Recorded 1938–2001 · United States
Kathi was most popular in 1958, when 824 American babies were given the name — ranking #587 that year. It was not recorded in 2025. Across 1880–2025 the Social Security Administration has recorded 10,109 people named Kathi.
Kathi first appears in Social Security Administration records in 1938, which makes it about 87 years old as a recorded American name. It has been recorded in 60 of the 88 years since. It was last recorded in 2001.
The Social Security Administration has recorded 10,109 American births named Kathi 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 8,493 are estimated to be alive today.
Kathi was not recorded in 2025. The SSA withholds any name given to fewer than five babies in a year, so fewer than five American babies were given it.
Across the whole record Kathi is a girl’s name — 100.0% of the 10,109 Americans given it were girls and 0.0% 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.
Roughly 8,493 Americans named Kathi are alive today — 84% of everyone ever recorded with the name. The median is 67 years old, and half are between 62 and 71. That is a narrow band: Kathi 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.
How much more common the name is in each state than across the country as a whole.
