Kassius in the 2020 Census
The 2020 Census recorded 477 people with the first name Kassius, which placed it at #21,336 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 Kassius
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Kassius is Black at 39.4%. The next largest groups are White (22.0%) and Two or More Races (19.1%). 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 Kassius 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 Kassius at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Kassius
The given name Kassius is derived from the Latin name Cassius, which itself is likely of Etruscan origin. The Etruscans were an ancient civilization that predated the Romans in what is now central Italy. The name Cassius may be related to the Etruscan word "cassie", meaning "hollow" or "vain".
In ancient Roman times, Cassius was a common name among the patrician class. One of the earliest recorded uses of the name Cassius is in reference to Gaius Cassius Longinus, a Roman senator and leader of the assassination of Julius Caesar in 44 BC. The family name Cassius was also borne by several other notable Romans, including the 5th century philosopher Cassius Dio.
The variant spelling Kassius emerged later, likely influenced by the Greek rendering of the name as Κάσσιος (Kassios). This Hellenized form was used by some Romans and later adopted in various European languages.
One of the earliest known individuals with the name Kassius was Kassius the Patrician, a 6th century Byzantine senator who served under Emperor Justinian I. Another early bearer of the name was Kassius of Narni, a 6th century Italian monk and founder of the monastery of Santa Maria in Narni.
In the medieval period, the name Kassius was relatively uncommon but found occasional use in various parts of Europe. One notable figure was Kassius of Speyer, a 10th century Benedictine monk and scholar from Germany.
During the Renaissance, the name experienced a slight revival, particularly in Italy and Germany. This included figures such as Kassius Dux, a 16th century German humanist and poet, and Kassius Bernardinus, a 17th century Italian painter from Genoa.
Other notable individuals named Kassius throughout history include Kassius Burroughs, an 18th century American Revolutionary War soldier, and Kassius Clay, the birth name of the famous 20th century American boxer Muhammad Ali (1942-2016).

FAQ
Kassius: questions and answers
How many people in the U.S. are named Kassius?
Name Census puts the figure at roughly 1,126 living Americans. We arrive at this by taking every SSA birth registration for Kassius 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 304,400 US residents.
Is Kassius a common name?
We classify Kassius as "Rare". It ranks above 90.8% of all first names in the SSA dataset by living bearers. Across the full history of the data, 1,134 babies have been registered with this name.
When was Kassius most popular?
The single biggest year for Kassius was 2022, when 124 babies received the name. The fact that the average living Kassius 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 Kassius in the 2020 Census?
The published 2020 Census first-name tables recorded 477 people with the name Kassius, or 0.16 per 100,000 residents. That placed it at #21,336 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 Kassius 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 Kassius?
In the 2020 Census sex table, Kassius leans strongly male. 462 people counted with this name were male (96.9%), compared with 15 female bearers (3.1%). 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 Kassius?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Kassius is Black at 39.4%. The next largest groups are White (22.0%) and Two or More Races (19.1%). 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 Kassius most often in the Census?
Black is the largest reported group for people named Kassius in the 2020 Census, accounting for 39.4% (188 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 Kassius in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Kassius a male name?
Yes, 99.1% of people registered as Kassius 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 Kassius still being used today?
Yes. The SSA still recorded Kassius 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 Kassius 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.
