Background Notes

Open in Excel:


It should be noted that for 2017 onwards the number of births as per the Irish Babies' Names Tables are on the basis of those births registered in 2017 (from 01\01\2017 to 31\12\2017 inclusive) rather than the number of births recorded in the summary of the 4 quarters of the relevant year.

These results are based on an analysis of the first names recorded on birth returns for registration and vital statistics, begun by the CSO in 1998. All birth notifications in 2017 included the baby’s first name when the statistical return was sent to the CSO.  In addition, data on all forenames for years (1964 to 2017 inclusive) with 3 or more occurrences is now available on our statbank. VSA05 and VSA12 refer -  classifying all boys and girls names respectively with 3 or more occurrences, by year, number and rank.

Information recorded

Only the first name was used for this analysis. Babies’ additional forenames were not extracted by the CSO. 

Spellings and variants

Different spellings of a name have been treated as separate names. For example, while there were 120 boys named Eoin, another 110 had the alternate spelling Eoghan. Similarly, if you combine the number of girls named Anna (293) and Annie (89) then it becomes the 3rd most popular name for girls in 2017. Variants of names and abbreviations have also been treated as separate names. For example, Jack, Sean and John account for 1,548 boys. These were counted as separate names and rank first, fifth and twenty-eight respectively. If treated as variants of John, it would rank as the most popular boys' name.  Names containing accents have been recorded without those accents e.g. Seán was recorded as Sean.


Names of equal rank have been placed in alphabetical order in Table 1.
