Change, 2016 to 2022
CSO publishes yearly population estimates for counties and regions, not towns, so the trend is two censuses rather than a line; 2016 ages aren’t on 2022 boundaries, so there is no change by age.
For comparison, the median is +8% across Ireland’s towns and +6% across Co. Dublin’s towns.

What this data can and can’t tell you
- Against Co. Dublin’s towns and Ireland’s towns. Each comparison is its own median: over Co. Dublin’s towns of 2,500 or more and over 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.
- Neighbourhoods are sums of small areas. Neighbourhood figures are TownRatings sums of CSO Small Areas
