Cassandra and Hayleycompared 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.

Cassandra and Hayley over time

Cassandra and Hayley appear together in 4 published lists, across 97 years of shared records. Hayley held the stronger position in more years in 4 of them, Cassandra 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.

Hayley reached its own highest recorded position earlier in 2 of those lists, Cassandra in 1. 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.
