Jack vs Ørnulf

Jack and Ørnulfcompared 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.

Norway · Boys
In 1975, Jack was ranked #493 and Ørnulf #589 among boys in Norway.

Jack and Ørnulf over time

Jack and Ørnulf appear together in 1 published list, across 30 years of shared records. Jack held the stronger position in more years in 1 of them, Ørnulf in 0.

In none of those lists did their order change and stay changed.

Ørnulf reached its own highest recorded position earlier in 1 of those lists, and Jack 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.
