Both, throughout, without either side ever taking it over: 580 girls and 850 boys in all, and in 1998 the split was 16 to 13.

The girls’ share of each year’s babies of the name, in the 19 years in which at least 25 babies got it. The line touches the middle more often than there are crossings marked: a year or two on the other side is not a name changing hands, and only a move that holds for 5 counted years and reaches 60/40 is recorded as one. All 581 names that changed sex.

How old the living Baos are

born that year still alive today

Of the 1,430 babies given the name since 1976, about 1,400 are alive — 97 in every hundred. The dotted line is the median: half were born before 1992 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.

One city over a few years, so these are much smaller numbers than the national ones above and not comparable with them.

Bao 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 Bao 42 94
Finland boys Bao 14 84

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.
