Tadarius in the 2020 Census
The 2020 Census recorded 277 people with the first name Tadarius, which placed it at #31,090 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.

The bar chart below shows how people with the first name Tadarius 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 Tadarius at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Tadarius
The name Tadarius has its origins in the ancient Etruscan language, dating back to the 8th century BCE. It is believed to have been derived from the Etruscan word "tader," which meant "warrior" or "brave one." The name was popular among the Etruscan nobility and aristocracy, who prided themselves on their military prowess and valor.
One of the earliest recorded instances of the name Tadarius can be found in the Etruscan inscriptions discovered in the city of Cerveteri, near modern-day Rome. These inscriptions, dating back to the 6th century BCE, mention a prominent Etruscan leader by the name of Tadarius, who was revered for his leadership in battles against neighboring tribes.
As the Etruscan civilization gradually became assimilated into the Roman culture, the name Tadarius began to appear in Roman historical records as well. One notable figure bearing this name was Tadarius Maximus, a Roman general who lived in the 2nd century CE and played a crucial role in the Roman conquest of Britannia.
During the Middle Ages, the name Tadarius enjoyed a resurgence in popularity among the noble families of Italy and France. A famous bearer of the name was Tadarius de Montfort, a French nobleman and crusader who participated in the Fourth Crusade and the Albigensian Crusade in the 13th century.
In the Renaissance era, the name Tadarius was associated with several prominent figures in the arts and literature. One such individual was Tadarius Tasso, an Italian poet and playwright who lived from 1544 to 1595 and is best known for his epic poem "Gerusalemme Liberata."
Another notable figure with this name was Tadarius Vinci, an Italian architect and engineer who lived from 1652 to 1728. He is renowned for his innovative designs and contributions to the field of hydraulic engineering, having designed several intricate water systems and fountains throughout Italy.
While the name Tadarius has since fallen out of common usage, it remains a testament to the rich cultural heritage and historical significance of its Etruscan roots, serving as a reminder of the enduring legacy of ancient civilizations.

FAQ
Tadarius: questions and answers
How many people in the U.S. are named Tadarius?
Name Census puts the figure at roughly 382 living Americans. We arrive at this by taking every SSA birth registration for Tadarius 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 897,263 US residents.
Is Tadarius a common name?
We classify Tadarius as "Very Rare". It ranks above 81.9% of all first names in the SSA dataset by living bearers. Across the full history of the data, 389 babies have been registered with this name.
When was Tadarius most popular?
The single biggest year for Tadarius was 2001, when 25 babies received the name. The fact that the average living Tadarius is about 25 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
How common was Tadarius in the 2020 Census?
The published 2020 Census first-name tables recorded 277 people with the name Tadarius, or 0.09 per 100,000 residents. That placed it at #31,090 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 Tadarius 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 Tadarius?
In the 2020 Census sex table, Tadarius appears almost entirely male. Of the 279 people counted with this name, 99.6% were male and only a very small share were female. 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 Tadarius?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Tadarius is Black at 95.7%. The next largest groups are White (2.5%) and Hispanic (1.1%). 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 Tadarius most often in the Census?
Black is the largest reported group for people named Tadarius in the 2020 Census, accounting for 95.7% (265 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 Tadarius in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Tadarius a male name?
Yes, 100.0% of people registered as Tadarius 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 Tadarius still being used today?
Yes. The SSA still recorded Tadarius 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 Tadarius 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.
