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!

to 'test' the method you can for example see if it found 24 for Italy like wikipedia says - https://it.wikipedia.org/wiki/Isole_italiane_per_superficie

The title is "countries with the most islands" so why the 10 square km cut-off? According to this definition, the Maldives (with about 1,190 islands) has 0 islands. There can be difficulties determining the difference between islands and sandbars, for example, but the current cut-off is arbitrarily weird.

This comment is a little annoying. Read my methodology (the first comment), and then realize how much work it took to create this quiz. Better data doesn't exist.

I don't doubt that it was complicated and a lot of work, so thanks for doing that. What I don't understand is the 10 square km filter. What was your thinking there?

tshalla has a point. I was thinking many more of the Caribbean and Oceania countries would make this list - when in fact next to none did. Seems strange to only include islands of an arbitrary size. Still enjoyed the quiz, don't get me wrong! I just wonder how the designation of 10 km was decided.

There has to be a cutoff somewhere. Otherwise, there could be millions of islands. Maybe even billions in areas where the land is near sea level. But the reason I chose 10 square kilometers is that the map I used included most islands of that size, but not necessarily smaller islands.

I also doubt that countries of Oceania or the Caribbean would appear on this quiz - no matter what the cutoff.

and yes, the smaller you make the cutoff, generally speaking, the bigger the numbers would get for all countries. It's not like Canada has tons of big islands but no smaller ones...

I too was stunned that Croatia wasn't up there, but yeah – I guess a lot of the islands fell under the cutoff. I never considered 10 sq km as being very large, but now that I think about it, it kinda is :-)

If you treat Cook Islands and Niue as territories of NZ, rather than countries, then New Zealand makes this list with 39 islands! There are 32 in NZ proper (https://en.wikipedia.org/wiki/List_of_islands_of_New_Zealand), another 6 in the Cook Islands (Rarotonga, Mangaia, Aitutaki, Atiu, Mauke and Mitiaro), plus the island of Niue itself.

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."

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

Impressed by Quizmasters Islands quiz, surfed the web for lists of countries with most islands. The Telegraph and some other sources have recent lists. You can naturally ask what is the definition of an island? You are welcome to see the lists I used in "Top 10 Countries With the Most Islands"
