Where it is
Saint Lucia is grouped in Caribbean, within Roam’s North America region. No land neighbours are listed in the source. The source classifies it as not landlocked.
Saint Lucia has a recorded area of 616 square kilometres. Among the 13 countries assigned to Caribbean in this dataset, it ranks 8 by area, from largest to smallest. Dominica is immediately above it in that ordering, at 751 km². Antigua and Barbuda is immediately below it, at 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 180,149 people for Saint Lucia 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 292 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 East Caribbean Dollar (XCD). Currency assignments are selected from Unicode CLDR’s date ranges for 23 October 2026; the three-letter codes identify currencies, not countries.
