Is Diedre a boy’s or a girl’s name?

Girls and boys named Diedre: the SSA national file counts each sex separately.
How many people are named Diedre, and how old are they?
1,580 alive in 2026, estimated
That is 88% of the 1,795 Americans ever recorded as Diedre. The median Diedre alive today is 57 years old; half are between 46 and 65.
The 2020 Census counted 1,469 people named Diedre (1,459 women and girls, 10 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 1,645 born in the U.S. The Census count is 11% below that prediction. Possible reasons: people who give a short form or another name to the Census, and a survival estimate that can run high.

An estimate, not a count. SSA’s files count people born in the United States who received a Social Security number, so anyone born abroad is not in them; before 1937 most people got a number as adults, and their survival is counted from that age.
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).

States: SSA state file, 1910-2025, published May 8, 2026; births count girls and boys together, and the rank is among girls’ names in the state in 2025. The file leaves out any state and year with fewer than 5 babies of the name, so small states are undercounted; each ratio compares the state’s births of Diedre with the births its national share predicts year by year, for states with at least 100 births of the name.
