How many people are named Dillion, and how old are they?
3,560 alive in 2026, estimated
That is 97% of the 3,661 Americans ever recorded as Dillion. The median Dillion alive today is 28 years old; half are between 22 and 33.
The 2020 Census counted 3,882 people named Dillion (55 women and girls, 3,827 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 3,474 born in the U.S. The Census count is 12% 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.

| Generation | Born | Alive |
|---|---|---|
| Generation X | 1965-1980 | 12 |

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 Dillion is more common than its national share predicts
Relative to its national share, Dillion is most over-represented in Kentucky: since 1979 it was given 2.1 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 boys’ 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 Dillion with the births its national share predicts year by year, for states with at least 100 births of the name.
