How old the living Unas are

born that year still alive today

Of the 8,108 babies given the name since 1880, about 2,700 are alive — 33 in every hundred. Roughly 830 of them are children and 920 are 65 or over. The dotted line is the median: half were born before 1976 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.

All the names of 1921

Una 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.

Una: 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, Una is most concentrated in Zurich, where 0.02% of children were given it – 52 of them.

Una: rank by region

In 2020, Una was given 2 times or more in 1 region of Poland.

Each of these is the top of a list the statistics office cut off somewhere – Poland below 2 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.

Una by city

One city over a few years, so these are much smaller numbers than the national ones above and not comparable with them.

Una 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.
