Thanks to all the people who pointed out errors in the previous version. This version uses a better methodology. I started with this geospatial data. Then I wrote a program to count the islands. This time I wrote additional code to filter out islands less than 10 square km in size. Finally, I checked Wikipedia to see if there were any missing islands. This increased the # of islands in Greece, although certain countries might still be missing islands. I think this quiz is mostly accurate now!

Finland has thousands of islands but only small, with 759 islands over 1 sq.Km in size. not a very large country but great in islands and some beauties too.

Quite right, here is a quote from Wikipedia about the archipelago Sea:

"If the number of smallest uninhabitable rocks and skerries is accounted, 50,000 is probably a good estimate. In comparison, the number of islands in Canadian Arctic Archipelago is 36,563. Indonesia has 17,508 islands, and The Philippines have 7,107 islands."

According to your comments, either you cant read, or well something else is going on, but dont want to be too rude.

when someone says "islands smaller than 10km2 are excluded" and you accuse them of saying that those arent islands, something goes very wrong in your logic.

In an amusement park when it says girls shorter than 1.20m arent allowed in this ride. Would you complain to the owner of the park and accuse him of claiming that girls under 1.20m arent girls? sounds preposterous right?

(PS I changed it to girls instead of kids, because well it is not universally agreed upon what ages you are considered a kid)

+4

I think tshalla's logic is that the title of the quiz just says islands, but then only counts islands of a certain criteria. It would be like a quiz saying "countries with most girls", but only counting girls over a certain height, and then someone saying "are you saying shorter girls aren't girls!?".

Personally, I can see the logical jump. (but I don't think there is anything wrong with the title or methodology)

Again perhaps try reading the comments before commenting. People just might be proud of their countries and want to share that theirs have a lot of island eventhough not enough above 10km2 to make it to the list.

I could add, my country has about 45 (more like 55 if you count the ones that used to be islands but are now connected with dams for instances)

Here is some information you might want to take into consideration for your next version of this quiz:

6.000 islands

Greece has 6.000 islands in total, scattered in the Aegean and Ionian Seas, of which only 227 are inhabited. They take up 7,500 km of the country's total 16,000 km coastline. Spreading in two main seas, the Aegean and the Ionian Sea, the Greek islands are divided into smaller groups.

Therefore, even if you were to use only the 227 islands that are INHABITED -- it would put Greece up near the top.

Thank you

Really mad at forgetting Greece. Was thinking what European countries has a lot of islands and thought Croatia, France, Denmark, UK, Italy, Norway and Finland. Not sure why Greece didn't come to mind. anyway. 19/20 is more than I expected to get. I think being Australian helped me think about the Oceanic countries such as Solomon Islands which many missed.

I allways have the same problem greece comes to mind last or not at all in quizes. This time it came to me, but as the last answers I was sure about, after that it was guess work.

I guess for me it might be that they dont totally feel part of western europe ( as much as the others) but also not really part of eastern europe. I have no other explanation. It keeps happening time and time again.

Maybe it is allready done, but indeed an idea for a similar quiz to do this but then with inhabited islands?. Or just the named ones, surely that data is out there somewhere, I know it is for my country atleast.

There are more than 41 islands in Finland that are at least 10 square kilometres in size. According to Finnish Wikipedia, there are 67 islands located in the sea area and 59 islands in the inland water area. That makes 126 islands in total.

Nice effort but the poor resolution of the data kind of makes the quiz pointless. My country Sweden for example has almost 100 islands with an area over 10km2. Its not even on the list. I guess the same errors is expected for other countries.

if you take the total area of Sweden's islands and divide by the crazy high number of islands they claim the average size would be something like 2 football fields. Much less than 10 square km. Have you got a source for that 100 figure?

Yes, the swedish wiki page listes the biggest 50. The smallest of them is 22km2.

https://sv.m.wikipedia.org/wiki/Lista_%C3%B6ver_%C3%B6ar_i_Sverige

Most swedish islands are small. But many are big.

Also, what kind of logic is that. Do you think all islands are the same size? most are may be half a football field or smaller. thousands are 5-10 football fields. And with som many islands, a large number of the are bound to be larger than 10km2. The once mentioned in the wikipedia are just some of them.

Norrbotten province (the northernmost province) alone has 17 030 islands with the largest inhabited one "Pitholmen" being 81km2. And all islands in norrbotten is growing fast as the land rises. Some islands might become peninsulars in a few hundred years. But for now norrbotten county has more islands than the enture USA.

India seems to be missing on this list. From my own research based on this article, I can safely say that India has more than 40 islands of area 10 sq km or larger. I have manually counted the minimum number of islands which could prove that India belongs in the top 20.

The exact number of islands could be much larger, since I didn't check the area of all the islands in the list. The majority (~35) of such islands are found in Andaman and Nicobar Islands. I know this would be hard, but please update the quiz with the inclusion of India in the next update.
