Gro vs Silja
Gro and Siljacompared 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 · Girls
In 2006, Gro was ranked #557 and Silja #279 among girls in Norway.
Gro and Silja over time
Gro and Silja appear together in 1 published list, across 35 years of shared records. Gro held the stronger position in more years in 1 of them, Silja 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.
Gro reached its own highest recorded position earlier in 1 of those lists, and Silja 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.
