Where it is
Bulgaria is grouped in Southeast Europe, within Roam’s Europe region. Its land-border list includes 5 countries in this atlas: Greece, North Macedonia, Romania, Serbia, Türkiye. The source classifies it as not landlocked.
Bulgaria has a recorded area of 110,879 square kilometres. Among the 8 countries assigned to Southeast Europe in this dataset, it ranks 2 by area, from largest to smallest. Romania is immediately above it in that ordering, at 238,391 km². Serbia is immediately below it, at 77,589 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 6,433,302 people for Bulgaria 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 58 people per square kilometre. This calculated average does not describe how evenly people are distributed.
The language entries in the source are Bulgarian. They describe the dataset’s listed languages, not every language spoken by residents. The currency listed for this date is Euro (EUR). Currency assignments are selected from Unicode CLDR’s date ranges for 23 October 2026; the three-letter codes identify currencies, not countries.
