How many people are named Sierrah, and how old are they?
1,130 alive in 2026, estimated
That is 99% of the 1,150 Americans ever recorded as Sierrah. The median Sierrah alive today is 25 years old; half are between 21 and 30.
The 2020 Census counted 936 people named Sierrah (936 women and girls, 0 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 1,122 born in the U.S. The Census count is 17% 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.

| Generation | Born | Alive |
|---|---|---|

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