Dylan vs Jason
Dylan and Jasoncompared 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.

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.

| Meaning | Traditionally associated with the sea/tide — popularly glossed as 'great tide' or 'born from the sea', reflecting the mythological figure's role. Some scholars theorise the figure may reflect an earlier, otherwise unattested Celtic sea god — treat as a proposed origin, not settled fact. | From Ancient Greek Iason, meaning 'healer'. In Greek mythology, Jason led the Argonauts in the quest for the Golden Fleece; the name also appears in the New Testament as a Hellenized form possibly of a Hebrew name. |
