Kaj across 2 official records

Each registrar publishes its own list, so these figures are read down a row, never across one. A position in one country is not comparable with a position in another, and Namewise never combines them into a single ranking. The birth counts do not compare across rows either, for a different reason: England and Wales registers roughly thirty times as many births a year as Northern Ireland, so a larger total says which registrar recorded it as much as how widely the name was given.

Kaj by decade in Norway · Boys

Births registered with the name in each decade of this one list, with the number of years the list covers in that decade. Bars are scaled on births a year, which is the figure that compares between decades — a decade the list only partly covers has a smaller total without being a quieter decade. Figures belong to this registrar alone and do not carry to another.

What the record shows

Recorded by 3 registrars between 1945 and 2023, ranked in 55 years of that period.

Its highest recorded position is #216, first reached in 1959.

Its largest count from any one registrar is 17 births, registered in Norway in 1959.

Its record falls into 16 separate stretches, with a longest absence of 4 years.

A second registrar first ranked it in 1996, and 78 years separate the first registrar to record it from the last.

Every figure here is counted from the seven official registrars Namewise holds. A position is only ever a place within the list that published it, and a record that thins or stops is a fact about what registrars printed — never about how many children received the name.

Kaj was ranked #216 in Norway · Boys in 1959. These are the names immediately either side of it on that published list — a fact about the registrar's own output, not a similarity judgement.

Kaj and the names beside it

Two names in the same published list are measured on the same scale, in the same year, by the same registrar — so these are positions that genuinely passed each other, not a similarity judgement. Drawn from the 2,573 names with a recorded popularity standing (common, familiar, uncommon), so a name outside that set could have passed Kaj without appearing here.

Absence from this list does not mean the name isn't genuinely meaningful or widely used — only that Namewise hasn't sourced and reviewed that content yet. Absence from a specific year or geography above does not prove zero use there either; official statistics only publish names above a minimum threshold.
