How many people are named Jonasia, and how old are they?
An estimated 206 Americans named Jonasia and born in the U.S. are alive in 2026 (99% of everyone recorded); the median is 22 years old and half are between 19 and 25. An estimate from SSA’s births and life tables, not a count.
The 2020 Census counted 156 people named Jonasia (155 women and girls, 1 man or boy). SSA’s births carried forward to Census day, April 1, 2020, predict 201 born in the U.S. The Census count is 22% below that prediction. Possible reasons: people who give a short form or another name to the Census, and a survival estimate that can run high.
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).
