Ranks and shares: girls’ names in each year’s SSA file; share of all girls SSA recorded that year.
Is Flo a boy’s or a girl’s name?
Flo has been recorded only for girls: SSA lists no boys with the name in 85 years of records (it lists a name only in years with 5 or more babies of a sex).
Girls and boys named Flo: the SSA national file counts each sex separately.
How many people are named Flo, and how old are they?
An estimated 406 Americans named Flo and born in the U.S. are alive in 2026 (19% of everyone recorded); the median is 79 years old and half are between 70 and 86. An estimate from SSA’s births and life tables, not a count.
The 2020 Census counted 1,532 people named Flo (1,466 women and girls, 66 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 568 born in the U.S. The Census count is 2.7 times that prediction. Possible reasons: the Census records the name people give, which for many is the short form Flo rather than the name on their birth record, and it counts people born abroad, whom SSA’s files leave out.
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 Flo is more common than its national share predicts
Relative to its national share, Flo is most over-represented in Texas: since 1910 it was given 1.1 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 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 Flo with the births its national share predicts year by year, for states with at least 100 births of the name.
