Rio appears in 4 of the published lists Namewise holds. The longest record is England and Wales · Boys, which has ranked it in 29 years beginning in 1996, and has registered 6,567 births with the name.

Rio across 4 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.

Rio 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 4 registrars between 1996 and 2025, ranked in 30 years of that period.

Its highest recorded position is #110, first reached in 2024.

Its largest count from any one registrar is 359 births, registered in England and Wales in 2011.

1 registrar publishes it in more than one category list, holding a place in each for at least five years — an observation about those lists rather than about the name.

A second registrar first ranked it in 2002, and 28 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.

Rio was ranked #110 in Scotland · Boys in 2024. 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.

Rio 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 Rio 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.
