Jon vs Leif

Jon 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, Jon was ranked #1758 and Leif #814 among boys in England and Wales.

Jon and Leif over time

Jon and Leif appear together in 2 published lists, across 107 years of shared records. Jon held the stronger position in more years in 2 of them, Leif in 0.

The order between them changed and held in 2 of those lists — a change in that published list, never a claim that one name displaced the other.

Each reached its own highest recorded position first in 1 of the lists they share.

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.
