How old is the name Mcarthur?
Mcarthur first appears in Social Security Administration records in 1912, which makes it about 113 years old as a recorded American name. It has been recorded in 80 of the 114 years since.
How many people are named Mcarthur?
The Social Security Administration has recorded 2,275 American births named Mcarthur 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 1,497 are estimated to be alive today.
How many babies were named Mcarthur in 2025?
Mcarthur 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.
Is Mcarthur getting more or less popular?
Mcarthur is too rare for a direction to mean much. It averaged 7 births a year across 2021–2025 against 8 a year a decade earlier — at these counts a single baby moves the percentage, and any year under five births is withheld at source.
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.
Is Mcarthur a boy’s or a girl’s name?
Across the whole record Mcarthur is a boy’s name — 0.0% of the 2,275 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.
How old is someone named Mcarthur?
Roughly 1,497 Americans named Mcarthur are alive today — 66% of everyone ever recorded with the name. The median is 64 years old, and half are between 48 and 79. 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.
