Amelia and Harper have become the new most popular names for baby girls born in the East Riding.
ONS figures show that 19 newborns were given the names Amelia or Harper last year – though this was six fewer than previous top ranker Olivia.
Meanwhile, 36 babies made George the top boys’ name in 2018 – four fewer than the year before.
The 619 babies who were called Muhammad across Yorkshire and The Humber meant it was the most popular boys’ name throughout the region, beating Oliver and George to top spot.
Olivia was the top Yorkshire and The Humber girls’ name – 393 newborns were handed the moniker by their parents, pushing it to the top of the list, ahead of Amelia and Isla.
Nationally, Oliver remained the most popular name for boys in England and Wales for the sixth year in a row, ahead of George and Harry.
The ONS data showed Grayson, Rowan and Tobias entered the top 100 names for boys for the first time in 2018.
Olivia topped the girls’ list for the third year in succession, with Amelia and Ava in second and third respectively.
Ada, Delilah, Ayla, Zoe, Margot and Felicity entered the top 100 names.
Arthur was the only new entry in the top 10 names for boys in 2018, in seventh, moving Jacob down to 11th.
Sophia and Grace, at eighth and 10th respectively, replaced Poppy and Lily in the top 10 names for girls.
Nick Stripe, from the ONS, said: “Oliver and Olivia remained the most popular baby names in 2018, although there are the first signs that Oliver’s six-year reign as the number one name for boys is under threat.
“Arthur surged into the top 10 boys’ names for the first time since the 1920s, and Ada jumped into the girls’ top 100 for the first time in a century too, both perhaps inspired by characters in the BBC TV drama Peaky Blinders.”
