Sion Mills in context

The population, measured on a real boundary
| What you mean | Population | Source |
|---|---|---|
| Sion Mills settlement NISRA's settlement boundary: the built-up Sion Mills | 1,970 | Census 2021 |
| Sion Mills (GeoNames record) the figure in this page's heading; boundary unstated | 2,212 | 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. 888 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.
