The Social Security Administration has recorded 22,247 American births named Tonia between 1880 and 2025. That is recorded US births, not a world population — it counts people issued a Social Security number at birth in the United States. Of those, roughly 20,322 are estimated to be alive today.
5 American babies were named Tonia in 2025, ranking #24,763 that year.
Tonia is too rare for a direction to mean much. It averaged 5 births a year across 2021–2025 against 9 a year a decade earlier — at these counts a single baby moves the percentage, and any year under five births is withheld at source.
Measured on recorded births. American births overall have fallen since 2007, so most established names lose births over any recent decade — a name can shed births and still hold its rank. Compare the rank above, which is measured against the other names of the same year.
Across the whole record Tonia is a girl’s name — 99.8% of the 22,247 Americans given it were girls and 0.2% were boys. In births since 2016 it is 100% girls and 0% boys.
Counted from every US birth the Social Security Administration recorded under this name, so it reflects use rather than opinion. A name given to fewer than five babies of one sex in a year is withheld at source and is not counted.
Roughly 20,322 Americans named Tonia are alive today — 91% of everyone ever recorded with the name. The median is 55 years old, and half are between 50 and 59. That is a narrow band: Tonia arrived and faded within about a decade rather than staying in steady use.
An estimate, not a count. Recorded births are carried forward through the Social Security Administration’s 2023 period life table, by age and sex. That table describes mortality in one recent year, so it credits the oldest cohorts with today’s survival rather than the harsher rates they actually lived through — the further back a name peaked, the more this will overstate how many remain. It counts people issued a Social Security number at birth, not immigrants who arrived later.
How much more common the name is in each state than across the country as a whole.
