* ONS’s boys’ 2016 file repeats the October total as September, so the 2016 births total is about 932 too low and 1 in X for 2016 is slightly too low. Rank follows ONS: names with the same count share a rank (shown with =). “Under 3” means the name was given to fewer than 3 babies that year, so ONS did not publish it.
