How many people are named Gwynn, and how old are they?
An estimated 883 Americans named Gwynn and born in the U.S. are alive in 2026 (75% of everyone recorded); the median is 59 years old and half are between 16 and 72. An estimate from SSA’s births and life tables, not a count.
The 2020 Census counted 1,082 people named Gwynn (974 women and girls, 108 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 895 born in the U.S. The Census count is 21% 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).
