Charlie: The 53/47 Name

Nov 6, 2026 Abigail Adams, Editorial writer

Every other crossover in our files is a one-way street. Avery flipped to the girls in 1999 and never looked back. Leslie flipped and kept going until the boys' name ceased to exist.

Charlie is the exception — the crossover that won't finish. In 2025, Charlie went to 2,460 boys and 2,154 girls: 53% boys, 47% girls. And that mild-looking scoreline is the result of a lead that has changed hands twice in the last decade.

Act one: a boys' name (1910–2015)

Charlie began the data as a boys' name with a token girls' presence: in 1910, 1,073 boys (rank #33) and 51 girls — 95% male. He was still a top-100 boys' name in 1930 (2,082 boys) while the girls' side sat at 155.

Mid-century, both sides sank together. By 1970 the girls' Charlie had fallen below the reporting line entirely, and by 1990 the name hit its floor on both sides at once: 479 boys, 59 girls. Charlie looked like a name quietly retiring.

Act two: the girls take it (2016–2024)

The revival, when it came, came from both directions — but the girls ran faster. In 2010 it was still 1,409 boys to 639 girls. By 2015 the boys' lead was down to 1,660 against 1,542. And in 2016 the girls took Charlie outright: 1,751 to 1,694.

They then held the name for nine consecutive years — through a peak margin in 2019 (2,073 girls to 1,819 boys) and down to a photo-finish in 2024, when the girls' lead shrank to just 20 babies: 2,105 to 2,085. Anyone writing about Charlie in those years — us included — would have filed it as a standard crossover in progress: girls ahead, boys fading, ending foretold.

Act three: the boys take it back (2025)

Instead, 2025 flipped it. The boys' side jumped to 2,460, the girls' side eased to 2,154, and Charlie ended the year majority-boy for the first time since 2015.

One more twist hides in the ranks: the girls' Charlie, with fewer babies, ranks higher — #132 for girls against #144 for boys — because the girls' chart spreads its babies across more names at that level. By count, Charlie is a boys' name this year. By standing on its own chart, it's a slightly bigger girls' name. Both facts are true, which is about right for Charlie.

Why Charlie can do what Avery couldn't

Charlie has two engines. For boys it is fed by Charles, one of the most durable boys' names in the entire dataset. For girls it is fed by Charlotte — the #2 girls' name in America and the #1 name in 28 states (see our state-winner table), generating Charlies as a nickname at industrial scale. Avery depended on fashion alone, and fashion tips one way. Charlie's two feeders pull against each other, and the name sits in the tension — balanced, contested, and apparently stable there: it has now spent a full decade within a few hundred babies of even.

Our advice: Charlie is the safest genuinely-shared name in America — the one "unisex" pick whose balance is structural, not a moment between flips. A boy Charlie in 2025 joins 2,460 others; a girl Charlie joins 2,154. Neither will be the only one, neither will be read as borrowing the other sex's name, and the last ten years of data say that is still true whichever way next year tips — because with Charlie, next year tips both ways.

Both Charlies: Charlie (girl) and Charlie (boy). For the name that took the one-way version of this journey, see Avery (girl) and Avery (boy).
