Meaning
variant of Joan, traditionally God is gracious
The story
Joni is a midcentury American spin on Joan, which itself traces to the Hebrew for God is gracious, and its strongest run in the records came at midcentury, when Jonis shared classrooms with Judys and Jans. One of those midcentury Joans was Roberta Joan Anderson of the Canadian prairies, who folded her name into Joni, moved to Laurel Canyon, and as Joni Mitchell wrote Both Sides Now and the 1971 album Blue, routinely ranked among the greatest ever made, turning confession into architecture. Interestingly, her fame arrived just after the name's best years, so the chart tells the story of her generation rather than her influence: Joni has been quiet since the 1970s, though it never entirely left the records. For parents who love her, it is that rare thing, a name whose most famous bearer is also its best argument.

Not on the record in Mexico City, Argentina, Puerto Rico and Poland: those registries withhold small counts, so rare uses may sit below their floors.
Not on the Chile record: nametree keeps spellings that reached 5 registrations in some year, so rarer uses are not shown. Not on the France record: nametree keeps spellings that reached 20 births in some year, so rarer uses are not shown. Not on Norway’s list: Statistics Norway lists only first names carried by 200 or more living people, so rarer names are not shown.
