Sonni vs Sonnie

Babies given each name, 1880–2025

Sonni Sonnie

Each line is every baby given the name that year, girls and boys added together — the only count that means the same thing for both names. A line breaks where the name fell below five babies in a year — the point at which the SSA stops publishing it — rather than being drawn through a figure nobody published. A single published year in a gap shows as a dot.

Who was ahead

Of the 118 years in which either name was published, Sonnie for 107 years and Sonni for 11 years. The lead changed hands 16 times.

• 1893–1981 Sonnie ahead, apart from one short spell
• 1982–1984 Sonni ahead
• 1985–2025 Sonnie ahead, apart from 3 short spells

10 shorter spells of a year or two are folded into the spans above rather than listed separately.

Side by side

A rank is a position within one sex’s list for one year, so the two rank rows are not subtracted from one another and the winning column is not marked on them. The living figure is a life-table estimate, not a count.

Both names abroad

Countries whose statistics office publishes both names, so the comparison can be made somewhere other than the United States.

Every spelling a country files separately is added together, over whatever years that country publishes — which is not the same range in any two of them, so read the columns against each other and not the rows.
