Andorra
Andorra is one of only six of the world's independent countries that do not have Scouting. The population is sufficiently large to sustain Scouting, but the Scout association of the tiny enclave in the Pyrenees, Scouts d'Andorra, has been dormant since the 1980s and at present there is no Scouting movement. Likely it was spearheaded by a single dedicated local volunteer no longer involved, or at most a few who lost impetus. At least one group was known to be sponsored by Mare Janer Catholic School, known then as Mare Janer College.
Interestingly, the tiny principality has issued Scout Centenary stamps for the 2007 celebration, through both French and Spanish posts.
