How old the living Leoncios are

born that year still alive today

Of the 523 babies given the name since 1951, about 490 are alive — 94 in every hundred. The dotted line is the median: half were born before 1996 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.

Where Leoncio lives in Spain

Listed in 49 of Spain's 52 provinces. In the other 3 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.
