Liveability & safety● AREA · D11 / D15
Wider-area figures, not the town. Quality of life & rank are for the whole Eircode area each town sits in (BallymunD11, CastleknockD15); safety & crime are the DMR North Garda division.
Quality of Life
58/100
66/100

Quality of Life is the equal-weighted average of these seven 0–100 dimensions, scored for the whole Eircode routing area (D11 / D15) from official data — Garda crime, CSO income & census, OPW flood, EPA water, and transport/healthcare/broadband coverage. Refreshed quarterly. The dashed line is each town's overall score (that average) — dimensions to its right beat the average, to its left fall short. Two towns can share a score with a very different mix.

Affluence range

Pobal HP deprivation index — published per Electoral Division, so the spread shows the town's poorest to richest ED. A town that is a single ED shows one mark, no range.

Ballymun Disadvantaged-8.2
← more deprivednational avg · 0more affluent →
Spread across the town: Ballymun D -21 (least affluent) → Ballymun E +3 (most affluent). It straddles the national average.
Castleknock Affluent+6.8

Spread across the town: Blanchardstown-coolmine -7 (least affluent) → Castleknock-park +10 (most affluent). It straddles the national average.

How accurate is this, and at what level?

● TOWN
Prices, amenities & commute — exact, town-specific.

Prices come from individual PPR sales inside the town's Small-Area boundary; schools, GPs, transport, gyms and parks are counted the same way; commute is routed from the town centre. The figures the routing-key area page can't give you.

● ED
Affluence, profile & tenure — Electoral-Division level.

Pobal HP, third-level, class, unemployment, tenure are published per Electoral Division and averaged across the town's EDs — a range where the town spans several EDs (see the bar above).

● AREA
Liveability & safety — wider-area, not the town.

Quality of life and rank are per Eircode routing key; safety & crime are the Garda division (DMR North) — coarser than a town, so two towns in the same county read the same.

Population & growth are loaded for ~7 counties so far (not Leinster yet); rent & yield are too sparse per town. Tap Schools or Affluence to drill in. Built from 15 CSO Small Areas.

The verdict

Castleknock is the stronger town on the data — it leads on 3 of the 7 dimensions to Ballymun’s 2, with 2 level: affluence, education levels and public transport. Ballymun leads on safety and affordability.

Higher is better on every spoke — affluence, education, amenity density, transport, safety, affordability and nearest-city access, scored head-to-head.
