Jason vs Niall

Jason and Niallcompared 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.

Jason and Niall over time

Jason and Niall appear together in 3 published lists, across 118 years of shared records. Niall held the stronger position in more years in 2 of them, Jason in 1.

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.

Jason reached its own highest recorded position earlier in 1 of those lists, and Niall 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.
