What this data can and can’t tell you
- Against Co. Monaghan’s towns and Ireland’s towns. Co. Monaghan has fewer than five towns of 2,500 or more, so its figure is the median of its towns of 1,000 or more; the national figure is the median of the Irish towns of 2,500 or more (city totals left out). Percentiles are within Ireland only.
- The earlier population is an estimate. Towns had no official 2016 count on today’s boundaries, so the 2016 figure is CSO’s electoral-division count shared out by where people lived in 2022: read a small town in a large rural division loosely.
- What these tables don’t give. The small-area tables give no year of arrival and no hours of care, and a town’s electoral divisions run past its edge, so the page doesn’t split a town into named areas (a city lists its neighbourhoods).
- The census’s own words. Born abroad, citizenship, ethnic or cultural background and religion are CSO’s questions and categories; the page compares them with other towns and never labels a town by them.
