The Social Security Administration has recorded 1,063 American births named Locke 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 1,018 are estimated to be alive today.
65 American babies were named Locke in 2025, ranking #4,676 that year.
Locke is rising. Across 2021–2025 it averaged 58 births a year, against 44 a year across 2011–2015 — a change of +33% 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 Locke is a boy’s name — 0.0% of the 1,063 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 1,018 Americans named Locke are alive today — 96% of everyone ever recorded with the name. The median is 9 years old, and half are between 5 and 14. That is a narrow band because Locke 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.
How much more common the name is in each state than across the country as a whole.
