Before you use these figures
- 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 not published separately: CSO publishes one combined population figure for Cork City and Cork County across all three census years — the city boundary was extended in 2019, so a clean pre/post split back to a comparable historical baseline does not exist. No population figure is shown for either council rather than estimating a split CSO itself declined to publish.
- 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.
