How old the living Trajans are
born that year still alive today
Of the 787 babies given the name since 1994, about 780 are alive — 98 in every hundred. The dotted line is the median: half were born before 2005 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 Trajan is most common
Across the country Trajan is recorded 0.04 times per 100,000 births, so these are the states above that line. Only states with 50 or more recorded Trajans are ranked here: below that a handful of births makes a rate that moves on chance alone.
Counts favour the big states, which is why the same few lead this list for almost every name.
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.
