Castlewellan in context
Distances are straight-line from the settlement's recorded coordinates. The 10 km figure sums the recorded places within that radius, so it describes how built-up the surroundings are rather than people per square kilometre.
The population, measured on a real boundary
| What you mean | Population | Source |
|---|---|---|
| Castlewellan settlement NISRA's settlement boundary: the built-up Castlewellan | 2,822 | Census 2021 |
| Castlewellan (GeoNames record) the figure in this page's heading; boundary unstated | 2,499 | GeoNames |
The census figure is NISRA's Census 2021 count of usual residents inside the settlement's development limit: a boundary drawn in 2014–15 holding 2021 people, so growth at the edges since then sits outside it. 1,101 households. Where the rows disagree, quote the census. Northern Ireland's other layers wait on data that is either licensed (postcodes) or published only at district level (crime), and those absences are deliberate.
