The language entries in the source are English. They describe the dataset’s listed languages, not every language spoken by residents. The currency listed for this date is US Dollar (USD). Currency assignments are selected from Unicode CLDR’s date ranges for 23 October 2026; the three-letter codes identify currencies, not countries.
