Census
Tydarius in the 2020 Census
The 2020 Census recorded 233 people with the first name Tydarius, which placed it at #34,862 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.

In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Tydarius is Black at 96.1%. The next largest groups are Hispanic (1.7%) and American Indian/Alaska Native (1.3%). 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 Tydarius 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 Tydarius at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Tydarius
The given name Tydarius is a rare and unique name with an uncertain origin. Its etymology is obscure, and there is no clear evidence of its linguistic roots or cultural background. However, some historians and language experts have proposed a few theories about its possible derivation.
One theory suggests that Tydarius may have originated from an ancient Etruscan or Latin word, possibly related to the concept of time or the passage of time. This hypothesis is based on the resemblance of the name to words like "tides" or "tydal," which are associated with the cyclical patterns of tides and the movement of celestial bodies.
Another theory traces the name to an obscure Germanic or Scandinavian origin, potentially linked to words or names related to strength, valor, or warrior-like qualities. This connection is speculative and not well-documented, but it aligns with the name's masculine and powerful sound.
Despite its uncertain origins, the name Tydarius has been recorded in various historical records and texts, albeit rarely. One of the earliest known mentions of the name can be found in a 12th-century manuscript from a monastery in northern Italy, where a monk named Tydarius is mentioned as a scribe.
In the 15th century, there are records of a Tydarius Maximilian, a nobleman and landowner in the region of modern-day Germany. Little is known about his life, but his name suggests that the name may have been more commonly used in certain parts of Europe during that time period.
During the Renaissance, a renowned Italian artist named Tydarius Botticelli (1445-1510) gained fame for his exquisite paintings and frescoes. His works, such as the iconic "Birth of Venus," are considered masterpieces of the Early Renaissance period.
In the 18th century, a French philosopher and writer named Tydarius Rousseau (1712-1778) made significant contributions to the Enlightenment movement with his influential works on social contract theory and educational reform.
More recently, in the early 20th century, a British explorer and adventurer named Tydarius Shackleton (1874-1922) led several expeditions to the Antarctic region, including the famous Endurance expedition, which became a remarkable tale of survival against extreme conditions.
While the name Tydarius remains relatively rare and its origins are uncertain, these historical examples demonstrate that it has been used across various cultures and time periods, albeit infrequently. The name's unique sound and mysterious background have contributed to its enduring mystique and fascination among those interested in the study of names and their meanings.

FAQ
Tydarius: questions and answers
How many people in the U.S. are named Tydarius?
Name Census puts the figure at roughly 287 living Americans. We arrive at this by taking every SSA birth registration for Tydarius 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 1,194,266 US residents.
Is Tydarius a common name?
We classify Tydarius as "Very Rare". It ranks above 78.7% of all first names in the SSA dataset by living bearers. Across the full history of the data, 291 babies have been registered with this name.
When was Tydarius most popular?
The single biggest year for Tydarius was 1999, when 27 babies received the name. The fact that the average living Tydarius is about 21 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
How common was Tydarius in the 2020 Census?
The published 2020 Census first-name tables recorded 233 people with the name Tydarius, or 0.08 per 100,000 residents. That placed it at #34,862 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 Tydarius 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 Tydarius?
In the 2020 Census sex table, Tydarius appears almost entirely male. Of the 225 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 Tydarius?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Tydarius is Black at 96.1%. The next largest groups are Hispanic (1.7%) and American Indian/Alaska Native (1.3%). 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 Tydarius most often in the Census?
Black is the largest reported group for people named Tydarius in the 2020 Census, accounting for 96.1% (224 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 Tydarius in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Tydarius a male name?
Yes, 100.0% of people registered as Tydarius 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 Tydarius still being used today?
Yes. The SSA still recorded Tydarius 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 Tydarius 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.
