 2024 which was a very different world from now. Curiosity requires energy, and it'll be hard for a creature relying on energy for survival to justify using their own energy for some activity when there's a more energy-efficient way to reach a specific goal. But just like going to the gym makes your body healthier despite the fact that this requires energy, thinking on your own will be increasingly important for maintaining a healthy mind and the sense of self.

Great article. I wonder if the sum of the land areas of all countries on earth matches the global size of emerged land? Or are there other similar errors?

This is why you read the code, not the documentation.

This happens more frequently then one imagines. Quite a few things fail to start from scratch and instead rely on compounded errors over time. Projections, budgets, etc., are sometimes based on stale information.

Always picture it larger, but it's roughly the size of France. Makes you wonder about logistical challenges there.

I suppose it's not worth checking whether Google maps areas are measured using spherical geometry?

You could check, but it would be quite shocking if they weren’t.

A 100-year-old data bug propagated through the entire knowledge base because nobody bothered to add a test.

This makes me wonder, what's the difference between the 2D area and the 3D topographic surface area? Is the latter even ever measured?

3D topographic surface area has the "coastline problem" where the more precisely you measure it, the more it grows.

2D area is stable under increasing measurement precision.

Human civilisation is built on such lies ;)

I wonder if you sum every countries claimed size, how far off it is from the actual total land on Earth.

Well, this is a pretty perfect usecase for AI (although it's also easy to just get shapefiles from NE and do it yourself, obviously).

Interestingly all of UAE, Yemen and Saudi Arabia have significant discrepancies between the World Factbook and their shapefiles (in every case overestimating), probably all related to not having had a demarcated border in the Rub Al Khali.

A quick lazy calculation (including adding in Antartica) the countries totals came up ~2,000,000km2 short. I don't care enough to dive deeper, but if no one is claiming that land I'll happily take it.

This is such a nice article!

It's an AI hallucination in slow motion.

15 Yemen Road, Yemen

I will write you every day.

(I suppose people downvoting this don’t know the reference. Way to make us feel old :) )

HN eschews pop culture references, the down voters are almost certain to include those that are aware of US sitcoms.

a nice article!

Ye man, this is crazy
