Is Klaus a boy’s or a girl’s name?
Klaus has been recorded only for boys: SSA lists no girls with the name in 70 years of records (it lists a name only in years with 5 or more babies of a sex).
Girls and boys named Klaus: the SSA national file counts each sex separately.
How many people are named Klaus, and how old are they?
1,370 alive in 2026, estimated
That is 93% of the 1,471 Americans ever recorded as Klaus. The median Klaus alive today is 14 years old; half are between 5 and 48.
The 2020 Census counted 3,606 people named Klaus (4 women and girls, 3,602 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 1,010 born in the U.S. The Census count is 3.6 times 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.

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