Hayley and Monacompared 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.

Hayley and Mona over time
Hayley and Mona appear together in 2 published lists, across 50 years of shared records. Hayley held the stronger position in more years in 2 of them, Mona 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.
Each reached its own highest recorded position first in 1 of the lists they share.
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.

Two names moving past each other in a ranking is a fact about the ranking. Namewise does not claim one name displaced the other, that families chose between them, or that either influenced the other — none of that is in this data.
