How old the living Alfonzos are
born that year still alive today
Of the 5,783 babies given the name since 1889, about 4,000 are alive — 70 in every hundred. Roughly 490 of them are children and 800 are 65 or over. The dotted line is the median: half were born before 1979 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.
