Recorded 1880–2023 · United States
Dock was most popular in 1920, when 128 American babies were given the name — ranking #1,163 that year. It was not recorded in 2025. Across 1880–2025 the Social Security Administration has recorded 5,383 people named Dock.
The Social Security Administration’s records begin in 1880, and Dock is already there in that first year — so the name is older than the record and these figures cannot date it. It has been recorded in 122 of the 146 years since.
The Social Security Administration has recorded 5,383 American births named Dock 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 931 are estimated to be alive today.
Dock 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.
Dock is new. It was not recorded at all a decade ago and averaged 5 births a year across 2021–2025.
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 Dock is a boy’s name — 0.0% of the 5,383 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 931 Americans named Dock are alive today — 17% of everyone ever recorded with the name. The median is 69 years old, and half are between 52 and 79.
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.
