Kacey vs Leif
Kacey and Leifcompared 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 · Boys
In 2024, Kacey was ranked #2921 and Leif #814 among boys in England and Wales.
Kacey and Leif over time
Kacey and Leif appear together in 1 published list, across 25 years of shared records. Kacey held the stronger position in more years in 1 of them, Leif 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.
Kacey reached its own highest recorded position earlier in 1 of those lists, and Leif 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.
