The Social Security Administration has recorded 9,720 American births named Trinidad 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 5,156 are estimated to be alive today.
15 American babies were named Trinidad in 2025, ranking #12,329 that year.
Trinidad is holding steady. Across 2021–2025 it averaged 30 births a year, against 38 a year across 2011–2015 — a change of -20% over the decade.
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 Trinidad is a unisex name — 44.8% of the 9,720 Americans given it were girls and 55.2% were boys. It changed hands: since 1962 it has gone mainly to boys, having gone mainly to girls before that. In births since 2016 it is 32% girls and 68% 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 5,156 Americans named Trinidad are alive today — 53% of everyone ever recorded with the name. The median is 46 years old, and half are between 28 and 66. That is a wide band, the mark of a name in steady use across generations rather than a passing fashion.
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.
