Luca and Riahcompared 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.

Luca and Riah over time
Luca and Riah appear together in 1 published list, across 27 years of shared records. Luca held the stronger position in more years in 1 of them, Riah 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.
Riah reached its own highest recorded position earlier in 1 of those lists, and Luca 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.
