Census
Eidan in the 2020 Census
The 2020 Census recorded 367 people with the first name Eidan, which placed it at #25,720 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 Eidan
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Eidan is Hispanic at 61.0%. The next largest groups are White (22.9%) and Asian/Pacific Islander (7.9%). 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 Eidan 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 Eidan at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Eidan
The name Eidan is of Irish origin, derived from the Gaelic word "aodh," which means "fire." It is a variation of the more common Irish name Aidan, which has been in use since the early medieval period.
The name first appeared in historical records around the 7th century AD, when it was borne by several Irish saints and scholars, most notably St. Aidan of Lindisfarne, an Irish monk who lived from 590 to 651 AD and played a significant role in the spread of Christianity in Northumbria, England.
One of the earliest recorded instances of the name Eidan can be found in the Annals of Ulster, a chronicle of medieval Irish history, where it is mentioned in reference to Eidan mac Findbairr, a king of Dalriada (modern-day Argyll, Scotland) who reigned in the late 7th century.
Throughout the Middle Ages, the name Eidan was relatively uncommon but was occasionally used by members of the Irish nobility and clergy. One notable bearer of the name was Eidan of Ferns, an Irish abbot and bishop who lived in the 8th century and was celebrated for his piety and learning.
In more recent times, the name Eidan has been borne by several individuals of note, including Eidan Gillen (born 1967), an Irish actor known for his roles in films such as "The Wire" and "Game of Thrones," and Eidan Byrne (1917-1998), an Irish footballer who played for several English clubs in the 1940s and 1950s.
Other notable bearers of the name include Eidan O'Connor (1832-1877), an Irish-American lawyer and politician who served as a member of the United States House of Representatives, and Eidan Kelly (born 1976), an Irish hurler who won several All-Ireland medals with the Kilkenny senior hurling team.
While the name Eidan has remained relatively rare throughout history, it has endured as a distinctly Irish name with a rich cultural heritage and a connection to the ancient Gaelic traditions of Ireland.

FAQ
Eidan: questions and answers
How many people in the U.S. are named Eidan?
Name Census puts the figure at roughly 705 living Americans. We arrive at this by taking every SSA birth registration for Eidan 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 486,176 US residents.
Is Eidan a common name?
We classify Eidan as "Very Rare". It ranks above 87.6% of all first names in the SSA dataset by living bearers. Across the full history of the data, 710 babies have been registered with this name.
When was Eidan most popular?
The single biggest year for Eidan was 2024, when 89 babies received the name. The fact that the average living Eidan is about 8 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
How common was Eidan in the 2020 Census?
The published 2020 Census first-name tables recorded 367 people with the name Eidan, or 0.12 per 100,000 residents. That placed it at #25,720 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 Eidan 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 Eidan?
In the 2020 Census sex table, Eidan leans strongly male. 347 people counted with this name were male (95.6%), compared with 16 female bearers (4.4%). 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 Eidan?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Eidan is Hispanic at 61.0%. The next largest groups are White (22.9%) and Asian/Pacific Islander (7.9%). 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 Eidan most often in the Census?
Hispanic is the largest reported group for people named Eidan in the 2020 Census, accounting for 61.0% (224 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 Eidan in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Eidan a male name?
Yes, 100.0% of people registered as Eidan 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 Eidan still being used today?
Yes. The SSA still recorded Eidan 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 Eidan 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.
