The Social Security Administration has recorded 641 American births named Petar 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 618 are estimated to be alive today.
14 American babies were named Petar in 2025, ranking #12,918 that year.
Petar is too rare for a direction to mean much. It averaged 14 births a year across 2021–2025 against 12 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 Petar is a boy’s name — 0.0% of the 641 Americans given it were girls and 100.0% were boys. In births since 2016 it is 0% girls and 100% 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 618 Americans named Petar are alive today — 96% of everyone ever recorded with the name. The median is 23 years old, and half are between 11 and 37.
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.
