* ONS’s girls’ 2013 file repeats the May total as April, so the 2013 births total is about 1,360 too high and 1 in X for 2013 is slightly too high. 1 in X is not shown for girls in 1998: one monthly total is missing from the ONS girls’ 1998 file. 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.
