Beau vs Mary Kate

Beau and Mary Katecompared 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, Beau was ranked #608 and Mary Kate #885 among girls in Republic of Ireland.

Beau and Mary Kate over time

Beau and Mary Kate appear together in 1 published list, across 12 years of shared records. Beau held the stronger position in more years in 1 of them, Mary Kate in 0.

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

Mary Kate reached its own highest recorded position earlier in 1 of those lists, and Beau 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.
