Flag of Sudan
The flag of Sudan is composed of three equal horizontal bands of red, white and black, with a green isosceles triangle superimposed on the hoist side. The green triangle spans about two-fifth the width of the field with its base on the hoist end.
Where it is
Sudan is grouped in Northern Africa, within Roam’s Africa region. Its land-border list includes 7 countries in this atlas: Central African Republic, Chad, Egypt, Eritrea, Ethiopia, Libya, South Sudan. The source classifies it as not landlocked.
Sudan has a recorded area of 1,886,068 square kilometres. Among the 6 countries assigned to Northern Africa in this dataset, it ranks 2 by area, from largest to smallest. Algeria is immediately above it in that ordering, at 2,381,741 km². Libya is immediately below it, at 1,759,540 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 51,662,147 people for 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 27 people per square kilometre. This calculated average does not describe how evenly people are distributed.
The language entries in the source are Arabic and English. They describe the dataset’s listed languages, not every language spoken by residents. The currency listed for this date is Sudanese Pound (SDG). Currency assignments are selected from Unicode CLDR’s date ranges for 23 October 2026; the three-letter codes identify currencies, not countries.
