Seneca crossed from boys to girls in 1987, having already crossed in 1976, and has stayed there for 15 of the years counted since. At its furthest it was 85% girls, and in 2025 it was 67%.
The girls’ share of each year’s babies of the name, in the 51 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 Senecas are
born that year still alive today
Of the 3,523 babies given the name since 1956, about 3,400 are alive — 96 in every hundred. Roughly 910 of them are children and 50 are 65 or over. The dotted line is the median: half were born before 1995 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.

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.
