Leif vs Shelby
Leif and Shelbycompared 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 2025, Leif was ranked #1007 and Shelby #2664 among boys in England and Wales.
Leif and Shelby over time
Leif and Shelby appear together in 1 published list, across 14 years of shared records. Leif held the stronger position in more years in 1 of them, Shelby 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.
Shelby 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.

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.
