How old the living Siobhans are
born that year still alive today
Of the 7,399 babies given the name since 1956, about 7,100 are alive — 96 in every hundred. Roughly 1,200 of them are children and 300 are 65 or over. The dotted line is the median: half were born before 1987 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 Irish
Anglicized spelling of Irish Siobhán, from Middle Irish Sibán, from Anglo-Norman Jehane or Jehanne, from Old French Jehanne, from Medieval Latin Johanna, variant of Joanna, from Koine Greek Ἰωάννα, from Hebrew יוֹחָנָה, the feminized form of יְהוֹחָנָן or יוֹחָנָן, which produced John and its many doublets.

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.
Siobhan 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.

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.
