Girls and boys named Cybill: the SSA national file counts each sex separately.
How many people are named Cybill, and how old are they?
An estimated 129 Americans named Cybill and born in the U.S. are alive in 2026 (96% of everyone recorded); the median is 41 years old and half are between 37 and 53. An estimate from SSA’s births and life tables, not a count.
The 2020 Census counted 180 people named Cybill (179 women and girls, 1 man or boy). SSA’s births carried forward to Census day, April 1, 2020, predict 131 born in the U.S. The Census count is 37% 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.
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).
