Limited evidenceUpdated 24 h ago

Strong structural fit for the selected priorities (77/100).

Evidence coverage is limited; the ranking may move with new observations.

AlternativeAndorra

Main uncertaintyThe lead over Andorra is small. Some requested evidence is unavailable; the score is rescaled over the evidence that exists.
