Sean is an Irish name with roots tracing back to the ancient Gaelic name Seán, which is derived from the word "sean" meaning "old" or "ancient."

FAQ
Seanjohn: questions and answers
How many people in the U.S. are named Seanjohn?
Name Census puts the figure at roughly 5 living Americans. We arrive at this by taking every SSA birth registration for Seanjohn going back to 1880 and adjusting each cohort for expected survival using CDC actuarial life tables.

We classify Seanjohn as "Very Rare". It ranks above 18.2% of all first names in the SSA dataset by living bearers. Across the full history of the data, 5 babies have been registered with this name.
When was Seanjohn most popular?
The single biggest year for Seanjohn was 2009, when 5 babies received the name. The fact that the average living Seanjohn is about 17 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
What does the SSA popularity chart show?
The chart tracks births, not the number of people alive with the name today. Each point shows how many babies were given the name Seanjohn in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Seanjohn a male name?

Is Seanjohn still being used today?
Yes. The SSA still recorded Seanjohn in 2024, and the page above shows its latest-year rank where available. A name can be well past its peak and still remain in steady use, especially if it built up a large population over earlier decades.
Why can a name have a lot of living bearers even if it is not trendy now?
Because living-bearer counts and current baby-name popularity measure different things. A name like Seanjohn can build up a very large population over many decades, even if fewer parents are choosing it now than they did at its peak.
Where does this data come from?
First-name figures come from the Social Security Administration's national baby name files, which cover every name on a birth certificate from 1880 to 2024. Living-bearer estimates layer in CDC actuarial life tables broken out by sex to account for mortality. The population baseline (342,754,338) is the Census Bureau's latest national estimate. You can read the full calculation on our methodology page.
Does every first name have Census demographic data?
No. The public Census first-name release only covers names that met the Bureau's publication rules, so many rarer names in the SSA files do not have a published Census demographic snapshot. In those cases, the page still shows the SSA trend, gender history, and state data.
