Is Dian a boy’s or a girl’s name?
Of the 5,578 Americans recorded as Dian, 96% are girls and 4% boys. In 2025 it went to 11 boys; SSA lists no girls with it that year (fewer than 5, or none).
Years with fewer than 20 babies given the name are left blank.
Girls and boys named Dian: the SSA national file counts each sex separately.
How many people are named Dian, and how old are they?
3,780 alive in 2026, estimated
That is 68% of the 5,578 Americans ever recorded as Dian. The median Dian alive today is 72 years old; half are between 62 and 79.
The 2020 Census counted 5,975 people named Dian (5,457 women and girls, 518 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 4,232 born in the U.S. The Census count is 41% above that prediction. Possible reasons: the Census records the name people give, which for many is the short form Dian rather than the name on their birth record, and it counts people born abroad, whom SSA’s files leave out.

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).

Where Dian is more common than its national share predicts
Relative to its national share, Dian is most over-represented in California: since 1912 it was given 1.1 times as often there as its national share each year would predict.
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 Dian with the births its national share predicts year by year, for states with at least 100 births of the name.
Names spelled alike
Of these 5 names spelled alike, given to 20,817 babies since 1880, Dian is the second most given (27% of them).
