Over thirty years

From 1996 to 2025, Olivia was the top girls’ name in 146 of the 360 months, and Jack the top boys’ name in 135†. A month’s number one is not always the year’s number one. In a single month the top names are often only a few babies apart, so the order can change from month to month.

Exact spellings are counted separately. Names with the same count share a rank; ranks are worked out from ONS’s published counts, because in a few older tables ONS’s printed rank does not match its own counts (for example girls, November 2011, where Amelia and Olivia are both printed as 1 but Amelia had 502 babies and Olivia 414). ONS publishes only the top 10 for each month, so a name not shown may still have been given to many babies that month. The monthly total for girls born in October 1998 is blank in the ONS file. † Baby Data count of the published lists.
