Recorded 1924–2014 · United States
Diann was most popular in 1947, when 557 American babies were given the name — ranking #623 that year. It was not recorded in 2025. Across 1880–2025 the Social Security Administration has recorded 12,252 people named Diann.
Diann first appears in Social Security Administration records in 1924, which makes it about 101 years old as a recorded American name. It has been recorded in 79 of the 102 years since. It was last recorded in 2014.
The Social Security Administration has recorded 12,252 American births named Diann 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 9,292 are estimated to be alive today.
Diann 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.
Diann is out of use. It averaged 6 births a year a decade ago and has not been recorded in the last five years.
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 Diann is a girl’s name — 100.0% of the 12,252 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 9,292 Americans named Diann are alive today — 76% of everyone ever recorded with the name. The median is 71 years old, and half are between 63 and 77.
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.
