Census
Dailin in the 2020 Census
The 2020 Census recorded 436 people with the first name Dailin, which placed it at #22,736 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.

Ancestry and ethnicity for Dailin
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Dailin is Hispanic at 72.7%. The next largest groups are Black (9.6%) and Asian/Pacific Islander (9.6%). 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 Dailin 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 Dailin at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Dailin
The given name Dailin originates from the ancient Irish language and culture, with its roots tracing back to the 5th century AD. It is derived from the Old Irish word "dail," which means "meeting" or "assembly," combined with the diminutive suffix "-in," signifying endearment or smallness. This suggests that the name Dailin may have initially referred to a small gathering or a cherished assembly.
Dailin is believed to have been a relatively common name among the Gaelic-speaking populations of Ireland during the medieval period. While no specific historical references to individuals bearing this name have been found in ancient texts or religious scriptures, it is likely that the name was used within local communities and oral traditions.
One of the earliest recorded examples of the name Dailin can be found in the Annals of Ulster, a chronicle of medieval Irish history compiled by monks in the 15th century. The entry from the year 1048 mentions a certain "Dailin mac Goffraidh," which translates to "Dailin, son of Godfrey."
Throughout history, there have been several notable individuals who bore the name Dailin, although information about their lives and accomplishments is scarce. One such figure was Dailin Ó Conchobhair (1190-1244), a minor Irish king who ruled over the territory of Uí Failghe, now part of County Offaly, Ireland. Another was Dailin Mac Murchadha (1215-1279), a prominent member of the Mac Murchadha dynasty, which dominated parts of County Wexford during the same period.
In the 14th century, a renowned Irish poet and bard named Dailin Ó Muireadhaigh (1310-1380) gained recognition for his skilled compositions and performances in the bardic tradition. His works, though largely lost to time, were said to have celebrated the exploits of various Irish chieftains and nobility.
Moving forward to the 16th century, Dailin Ó Ceallaigh (1525-1590) was a respected Irish scholar and historian who authored several manuscripts on the genealogies and histories of various Irish clans and territories.
Finally, in the 18th century, Dailin Ó Briain (1710-1782) was a notable Irish harpist and musician who helped preserve and promote the traditional Irish harp music during a period when it was in decline.
It is important to note that due to the scarcity of historical records and the variations in spelling and transliteration, some of these individuals may have had slightly different spellings or variations of the name Dailin.

FAQ
Dailin: questions and answers
How many people in the U.S. are named Dailin?
Name Census puts the figure at roughly 162 living Americans. We arrive at this by taking every SSA birth registration for Dailin 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 2,115,768 US residents.
Is Dailin a common name?
We classify Dailin as "Very Rare". It ranks above 71.4% of all first names in the SSA dataset by living bearers. Across the full history of the data, 164 babies have been registered with this name.
When was Dailin most popular?
The single biggest year for Dailin was 2008, when 14 babies received the name. The fact that the average living Dailin is about 15 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
How common was Dailin in the 2020 Census?
The published 2020 Census first-name tables recorded 436 people with the name Dailin, or 0.14 per 100,000 residents. That placed it at #22,736 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 Dailin 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 Dailin?
In the 2020 Census sex table, Dailin leans strongly female. 350 people counted with this name were female (80.6%), compared with 84 male bearers (19.4%). 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 Dailin?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Dailin is Hispanic at 72.7%. The next largest groups are Black (9.6%) and Asian/Pacific Islander (9.6%). 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 Dailin most often in the Census?
Hispanic is the largest reported group for people named Dailin in the 2020 Census, accounting for 72.7% (317 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 Dailin in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Dailin a female name?
Yes, 84.1% of people registered as Dailin in the SSA data are female. 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 Dailin still being used today?
Yes. The SSA still recorded Dailin 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 Dailin 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.
