What are the commonest baby names in your borough?
Every year, the Office for National Statistics releases data on the commonest baby names registered over the past year. The 2025 data have now been released. As usual, the London stats are broken down by borough, allowing us to make the graphic above.
Commonest girls’ names in London boroughs
Among girls, Sophia and Sofia are the commonest name, topping 10 boroughs between them. That’s quite a surge, as the name only featured in two boroughs last year. Maryam is also on the rise. Last year, only Tower Hamlets recorded this as the most popular choice; now five boroughs do.
The biggest decline is in Amelias. A whopping 14 boroughs favoured the name in 2024, now it’s just two. Olivia has also stagnated, from seven boroughs last year to seven this.
And welcome to the new entry of Rehmat, the commonest girl’s name in the London Borough of Hillingdon.
