Girls' names by letter
Boys' names by letter
Shares and counts come from official births data for 1880–2025. A name given to fewer than 5 babies of one sex in a year is not published, so “names in use” counts names that cleared that floor — the true number of distinct names is higher, and the shortfall is largest for letters carrying many rare names.
