+This module defines a dictionary of nationalities and their corresponding

+
+The `NATIONALITIES` dictionary maps each nationality to its respective
+alpha-2 country code, where the keys are nationality names (in English)
+and the values are ISO 3166-1 alpha-2 codes.
+
+Example usage:
+    - "Afghan" -> "AF"
+    - "Åland Island" -> "AX"
+
+The dictionary can be used for looking up the alpha-2 code based on a
+given nationality name.
