How many people are named Masen, and how old are they?
3,300 alive in 2026, estimated
That is 99% of the 3,335 Americans ever recorded as Masen. The median Masen alive today is 14 years old; half are between 11 and 20.
The 2020 Census counted 2,579 people named Masen (102 women and girls, 2,477 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 2,971 born in the U.S. The Census count is 13% 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.
Alive today, by age
Alive today, by generation
| Generation | Born | Alive |
|---|---|---|
| Millennials | 1981-1996 | 93 |
| Generation Z | 1997-2012 | 1,880 |
| Generation Alpha | 2013-2025 | 1,320 |
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 are babies named Masen born?
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 Masen with the births its national share predicts year by year, for states with at least 100 births of the name.
