About this profile
This page is one of 250 country profiles on MapVista. The structured facts are sourced from open datasets that aggregate official records — see our methodology for the full list of sources and how we handle disputes, succession, and edge cases. The narrative paragraphs are written to give context to the numbers, but the figures themselves are not invented; if a value is missing it is shown as a dash rather than a guess.
If you spot an out-of-date figure or a misclassification, please reach us via the contact page. We refresh the underlying dataset regularly and corrections are applied at the next rebuild.
