Dortha was most popular in 1921, when 295 American babies were given the name — ranking #736 that year. It was not recorded in 2025. Across 1880–2025 the Social Security Administration has recorded 6,811 people named Dortha.
Dortha first appears in Social Security Administration records in 1889, which makes it about 136 years old as a recorded American name. It has been recorded in 88 of the 137 years since. It was last recorded in 1984.
The Social Security Administration has recorded 6,811 American births named Dortha 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 1,234 are estimated to be alive today.
Dortha 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 Dortha is a girl’s name — 100.0% of the 6,811 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 1,234 Americans named Dortha are alive today — 18% of everyone ever recorded with the name. The median is 81 years old, and half are between 72 and 88.
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.
