iCastleknock sits in D15, Monkstown in A94. Each figure below is tagged with the geographic level it’s actually measured at. The town ahead on a row is the one in green. Scores and percentages are charted against a true 0 to 100 scale; every other row is charted against the larger of the two towns, so the bars compare but don’t imply a ceiling.
!Castleknock & Monkstown 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.

Outlines are each town’s CSO Small Areas — the exact footprint every figure is measured over.

Liveability & safety

AREA · D15 / A94

Wider-area figures, not the town. Quality of life & rank are for the whole Eircode area each town sits in (CastleknockD15, MonkstownA94); safety & crime are the DMR West Garda division.

66/100
Quality of Life
72/100
Monkstown leads

Quality of Life is the equal-weighted average of these seven 0–100 dimensions, scored for the whole Eircode routing area (D15 / A94) 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

How accurate is this, and at what level?

TOWN
Prices, amenities and commute are exact and 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.

ED
Affluence, profile and tenure are Electoral-Division level.

Published per Electoral Division and averaged across the town’s EDs, with a range where the town spans several.

AREA
Liveability and safety are wider-area, not the town.

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

Population growth isn’t shown: the 2016 and 2022 censuses don’t use the same Small Areas, and the areas that were re-cut are the ones that grew, so a like-for-like comparison understates growth badly. Rent and yield are still too sparse to show per town. Built from 20 CSO Small Areas.
