Is Katy a boy’s or a girl’s name?
Katy has been given almost only to girls: 5 boys in 144 years of records.
Girls and boys named Katy: the SSA national file counts each sex separately.
How many people are named Katy, and how old are they?
18,200 alive in 2026, estimated
That is 87% of the 20,957 Americans ever recorded as Katy. The median Katy alive today is 39 years old; half are between 28 and 47.
The 2020 Census counted 23,113 people named Katy (23,074 women and girls, 39 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 18,189 born in the U.S. The Census count is 27% 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.

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 Katy is more common than its national share predicts
Relative to its national share, Katy is most over-represented in Texas: since 1910 it was given 2.0 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 Katy with the births its national share predicts year by year, for states with at least 100 births of the name.
Names spelled alike
Of these 8 names spelled alike, given to 367,252 babies since 1880, Katy is the third most given (5.7% of them). In 2025 it was given to 64 of their 1,233 babies (5.2%), the fourth most given that year.
