Is September a boy’s or a girl’s name?
September has been recorded only for girls: SSA lists no boys with the name in 71 years of records (it lists a name only in years with 5 or more babies of a sex).
Girls and boys named September: the SSA national file counts each sex separately.
How many people are named September, and how old are they?
2,110 alive in 2026, estimated
That is 96% of the 2,203 Americans ever recorded as September. The median September alive today is 35 years old; half are between 19 and 49.
The 2020 Census counted 1,779 people named September (1,748 women and girls, 31 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 2,000 born in the U.S. The Census count is 11% 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.

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