Origin
Meaning and history of Dominicus
The given name Dominicus has its origins in the Latin language, deriving from the word "dominus," which means "lord" or "master." It emerged during the Roman Empire, with the earliest recorded instances dating back to the 3rd and 4th centuries AD.
One of the most notable historical references to the name Dominicus can be found in the life of St. Dominic, the founder of the Dominican Order of Preachers. Born in 1170 in Caleruega, Spain, St. Dominic played a significant role in the spread of Christianity and the fight against heresy during the Middle Ages.
Another prominent figure bearing the name Dominicus was Pope St. Dominic of Guzman (c. 1170-1221), who is revered as a patron saint of astronomers and the Catholic Church. His efforts in establishing the Dominican Order and promoting education significantly impacted the religious landscape of the time.
In the realm of literature, the name Dominicus appears in the works of Cicero, a Roman philosopher and statesman who lived from 106 BC to 43 BC. Cicero's writings, particularly his philosophical treatises, have had a lasting influence on Western thought and continue to be studied and admired.
During the Renaissance period, Dominicus Gundissalinus (c. 1115-1190) was a renowned philosopher and translator who played a crucial role in introducing Arabic and Greek philosophical works to the Latin West. His translations and commentaries facilitated the exchange of ideas between different cultures and contributed to the intellectual revival of the time.
In the field of science, Dominicus Arumaeus (c. 1579-1637) was a Dutch astronomer and mathematician who made significant contributions to the study of comets and the development of astronomical instruments. His works, such as "Dissertatio de Cometis" (Dissertation on Comets), provided valuable insights into celestial phenomena.
The name Dominicus has a rich history, spanning various domains, including religion, literature, philosophy, and science. Its Latin origins and associations with notable figures throughout history have imbued it with a sense of reverence and intellectual significance.

FAQ
Dominicus: questions and answers
How many people in the U.S. are named Dominicus?
Name Census puts the figure at roughly 5 living Americans. We arrive at this by taking every SSA birth registration for Dominicus 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 68,550,868 US residents.
Is Dominicus a common name?
We classify Dominicus as "Very Rare". It ranks above 18.2% of all first names in the SSA dataset by living bearers. Across the full history of the data, 5 babies have been registered with this name.
When was Dominicus most popular?
The single biggest year for Dominicus was 2021, when 5 babies received the name. The fact that the average living Dominicus is about 5 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
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 Dominicus in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Dominicus a male name?
Yes, 100.0% of people registered as Dominicus 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 Dominicus still being used today?
Yes. The SSA still recorded Dominicus 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 Dominicus 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. You can read the full calculation on our methodology page.
Does every first name have Census demographic data?
No. The public Census first-name release only covers names that met the Bureau's publication rules, so many rarer names in the SSA files do not have a published Census demographic snapshot. In those cases, the page still shows the SSA trend, gender history, and state data.
