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.

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 15 CSO Small Areas.

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