A Surprising Record Holder
When people imagine a country covered in islands, they often picture a tropical nation. But the country with the most islands in the world is Sweden, in northern Europe. Sweden has an estimated 267,570 islands, far more than any other country.
So Many Islands, So Few People
The truly remarkable thing about Swedens islands is how few of them anyone actually lives on. Out of more than a quarter of a million islands, only a tiny fraction, well under one percent, are inhabited. The vast majority are small, rocky, uninhabited outcrops scattered through the cold waters of the Baltic Sea and along Swedens long coastline.
Why Counting Islands Is Tricky
Part of the reason Swedens number is so high comes down to how an island is defined. Sweden counts even very small landmasses surrounded by water as islands, so the total climbs into the hundreds of thousands. Other countries use stricter definitions, which is one reason island counts vary so much from source to source. Swedens islands are also still slowly changing, as the land itself gently rises out of the sea over time.
