Sarah Mooney The Central Statistics Office (CSO) has revealed the most popular Irish baby names in 2021, with several new entries to the top 100 slots. For boys, Jack remains the most popular name registered last year, while for girls, Fiadh has ousted Grace to take the most popular slot. Jack was followed by Noah, James, Conor and Rían as the five most popular names for boys, while Fiadh was followed by Grace, Emily, Sophie and Éabha for girls. Looking back 50 years ago, in 1971, the most popular names were John and Mary. CSO statistician Gerard Doolan said baby name trends have seen significant change over the last half-century in Ireland, with not one of the top five names for girls last year appearing in the top 100 names a half-century earlier. “Jack has retained the top spot as the most popular baby boys’ name in 2021, a position it has held since 2007 except for 2016, when James was the most popular choice,” he said. “Looking back 50 years ago to 1971, John, Michael, Patrick, David and James were the names most favoured by parents of newborn baby boys. There were 198 male newborns named John in 2021, compared with 2,654 in 1971. “Interestingly, not one of the top five names for girls in 2021 appeared in the top 100 names a half century earlier. Mary, Catherine, Margaret, Fiona and Sinead were the most popular names for baby daughters in 1971, with 1,907 baby girls named Mary in that year.” Mr Doolan said Grace, Emily and Sophie have been "permanent fixtures" in the top five names for baby girls every year since 2016.

New entrants to top 100

With Fiadh taking the top slot for girls for the first time last year, there were 424 babies given the name, representing 22.2 per cent of the number given the name Mary in 1971. “Fiadh has improved her ranking every year since 2009 when it was the 488th most popular girls name. In recent years, Fiadh has continued to increase in popularity, ranking 3rd in 2019, to 2nd in 2020 before now taking the top ranking in 2021," Mr Doolan said. “Over the years, girls are given a wider variety of names than boys with 4,741 girls’ names registered in 2021 compared to 3,863 boys’ names. “After only one new entrant into the top 100 names for boys in 2020, there were 10 new entrants for 2021. The names Teddy, Daithí, Páidí, Jaxon, Brody, Ted, Hunter, Tadgh, Tiernan and Arlo all featured in the top 100 boys’ names for 2021. “The boys’ name with the most growth in popularity in terms of rank between 2020 and 2021 was Ted, jumping 49 places from 139th place to 90th place. “There were three new entrants to the top 100 for girls: Indie, Ayla and Lottie. Croía is the girls' name that has grown the most in popularity in 2021, jumping 43 places, rising from 95th place in 2020 to 52nd in 2021.” The CSO said some less common names for boys included Rome, Kobie, Thady, Saul and Eanna. Less popular girls’ names included Sky, Princess, Valerie, Ophelia and Noelle.
