Crosby is falling. Across 2021–2025 it averaged 235 births a year, against 415 a year across 2011–2015 — a change of -43% 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 Crosby is mostly a boy’s name — 9.4% of the 6,490 Americans given it were girls and 90.6% were boys. It changed hands: since 1999 it has gone mainly to boys, having gone mainly to girls before that. In births since 2016 it is 10% girls and 90% 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 6,171 Americans named Crosby are alive today — 95% of everyone ever recorded with the name. The median is 11 years old, and half are between 7 and 14. That is a narrow band because Crosby is a young name — it only became common recently, so almost everyone carrying it is still a child or a young adult.
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.
