Aila vs Sia
Aila and Siacompared 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.

Aila and Sia over time
Aila and Sia appear together in 1 published list, across 25 years of shared records. Aila held the stronger position in more years in 1 of them, Sia 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.
Sia reached its own highest recorded position earlier in 1 of those lists, and Aila 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.
