Census
Jullien in the 2020 Census
The 2020 Census recorded 263 people with the first name Jullien, which placed it at #32,158 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 Jullien
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Jullien is Hispanic at 46.8%. The next largest groups are White (24.7%) and Black (16.7%). 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 Jullien 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 Jullien at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Jullien
The name Jullien is a French variant of the Latin name Julius, which was derived from the ancient Roman family name Julii. Its origins can be traced back to the 7th century BCE when the Julii clan emerged as a prominent patrician family in ancient Rome.
The name Julius is believed to have originated from the Latin word "ioulos," meaning "downy-bearded." It was a common practice among ancient Romans to adopt surnames based on physical characteristics or accomplishments. The Julii clan may have been known for their distinctive beards, leading to the adoption of this name.
One of the most famous historical figures bearing the name Julius was Gaius Julius Caesar, the celebrated Roman military leader, statesman, and author, who lived from 100 BCE to 44 BCE. His legacy and impact on Roman history and the Western world have made the name Julius a renowned and enduring one.
In the early Christian era, the name Julius gained further significance as it was borne by several early popes and saints. Pope Julius I, who reigned from 337 to 352 CE, was a notable figure who helped establish the primacy of the Roman Church. Saint Julius the Veteran, a 4th-century martyr, was also a significant figure in early Christianity.
Throughout the Middle Ages and Renaissance, the name Jullien, along with its various spellings such as Julien and Julianus, remained in use across Europe. Notable figures include Julien de Toulouse, a 12th-century French poet, and Julien de Vénetiis, a 13th-century French philosopher and theologian.
In the 18th century, Julien de Parme, a French composer and music theorist, made significant contributions to the development of music theory and education. Another notable figure was Julien Offray de La Mettrie, a French physician and philosopher, who lived from 1709 to 1751 and was known for his materialist writings.
During the 19th century, Julien Viaud, better known by his pen name Pierre Loti, was a French novelist and naval officer who gained fame for his exotic and semi-autobiographical novels set in various parts of the world, including Turkey and Polynesia. He lived from 1850 to 1923.

FAQ
Jullien: questions and answers
How many people in the U.S. are named Jullien?
Name Census puts the figure at roughly 297 living Americans. We arrive at this by taking every SSA birth registration for Jullien 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 1,154,055 US residents.
Is Jullien a common name?
We classify Jullien as "Very Rare". It ranks above 79.1% of all first names in the SSA dataset by living bearers. Across the full history of the data, 300 babies have been registered with this name.
When was Jullien most popular?
The single biggest year for Jullien was 2009, when 27 babies received the name. The fact that the average living Jullien 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 Jullien in the 2020 Census?
The published 2020 Census first-name tables recorded 263 people with the name Jullien, or 0.09 per 100,000 residents. That placed it at #32,158 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 Jullien 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 Jullien?
In the 2020 Census sex table, Jullien leans strongly male. 248 people counted with this name were male (93.6%), compared with 17 female bearers (6.4%). 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 Jullien?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Jullien is Hispanic at 46.8%. The next largest groups are White (24.7%) and Black (16.7%). 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 Jullien most often in the Census?
Hispanic is the largest reported group for people named Jullien in the 2020 Census, accounting for 46.8% (123 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 Jullien in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Jullien a male name?
Yes, 100.0% of people registered as Jullien 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 Jullien still being used today?
Yes. The SSA still recorded Jullien 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 Jullien 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.
