How many people are named Glennis?
The Social Security Administration has recorded 2,777 American births named Glennis 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 1,323 are estimated to be alive today.

Across the whole record Glennis is a unisex name — 74.0% of the 2,777 Americans given it were girls and 26.0% were boys. It changed hands: since 1959 it has gone mainly to girls, having gone mainly to boys before that.
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 Glennis?
Roughly 1,323 Americans named Glennis are alive today — 48% of everyone ever recorded with the name. The median is 72 years old, and half are between 62 and 80.
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.
