Kai vs Marcy
Kai and Marcycompared 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.
England and Wales · Girls
In 2024, Kai was ranked #4843 and Marcy #3015 among girls in England and Wales.
Kai and Marcy over time
Kai and Marcy appear together in 1 published list, across 23 years of shared records. Marcy held the stronger position in more years in 1 of them, Kai 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.
Kai reached its own highest recorded position earlier in 1 of those lists, and Marcy 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.
