Census
Gailen in the 2020 Census
The 2020 Census recorded 266 people with the first name Gailen, which placed it at #31,950 in the published first-name tables. This is a snapshot of people who already had the name at the time of the Census.
The SSA sections elsewhere on this page answer a different question: how often parents gave the name to babies over time. The "people living today" figure on this page is different again: it is a current estimate built from SSA birth records and age-based survival rates, so the two numbers are not expected to match exactly.

Demographics
Ancestry and ethnicity for Gailen
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Gailen is White at 84.6%. The next largest groups are Black (9.8%) and Hispanic (2.6%). These figures describe the people who had the name in 2020, not any inherent property of the name itself.
The bar chart below shows how people with the first name Gailen described their own race and ethnicity on the 2020 Census form. The Census Bureau groups responses into six broad categories: White, Black or African American, Hispanic or Latino, Asian and Pacific Islander, American Indian and Alaska Native, and Two or More Races. When a category has too few respondents for a given name, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.
Percentages are shown so the breakdown is easy to read across every published category. Because the 2020 Census first-name file also includes raw headcounts for each group, Name Census can show those alongside the percentages in the legend and hover tooltip.
Keep in mind that these are self-reported numbers. A first name does not determine a person's race or ethnicity, and the distribution you see here reflects the specific population who happened to carry the name Gailen at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Gailen
The given name Gailen has its origins in the Gaelic language, which was spoken in medieval times across parts of Scotland, Ireland, and the Isle of Man. It is derived from the Old Irish word "gailén," which means "little storm" or "little gale." This suggests that the name may have originally been used to describe a person with a fiery or tempestuous personality.
Gailen is a variant spelling of the more common Irish name "Galen," which shares the same root. The name has been in use for centuries, with some of the earliest recorded instances dating back to the 12th century in Ireland.
In ancient Irish mythology, there are references to a figure named Gailén mac Lughaidh, who was a legendary king of Connacht in the 5th century AD. This suggests that the name may have been associated with royalty or nobility in its early usage.
One of the earliest known historical figures to bear the name Gailen was Gailen mac Cennétig, a 9th-century Scottish king who ruled the kingdom of Dál Riata. This indicates that the name was also used among the Gaelic-speaking populations of what is now modern-day Scotland.
Another notable figure named Gailen was Gailen of Leinster, an Irish poet and scholar who lived in the 12th century. He is known for his work in preserving and transcribing ancient Irish manuscripts and literary traditions.
In the 14th century, there was a Gailen Mac Wattin, who was a Scottish chieftain and leader of the Clan MacQueen. He was involved in various conflicts and battles during the Wars of Scottish Independence against the English.
Moving forward in time, there was a Gailen O'Donovan, an Irish soldier who fought in the Irish Confederate Wars of the 17th century. He was a member of the O'Donovan clan and served as a captain in the Irish Confederate forces.
While the name Gailen has fallen out of widespread use in modern times, it remains a part of the rich cultural heritage and history of the Gaelic-speaking peoples of Ireland and Scotland.

FAQ
Gailen: questions and answers
How many people in the U.S. are named Gailen?
Name Census puts the figure at roughly 123 living Americans. We arrive at this by taking every SSA birth registration for Gailen going back to 1880 and adjusting each cohort for expected survival using CDC actuarial life tables. The result is an age-weighted living-bearer count, not a raw birth total. That works out to about 1 in 2,786,621 US residents.
Is Gailen a common name?
We classify Gailen as "Very Rare". It ranks above 67.5% of all first names in the SSA dataset by living bearers. Across the full history of the data, 256 babies have been registered with this name.
When was Gailen most popular?
The single biggest year for Gailen was 1951, when 15 babies received the name. The fact that the average living Gailen is about 74 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
How common was Gailen in the 2020 Census?
The published 2020 Census first-name tables recorded 266 people with the name Gailen, or 0.09 per 100,000 residents. That placed it at #31,950 in the national Census ranking for first names.
Why is the Census count different from the living estimate?
Because they measure different things. The Census figure is a count of people who had the name Gailen in 2020. The living estimate aims to answer a current question instead: how many people with the name are alive today, based on SSA birth records and age-based survival rates. Since one number is a 2020 snapshot and the other is a present-day estimate, they are not expected to be identical.
What does the Census say about the gender split for Gailen?
The 2020 Census sex table shows Gailen on both sides of the split. Of the 267 people counted with this name, 194 were male (72.7%) and 73 were female (27.3%). The Census view is a snapshot of people living with the name in 2020, while the SSA section above tracks births across time.
What does the Census say about the background of people named Gailen?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Gailen is White at 84.6%. The next largest groups are Black (9.8%) and Hispanic (2.6%). These figures describe the people who had the name in 2020, not any inherent property of the name itself. The percentages in the chart above come from self-reported race and Hispanic-origin responses in the 2020 Census.
Which group reports the name Gailen most often in the Census?
White is the largest reported group for people named Gailen in the 2020 Census, accounting for 84.6% (225 people in the published table).
Why can the Census sex total and race total differ slightly?
The Census Bureau published separate 2020 tables for sex and for race/Hispanic origin, and the released figures can differ slightly because of privacy protection in the public files. That is why this page treats the gender section and the race/origin section as two related snapshots instead of forcing them into one identical total.
Does every first name have Census demographic data?
No. The public Census first-name release only includes names that met the Bureau's publication rules, so many rarer names in the SSA files have no Census demographic snapshot. When that happens, the SSA trend, gender history, and state sections still appear, but the 2020 Census demographic sections are omitted.
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 Gailen in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Gailen a male name?
Yes, 97.7% of people registered as Gailen in the SSA data are male. You can see the full per-sex comparison in the gender distribution section above, which includes the latest year rank, birth count, and peak year for each sex.
Is Gailen still being used today?
Yes. The SSA still recorded Gailen 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 Gailen 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.
