Namewise

Within 2 years

Names where the first and last registrar to rank them are 0 to 2 years apart.

This measures when registrars began publishing a name, not the name itself moving anywhere. Registrars start publishing in different years — Norway from 1945, Scotland from 2014 — so a long gap often reflects when a source began rather than anything about the name. Single-registrar names have no gap at all and appear in none of these bands.
