Most Landlocked Countries by First Level Subdivision Borders
We counted how many land borders between first level subdivisions you have to cross to reach the ocean from every first level subdivision. Can you name the 20 countries which have the highest average of borders you have to cross?
LLL = Level of LandLockedness
The Caspian Sea is a lake and thus not part of the ocean.
Two subdivisions are on islands in a lake and thus have no way of reaching the ocean. These have been counted as LLL 10.
Massive thanks to SaturnTheQuizzer for figuring out the levels of landlockedness!
This is not whether the country is landlocked or not. It is about the average landlockedness of each of the First Level Subdivisions of each country. While Slovenia and the DRC are indeed coastal (and have some Subdivisions with landlockedness level 0, i.e. coastal), they have more subdivisions that are so landlocked that the average is driven up. That is why they (barely) make the cut.
