Recorded 1969–2023 · United States
Chastity was most popular in 1974, when 749 American babies were given the name — ranking #568 that year. It was not recorded in 2025. Across 1880–2025 the Social Security Administration has recorded 9,711 people named Chastity.
Chastity first appears in Social Security Administration records in 1969, which makes it about 56 years old as a recorded American name. It has been recorded in 54 of the 57 years since.
The Social Security Administration has recorded 9,711 American births named Chastity 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 9,382 are estimated to be alive today.
Chastity 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.
Chastity is falling. Across 2021–2025 it averaged 8 births a year, against 33 a year across 2011–2015 — a change of -75% over the decade.
Measured on recorded births. American births overall have fallen since 2007, so most established names lose births over any recent decade — a name can shed births and still hold its rank. Compare the rank above, which is measured against the other names of the same year.
Across the whole record Chastity is a girl’s name — 100.0% of the 9,711 Americans given it were girls and 0.0% were boys. In births since 2016 it is 100% girls and 0% 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 9,382 Americans named Chastity are alive today — 97% of everyone ever recorded with the name. The median is 45 years old, and half are between 34 and 50.
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.
