Is Thedora a boy’s or a girl’s name?

Girls and boys named Thedora: the SSA national file counts each sex separately.
How many people are named Thedora, and how old are they?
An estimated 31 Americans named Thedora and born in the U.S. are alive in 2026, too few to state an age range. An estimate from SSA’s births and life tables, not a count.
The 2020 Census counted 104 people named Thedora (98 women and girls, 6 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 40 born in the U.S. The Census count is 2.6 times that prediction. Possible reasons: the Census counts people born abroad, whom SSA’s files leave out, and it records the name people give, which SSA may have recorded under another spelling or as part of a compound name.
Living estimate: SSA births carried forward with the survival rates in SSA’s cohort life tables (2024 Trustees Report) for each birth year and sex. How the estimate is made. Count: Census Bureau, first names in the 2020 Census (released April 14, 2026; names reported 100 or more times, with the Bureau’s disclosure-avoidance adjustment).
Names spelled alike
Of these 3 names spelled alike, given to 14,313 babies since 1880, Thedora is the third most given (<1% of them). In 2025 none of their 470 babies recorded by SSA was a Thedora (SSA lists a name only with 5 or more babies of one sex).
Spelled alike: names in the SSA national file with the same pattern of letters and sounds and at most two letters apart, and Wiktionary’s listed forms; births since 1880 and in 2025, and each name’s peak year, from the SSA national file, published May 8, 2026. Some are separate names, not spellings of one.
