Cailum appears in 3 of the published lists Namewise holds. The longest record is England and Wales · Boys, which has ranked it in 13 years beginning in 1996, and has registered 47 births with the name.

Cailum across 3 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.

Cailum by decade in England and Wales · 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 1996 and 2021, ranked in 19 years of that period.

Its highest recorded position is #271, first reached in 1997.

Its largest count from any one registrar is 6 births, registered in Republic of Ireland in 2004.

Its record falls into 5 separate stretches, with a longest absence of 3 years.

A second registrar first ranked it in 1997, and 3 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.

Cailum was ranked #271 in Northern Ireland · Boys in 1997. 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.

Cailum 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 Cailum without appearing here.
