How old the living Unkowns are
born that year still alive today
Of the 91 babies given the name since 1995, about 90 are alive — 98 in every hundred. The dotted line is the median: half were born before 1997 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 Unkown is most common
Births recorded in each state since 1910. A name given to fewer than five babies in one state in one year is not published, so a name's quietest states are missing from this rather than showing zero. Browse names by state.

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.
