How old the living Flos are
born that year still alive today
Of the 2,094 babies given the name since 1881, about 430 are alive — 20 in every hundred. The dotted line is the median: half were born before 1947 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.
Flo: rank by region
In 2025, Flo was given 5 times or more in 1 region of Belgium.
| Region | Spelling | Place | Children |
|---|---|---|---|
| Flanders | Flo | 27 | 122 |
In 2025, with the country taken in 11 areas rather than 3, Flo appears in the lists for Province of Antwerp (15th), Province of Limburg (22nd), Province of East Flanders (28th), Province of West Flanders (44th) and Province of Flemish Brabant (48th).
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.

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.
