How old the living Ruis are

born that year still alive today

Of the 972 babies given the name since 1967, about 940 are alive — 97 in every hundred. Roughly 550 of them are children and 0 are 65 or over. The dotted line is the median: half were born before 2012 and half after.

An estimate, not a count. SSA births aged forward through SSA cohort life tables, which know nothing about who left the country or arrived in it — so for a name that mostly came to America rather than being born in it, this is a floor rather than a figure. Where you fall among living Americans.

Rui elsewhere

Counts come from each country's own records and are not comparable with the US figures above, which cover different years and a different definition of a recorded name. Where a country writes the name several ways, the spellings are added together and the most common is shown. A row marked name registrations is counting something else: Portugal ranks each of a child's two given names separately, so a girl registered Maria Leonor is in both the Maria row and the Leonor row, and that figure is not a number of children.

Rui: births by region

Parts of a country counted above, not extra births. The share is what makes the regions comparable: they differ in size by a factor of three hundred.

By canton, Rui is most concentrated in Vaud, where 0.02% of children were given it – 28 of them.

Rui: rank by region

In 2024, Rui was given 5 times or more in 1 region of Belgium.

Each of these is the top of a list the statistics office cut off somewhere – Belgium below 5 children – and published nothing after. So a region missing here is one where the name fell outside what was published, not one where it went unused. Places are shared where names tie, and the further down a list a place is, the more names can share it.

Rui among the living

How many people each country's register counts under the name, rather than how many were given it in any one year. Each register was read on one date, and they are not the same date.

A count of people on a register – Finland on 4 August 2026 – and not of births, so it cannot be compared with the figures above. Names with very few bearers are withheld, and a dash in the first-forename column means the register would not say rather than that nobody goes by it.

Where Rui lives in Spain

Not a count of births but of people: 449 men called Rui were living in Spain on 1 January 2025, of every age, born in any year. Where they live is not spread evenly.

Men: the provinces where it is densest

Listed in 22 of Spain's 52 provinces. In the other 30 it is either held by fewer than 5 people – the point below which the source withholds a name – or it fell past the 5,000 names the source will print for one province. Neither means nobody there is called it. The rate is the source's own, not a share worked out here.
