Ava vs Róisín

Ava and Róisíncompared 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.

Republic of Ireland · Girls
In 2025, Ava was ranked #26 and Róisín #29 among girls in Republic of Ireland.

Ava and Róisín over time

Ava and Róisín appear together in 1 published list, across 8 years of shared records. Ava held the stronger position in more years in 1 of them, Róisín in 0.

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

Ava reached its own highest recorded position earlier in 1 of those lists, and Róisín 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.
