Hillsborough 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 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. 1,887 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.
