Milli in the 2020 Census
The 2020 Census recorded 560 people with the first name Milli, which placed it at #19,065 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 Milli
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Milli is White at 49.6%. The next largest groups are Hispanic (23.2%) and Asian/Pacific Islander (12.5%). 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 Milli 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 Milli at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Milli
The name Milli originated from the Latin word "millia," which means "thousands." It was initially a term used to denote distance measurements and later became a name in various cultures.
In ancient Rome, millia was a unit of measurement representing a thousand paces or approximately one Roman mile. This term was often used in military contexts and to describe the distances between locations on Roman roads and trade routes.
The earliest recorded use of Milli as a personal name can be traced back to the Middle Ages in Europe. During this period, it was not uncommon for names to be derived from occupations, locations, or descriptive terms. Milli likely emerged as a name for individuals who lived or worked near a milestone or were involved in distance measurement or surveying.
One of the earliest known historical figures with the name Milli was Milli of Rheims, a 12th-century Benedictine monk and scholar from the Abbey of Saint-Remi in Rheims, France. He is known for his writings on theology and philosophy.
In the 16th century, Milli Frilli was an Italian painter and engraver active in the Renaissance era. She is notable for being one of the few female artists recognized during that time.
During the 19th century, Milli Bacher was an Austrian painter and illustrator known for her portraits and genre scenes. She was born in 1844 and lived until 1908.
In the early 20th century, Milli Jasmin was a German silent film actress who appeared in numerous films during the 1910s and 1920s. She was born in 1888 and passed away in 1957.
Another notable figure with the name Milli was Milli Trilla, an Austrian writer and journalist who lived from 1904 to 1989. She published several novels and works of non-fiction, often exploring themes of love, relationships, and societal issues.
While the name Milli is not as common today as it once was, its historical roots can be traced back to ancient Roman measurements and the widespread use of Latin throughout Europe during the Middle Ages and Renaissance periods.

FAQ
Milli: questions and answers
How many people in the U.S. are named Milli?
Name Census puts the figure at roughly 418 living Americans. We arrive at this by taking every SSA birth registration for Milli 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 819,986 US residents.
Is Milli a common name?
We classify Milli as "Very Rare". It ranks above 82.8% of all first names in the SSA dataset by living bearers. Across the full history of the data, 421 babies have been registered with this name.
When was Milli most popular?
The single biggest year for Milli was 2022, when 39 babies received the name. The fact that the average living Milli is about 10 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
How common was Milli in the 2020 Census?
The published 2020 Census first-name tables recorded 560 people with the name Milli, or 0.19 per 100,000 residents. That placed it at #19,065 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 Milli 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 Milli?
In the 2020 Census sex table, Milli leans strongly female. 544 people counted with this name were female (98.0%), compared with 11 male bearers (2.0%). 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 Milli?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Milli is White at 49.6%. The next largest groups are Hispanic (23.2%) and Asian/Pacific Islander (12.5%). 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 Milli most often in the Census?
White is the largest reported group for people named Milli in the 2020 Census, accounting for 49.6% (278 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 Milli in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Milli a female name?
Yes, 100.0% of people registered as Milli 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 Milli still being used today?
Yes. The SSA still recorded Milli 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 Milli 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.
