Cassi in the 2020 Census
The 2020 Census recorded 2,381 people with the first name Cassi, which placed it at #6,671 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 Cassi
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Cassi is White at 83.3%. The next largest groups are Hispanic (5.3%) and Black (5.0%). 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 Cassi 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 Cassi at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Cassi
The name Cassi finds its origins in the ancient Roman civilization, derived from the Latin word "Cassius," which was a Roman family name. The etymology of Cassius can be traced back to the Latin word "cassus," meaning "empty" or "vain."
During the Roman era, the name Cassius was borne by several notable figures, including Gaius Cassius Longinus, one of the primary conspirators in the assassination of Julius Caesar in 44 BC. This historical event was immortalized in Shakespeare's play, "Julius Caesar," where Cassius played a pivotal role.
Another prominent individual with the name Cassius was Avidius Cassius, a Roman military commander who led a short-lived revolt against Emperor Marcus Aurelius in 175 AD. Despite its association with rebellion, the name Cassius remained in use throughout the Roman Empire.
In the early Christian era, the name Cassius gained popularity among the faithful, as it was believed to be derived from the Latin word "castus," meaning "pure" or "chaste." One of the earliest recorded examples of the name Cassi is Saint Cassia, a Christian martyr who lived in the 3rd century AD.
During the Middle Ages, the name Cassi was relatively uncommon, but it resurfaced in the Renaissance period. One notable figure from this era was Cassia Truchis, an Italian poet and writer who lived in the 16th century.
In more recent history, the name Cassi has been borne by several notable individuals, including:
1. Cassi Abranavan (1912-1992), an American actress and dancer known for her roles in Broadway musicals.
2. Cassi Patton Lupton (1923-2018), an American philanthropist and co-founder of the Virginia Museum of Fine Arts.
3. Cassi Stephens (born 1987), an American singer-songwriter and former member of the country music group Gloriana.
4. Cassi Thomson (born 1994), an Australian actress known for her role in the television series "Revenge."
5. Cassi Amber (born 1986), an American model and former professional wrestler.
While the name Cassi has its roots in ancient Roman culture, it has transcended time and geography, finding new meanings and associations throughout history. Its enduring presence reflects the versatility and timelessness of this unique name.

FAQ
Cassi: questions and answers
How many people in the U.S. are named Cassi?
Name Census puts the figure at roughly 2,233 living Americans. We arrive at this by taking every SSA birth registration for Cassi 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 153,495 US residents.
Is Cassi a common name?
We classify Cassi as "Rare". It ranks above 94.1% of all first names in the SSA dataset by living bearers. Across the full history of the data, 2,356 babies have been registered with this name.
When was Cassi most popular?
The single biggest year for Cassi was 1982, when 126 babies received the name. The fact that the average living Cassi is about 36 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
How common was Cassi in the 2020 Census?
The published 2020 Census first-name tables recorded 2,381 people with the name Cassi, or 0.79 per 100,000 residents. That placed it at #6,671 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 Cassi 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 Cassi?
In the 2020 Census sex table, Cassi appears almost entirely female. Of the 2,375 people counted with this name, 99.6% 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 Cassi?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Cassi is White at 83.3%. The next largest groups are Hispanic (5.3%) and Black (5.0%). 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 Cassi most often in the Census?
White is the largest reported group for people named Cassi in the 2020 Census, accounting for 83.3% (1,983 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 Cassi in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Cassi a female name?
Yes, 100.0% of people registered as Cassi 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 Cassi still being used today?
Yes. The SSA still recorded Cassi 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 Cassi 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.
