How many people are named Ka?
The Social Security Administration has recorded 917 American births named Ka between 1880 and 2025. That is recorded US births, not a world population — it counts people issued a Social Security number at birth in the United States. Of those, roughly 892 are estimated to be alive today.

Across the whole record Ka is mostly a girl’s name — 85.2% of the 917 Americans given it were girls and 14.8% were boys.
Counted from every US birth the Social Security Administration recorded under this name, so it reflects use rather than opinion. A name given to fewer than five babies of one sex in a year is withheld at source and is not counted.
How old is someone named Ka?
Roughly 892 Americans named Ka are alive today — 97% of everyone ever recorded with the name. The median is 36 years old, and half are between 32 and 41. That is a narrow band: Ka arrived and faded within about a decade rather than staying in steady use.
An estimate, not a count. Recorded births are carried forward through the Social Security Administration’s 2023 period life table, by age and sex. That table describes mortality in one recent year, so it credits the oldest cohorts with today’s survival rather than the harsher rates they actually lived through — the further back a name peaked, the more this will overstate how many remain. It counts people issued a Social Security number at birth, not immigrants who arrived later.
