Flag of South Sudan
The flag of South Sudan is composed of three equal horizontal bands of black, red with white top and bottom edges, and green. A blue equilateral triangle which spans about two-fifth the width of the field is superimposed on the hoist side with its base on the hoist end of the field. At the center of this triangle is a five-pointed yellow star.
Where it is
South Sudan is grouped in Middle Africa, within Roam’s Africa region. Its land-border list includes 6 countries in this atlas: Central African Republic, Democratic Republic of the Congo, Ethiopia, Kenya, Sudan, Uganda. It is landlocked.
South Sudan has a recorded area of 619,745 square kilometres. Among the 10 countries assigned to Middle Africa in this dataset, it ranks 5 by area, from largest to smallest. Central African Republic is immediately above it in that ordering, at 622,984 km². Cameroon is immediately below it, at 475,442 km². This comparison uses the source’s area figures and subregions, not a ranking of all territories.
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 12,188,788 people for South Sudan 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 20 people per square kilometre. This calculated average does not describe how evenly people are distributed.
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 South Sudanese Pound (SSP). Currency assignments are selected from Unicode CLDR’s date ranges for 23 October 2026; the three-letter codes identify currencies, not countries.
