What these terms mean
- Census year
- A year CSO actually carried out a full population count — 2011, 2016 and 2022 for this series. Not published for any other year. Source
- Local authority
- The 31 city and county councils — the same administrative areas this site's other per-council datasets (planning permissions, tender awards, local authority budgets) are published for.
Before you use these figures
- Not available for this area: No figure is published at or above Mayo.
- Census years only, not a continuous series: This is CSO's actual Census of Population count, taken once every five years (2011, 2016, 2022) — not a modelled annual estimate. A figure from a year between censuses is not published here at all; the 'latest' point can be several years old.
- Cork City and Cork County split only from 2022: CSO's own combined county/city census table publishes one figure for Cork City and Cork County together for 2011 and 2016 — the city boundary was extended in 2019, so a clean pre/post split back to a comparable historical baseline does not exist in that table. A separate CSO table (F1010) publishes a real per-council split from 2022 onward, used here for that year; 2011 and 2016 are not split.
- Latest figure: 2022 — 4 years old: This dataset is published annually and the publisher hasn't released anything newer. Nothing is missing from this page.
