Erin vs Gemma

Erin and Gemmacompared on official birth-registration statistics and Namewise's recorded data. This page states what each name's record shows — it never picks a winner or scores one name against the other.

Head to head

Ranks are only compared within one published list and one year. Two ranks from different years, from a boys' and a girls' list, or from different registrars are not comparable, so they are not placed side by side.

Erin and Gemma over time

Erin and Gemma appear together in 5 published lists, across 137 years of shared records. Erin held the stronger position in more years in 4 of them, Gemma in 1.

The order between them changed and held in 3 of those lists — a change in that published list, never a claim that one name displaced the other.

Gemma reached its own highest recorded position earlier in 3 of those lists, Erin in 1. Each position is a place inside its own list, so this compares when they peaked and never how high.

Counted list by list. Two names in the same published list are measured on the same scale in the same year, so those comparisons are real — but positions from different lists are not, so nothing here is combined into an overall standing.

Two names moving past each other in a ranking is a fact about the ranking. Namewise does not claim one name displaced the other, that families chose between them, or that either influenced the other — none of that is in this data.
