Census
Dionis in the 2020 Census
The 2020 Census recorded 457 people with the first name Dionis, which placed it at #21,974 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 Dionis
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Dionis is Hispanic at 72.0%. The next largest groups are White (23.0%) and Black (2.6%). 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 Dionis 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 Dionis at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Dionis
The name Dionis is derived from the ancient Greek name Dionysios, which is ultimately rooted in the name of the Greek god Dionysus, the god of wine, vegetation, pleasure, festivity, and madness. Dionysios was a relatively common personal name among the ancient Greeks, particularly in the classical period from the 5th to 4th century BCE.
The name Dionysios is composed of the elements "Dio" meaning "divine" or "god", and "Nysos" meaning "Nysa", which was a mythological location associated with the birth and upbringing of the god Dionysus. The name can be interpreted to mean "son of Zeus" or "divine son", reflecting the mythological tradition that Dionysus was the son of Zeus and the mortal woman Semele.
One of the earliest recorded instances of the name Dionysios dates back to the 6th century BCE when it was borne by a Greek tyrant of Syracuse, Dionysios I (430-367 BCE), who ruled from 405 to 367 BCE. Another notable historical figure with this name was Dionysios of Halicarnassus (c. 60 BCE - after 7 BCE), a Greek historian and teacher of rhetoric who lived in the 1st century BCE.
During the Middle Ages, the name Dionysios underwent various transformations and adaptations in different languages and cultures. In Latin, it became Dionysius, and this form was adopted by several early Christian saints and martyrs, such as Saint Dionysius the Areopagite (c. 1st century CE) and Saint Dionysius of Paris (c. 3rd century CE), the patron saint of France.
The French form of the name, Denis, became popular during the medieval period, and several French kings bore this name, including Denis I (c. 629-638 CE), Denis the Little (c. 470-544 CE), a Scythian monk known for his work on canon law, and Denis Diderot (1713-1784 CE), the famous French philosopher and writer of the Enlightenment period.
The name Dionis is a variant spelling that emerged in various European languages, including Spanish and Portuguese. Notable historical figures with this spelling include Dionis Castell (c. 1595-1644), a Welsh mathematician and lawyer, and Dionis Zamudio (fl. 16th century), a Spanish navigator and explorer who participated in the Spanish conquest of the Philippines.

FAQ
Dionis: questions and answers
How many people in the U.S. are named Dionis?
Name Census puts the figure at roughly 115 living Americans. We arrive at this by taking every SSA birth registration for Dionis 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 2,980,473 US residents.
Is Dionis a common name?
We classify Dionis as "Very Rare". It ranks above 66.6% of all first names in the SSA dataset by living bearers. Across the full history of the data, 117 babies have been registered with this name.
When was Dionis most popular?
The single biggest year for Dionis was 2004, when 9 babies received the name. The fact that the average living Dionis is about 23 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
How common was Dionis in the 2020 Census?
The published 2020 Census first-name tables recorded 457 people with the name Dionis, or 0.15 per 100,000 residents. That placed it at #21,974 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 Dionis 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 Dionis?
In the 2020 Census sex table, Dionis leans strongly male. 373 people counted with this name were male (81.3%), compared with 86 female bearers (18.7%). 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 Dionis?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Dionis is Hispanic at 72.0%. The next largest groups are White (23.0%) and Black (2.6%). 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 Dionis most often in the Census?
Hispanic is the largest reported group for people named Dionis in the 2020 Census, accounting for 72.0% (329 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 Dionis in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Dionis a male name?
Yes, 100.0% of people registered as Dionis 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 Dionis still being used today?
Yes. The SSA still recorded Dionis 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 Dionis 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.
