Ioan vs Keiran
Ioan and Keirancompared 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.

Ioan and Keiran over time
Ioan and Keiran appear together in 1 published list, across 28 years of shared records. Ioan held the stronger position in more years in 1 of them, Keiran 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.
Keiran reached its own highest recorded position earlier in 1 of those lists, and Ioan 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.
