Mia vs Rosie

Mia and Rosiecompared 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.

Mia and Rosie over time

Mia and Rosie appear together in 3 published lists, across 91 years of shared records. Mia held the stronger position in more years in 3 of them, Rosie in 0.

In none of those lists did their order change and stay changed.

Mia reached its own highest recorded position earlier in 3 of those lists, and Rosie in none. 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.
