born that year still alive today

Of the 218,463 babies given the name since 1881, about 212,000 are alive — 97 in every hundred. Roughly 151,000 of them are children and 760 are 65 or over. The dotted line is the median: half were born before 2014 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.

Where the name comes from

Origin Latin, Ancient Greek

From Latin Sebastiānus, name of an early Christian saint, from ancient city of Sebaste in Asia Minor (modern Sivas, Turkey), from Ancient Greek Σεβαστός (“august, venerable, exalted”), itself a translation of the Roman title Augustus.

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.

In 2025, with the country taken in 11 areas rather than 3, Sebastian appears in the lists for Province of Flemish Brabant (112th), Province of Antwerp (181st) and Brussels-Capital Region (187th).

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

Sebastian 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 boys Sebastian +1 spelling 3,505 15,581
the Netherlands boys Sebastian 1,867 4,124
Finland girls Sebastian 6 31
the Netherlands girls Sebastian 10

Among boys in Finland this is mostly a middle name: of the 15,581 who carry it, 3,505 go by it.

A count of people on a register – Finland on 4 August 2026, the Netherlands on 1 January 2018 – 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 Sebastian lives in Spain

Not a count of births but of people: 44,158 men called Sebastian were living in Spain on 1 January 2025, of every age, born in any year. Where they live is not spread evenly.

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.
