Isabelle

Isabelle across 6 registrars

• Its last ten ranked years point in different directions: up in Northern Ireland, down in Norway, England and Wales, New South Wales, Australia and New Zealand.
• The longest ranked record is in Norway, from 1962 to 2025.

Each panel runs 1962 to 2025, top of the panel is #1 on a log scale, with guide lines at #1 and #100. Filled dot: best rank. Open dot: latest rank. Read from 6 official registrars with at least 10 ranked years. Where a registrar publishes separate lists by sex, the better rank for each year is used. A 'meaningful' move is 10 or more places. Lists start in different years, so an earlier first year shows the list is older, not that the name arrived there first, and a best rank in the first years of a list is not compared as a peak. Ranks show position, and cannot show why a name moved.

Where Isabelle is officially recorded

7 official registrars have recorded Isabelle, between 1962 and 2025, in 59 of those 64 years. Each registrar publishes for its own population on its own methodology, so the positions below are each one country's own ranking and are not comparable with one another.

Its high point came 16 years earlier in England and Wales (2008) than in Scotland (2024).

No registrar recorded it for 3 years after 1966; it appears again in 1970.
