Nils vs Rollo
Nils and Rollocompared 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, Nils was ranked #4270 and Rollo #1859 among boys in England and Wales.
Nils and Rollo over time
Nils and Rollo appear together in 1 published list, across 19 years of shared records. Nils held the stronger position in more years in 1 of them, Rollo 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.
Nils reached its own highest recorded position earlier in 1 of those lists, and Rollo 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.
