Irish public data, by county
StatsMapped

Religion: No religion for every Irish local authority, ranked from highest to lowest, from official public data.

Why the caveats matter

Every figure carries the publisher's own caveats. Where a statistic is published for a wider area than the one you clicked, or where the publisher itself flags it as unreliable, the page says so rather than quietly rounding it off.

Religion: No religion — every local authority ranked

These are raw counts, not rates -- a larger area ranks higher on this page mainly because it has more people, not necessarily a worse underlying rate.

Figures as of 2022, published by CSO Census of Population — Small Area Population Statistics (religion, ethnicity, travel to work, residence a year ago). Accessed 2026-09-21.

Usually resident population by religion, from Census 2016 and 2022 — Catholic, other religion, no religion, or not stated.

Before you use these figures

  • 2016 and 2022 figures cover different areas: Cork City Council's boundary was extended in 2019, taking in a large area previously part of Cork County. This series' 2016 figure covers the smaller, pre-2019 city; its 2022 figure covers the larger, post-2019 city. The change between them reflects the boundary redraw, not a real change in the population it describes — not a trend to compare year over year.
  • Census years only, not a continuous series: This is CSO's actual Census of Population count, taken once every five years (2016, 2022 for this breakdown) — not a modelled annual estimate. No figure is published for any year in between, and this will not update again until the next census.
  • Latest figure: 2022 — 4 years old: This dataset is published annual and the publisher hasn't released anything newer. Nothing is missing from this page.
