The marker shows the atlas location. Small countries may be too small for an outline at this scale. Map boundaries are illustrative.
People, languages and currency
The World Bank records 6,484,437 people for Republic of the Congo in 2025. This is the latest non-empty annual observation in Roam’s committed 2020–2025 download, rather than a live population counter. Dividing that population by the source area gives approximately 19 people per square kilometre. This calculated average does not describe how evenly people are distributed.
The language entries in the source are French, Kikongo, and Lingala. They describe the dataset’s listed languages, not every language spoken by residents. The currency listed for this date is Central African CFA Franc (XAF). Currency assignments are selected from Unicode CLDR’s date ranges for 23 October 2026; the three-letter codes identify currencies, not countries.
