Colleen 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.

Colleen and Mona over time
Colleen and Mona appear together in 2 published lists, across 39 years of shared records. Neither was ahead in more lists than the other.
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.
