born that year still alive today

Of the 267 babies given the name since 2009, about 270 are alive — 99 in every hundred. The dotted line is the median: half were born before 2016 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 Jayko is most common

  • NJ0.11
  • FL0.04
  • TX0.02
  • CA0.02

Across the country Jayko is recorded 0.01 times per 100,000 births, so these are the states above that line. Only states with 50 or more recorded Jaykos are ranked here: below that a handful of births makes a rate that moves on chance alone.

  • NJ10
  • CA6
  • TX5
  • FL5

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.
