Recorded 1973–2019 · United States
Brittanie was most popular in 1990, when 429 American babies were given the name — ranking #1,027 that year. It was not recorded in 2025. Across 1880–2025 the Social Security Administration has recorded 4,738 people named Brittanie.
Brittanie first appears in Social Security Administration records in 1973, which makes it about 52 years old as a recorded American name. It has been recorded in 43 of the 53 years since. It was last recorded in 2019.
The Social Security Administration has recorded 4,738 American births named Brittanie 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 4,640 are estimated to be alive today.
Brittanie was not recorded in 2025. The SSA withholds any name given to fewer than five babies in a year, so fewer than five American babies were given it.
Brittanie is out of use. It averaged 9 births a year a decade ago and has not been recorded in the last five years.
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 Brittanie is a girl’s name — 100.0% of the 4,738 Americans given it were girls and 0.0% 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 4,640 Americans named Brittanie are alive today — 98% of everyone ever recorded with the name. The median is 35 years old, and half are between 32 and 38. That is a narrow band: Brittanie 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.
