How many people are named Dyan, and how old are they?
1,750 alive in 2026, estimated
That is 91% of the 1,928 Americans ever recorded as Dyan. The median Dyan alive today is 54 years old; half are between 44 and 59.
The 2020 Census counted 2,445 people named Dyan (2,156 women and girls, 289 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 1,760 born in the U.S. The Census count is 39% above 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.

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 Dyan with the births its national share predicts year by year, for states with at least 100 births of the name.
