Which of these countries has the most islands?

One of earth's northernmost countries, Sweden has 221,831 counted islands, about 24,000 of which are open to the public through the country's Right of Public Access policy, which allows anyone to hike through lush forests and fields, and forage for berries or mushrooms without asking landowner permission, so long as they show respect for the natural environment and private property. Though Sweden is the country with the most islands in the world, less than 1,000 of them are inhabited.
