How old the living Onas are

Born with the name each year, and how many of them are alive today, 1880 to 2025 0 50 100 150 200 1880 1900 1920 1940 1960 1980 2000 2020

born that year still alive today

Of the 8,031 babies given the name since 1880, about 2,200 are alive — 28 in every hundred. Roughly 490 of them are children and 980 are 65 or over. The dotted line is the median: half were born before 1967 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.

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.

Ona: rank by region

In 2025, Ona was given 5 times or more in 1 region of Belgium.

Region Spelling Place Children
Flanders Ona 153 37

In 2024, Ona was among the 10 most common names in 1 region of Spain.

Region Spelling Place Children
Cataluña Ona 5 320

In 2025, with the country taken in 11 areas rather than 3, Ona appears in the lists for Province of Antwerp (128th), Province of West Flanders (138th) and Province of East Flanders (154th).

Each of these is the top of a list the statistics office cut off somewhere – Belgium below 5 children, Spain after 10 names – 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.

Ona 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.

Country Spelling First forename Any forename
Finland girls Ona 114 142

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 Ona lives in Spain

Not a count of births but of people: 9,463 women called Ona were living in Spain on 1 January 2025, of every age, born in any year. Where they live is not spread evenly.

Listed in 26 of Spain's 52 provinces. In the other 26 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.

Source: US Social Security Administration, national and state baby-name files, 1880–2025. Counts include only births registered with the SSA, and names with fewer than five births in a year are not published. The living estimate applies SSA cohort life tables to those births; it counts people born in the United States, so it misses anyone who arrived later and anyone who has left.
