Census
Caitlan in the 2020 Census
The 2020 Census recorded 939 people with the first name Caitlan, which placed it at #13,019 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 Caitlan
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Caitlan is White at 79.9%. The next largest groups are Hispanic (9.1%) and Black (4.2%). 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 Caitlan 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 Caitlan at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Caitlan
The name Caitlan is a feminine variant of the Gaelic name Caitlín, which is derived from the Irish Gaedhilic name Caillín. This name traces its roots back to the Old Irish word "caille," meaning "veil" or "covering." Caillín was originally a pet form of the name Caillech, meaning "veiled one" or "nun."
The name Caitlín emerged in Ireland during the Middle Ages, around the 12th century. It was a popular name among Irish families, particularly in the western regions of the country. The spelling variations of Caitlan likely arose as an Anglicized version of the original Gaelic name, reflecting the influence of English language and culture on Irish naming traditions.
One of the earliest recorded instances of the name Caitlan can be found in the Annals of the Four Masters, a chronicle of medieval Irish history compiled in the 17th century. The annals mention a woman named Caitlín Ní Dhomhnaill, who lived in the 16th century and was the wife of the Lord of Tír Chonaill.
Throughout history, several notable individuals have borne the name Caitlan or its variants. One such figure was Caitlín Ní Uallacháin (c. 1680 - c. 1740), an Irish poet and noblewoman from County Limerick, renowned for her contributions to the Irish literary tradition.
Another notable Caitlan was Caitlín Bean Uí Chonaire (1856 - 1924), an Irish language scholar and educator who played a significant role in preserving and promoting the Irish language and culture in the late 19th and early 20th centuries.
In the realm of sports, Caitlan Bassett (born 1989) is an Australian netball player who has represented the Australian national team, the Diamonds, and has won multiple championships with various domestic and international teams.
Caitlan Gerard (born 1988) is an American actress known for her roles in various television series and films, including "Insidious: The Last Key" and "Daisy Jones & The Six."
Caitlan Coleman (born 1985) is an American woman who gained international attention in 2017 when she and her family were rescued from captivity by the Taliban in Afghanistan, where they had been held hostage for five years.
It's worth noting that while the name Caitlan has its origins in Irish culture, it has gained popularity and usage across various regions and cultures over time, particularly in English-speaking countries.

FAQ
Caitlan: questions and answers
How many people in the U.S. are named Caitlan?
Name Census puts the figure at roughly 1,010 living Americans. We arrive at this by taking every SSA birth registration for Caitlan 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 339,361 US residents.
Is Caitlan a common name?
We classify Caitlan as "Rare". It ranks above 90.2% of all first names in the SSA dataset by living bearers. Across the full history of the data, 1,047 babies have been registered with this name.
When was Caitlan most popular?
The single biggest year for Caitlan was 1990, when 88 babies received the name. The fact that the average living Caitlan is about 33 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
How common was Caitlan in the 2020 Census?
The published 2020 Census first-name tables recorded 939 people with the name Caitlan, or 0.31 per 100,000 residents. That placed it at #13,019 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 Caitlan 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 Caitlan?
In the 2020 Census sex table, Caitlan appears almost entirely female. Of the 940 people counted with this name, 99.8% were female and only a very small share were male. 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 Caitlan?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Caitlan is White at 79.9%. The next largest groups are Hispanic (9.1%) and Black (4.2%). 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 Caitlan most often in the Census?
White is the largest reported group for people named Caitlan in the 2020 Census, accounting for 79.9% (750 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 Caitlan in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Caitlan a female name?
Yes, 100.0% of people registered as Caitlan 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 Caitlan still being used today?
Yes. The SSA still recorded Caitlan 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 Caitlan 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.
