Jenny and Katycompared 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

Jenny and Katy over time
Jenny and Katy appear together in 3 published lists, across 77 years of shared records. Katy held the stronger position in more years in 2 of them, Jenny in 1.
The order between them changed and held in 2 of those lists — a change in that published list, never a claim that one name displaced the other.
Jenny reached its own highest recorded position earlier in 2 of those lists, and Katy 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.
