Compare other towns
iCastleknock sits in D15, Dalkey in A96. Each figure below is tagged with the geographic level it's actually measured at.
!Castleknock & Dalkey are city suburbs — its boundary follows the postal area (the Small Areas whose addresses carry the name), not an official settlement line, so it can run broader than the local core and the figures cover that wider postal patch.

Liveability & safety● AREA · D15 / A96
Wider-area figures, not the town. Quality of life & rank are for the whole Eircode area each town sits in (CastleknockD15, DalkeyA96); safety & crime are the DMR West Garda division.
Quality of Life
66/100
66/100

Quality of Life is the equal-weighted average of these seven 0–100 dimensions, scored for the whole Eircode routing area (D15 / A96) 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.

Castleknock Affluent+6.8
← more deprivednational avg · 0more affluent →
Spread across the town: Blanchardstown-coolmine -7 (least affluent) → Castleknock-park +10 (most affluent). It straddles the national average.
Dalkey Affluent+6.4
← more deprivednational avg · 0more affluent →
Spread across the town: Dalkey-coliemore +3 (least affluent) → Mansion House B +17 (most affluent). Even its least-affluent neighbourhood is above 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 West) — 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 22 CSO Small Areas.
