Census
Ilario in the 2020 Census
The 2020 Census recorded 491 people with the first name Ilario, which placed it at #20,884 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 Ilario
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Ilario is Hispanic at 73.3%. The next largest groups are White (22.0%) and American Indian/Alaska Native (1.8%). 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 Ilario 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 Ilario at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Ilario
The name Ilario is an Italian masculine name derived from the Latin name Hilarius, which itself is derived from the Latin word "hilaris" meaning "cheerful" or "merry." The name can be traced back to ancient Rome and was likely used as a personal name or cognomen (surname) during that time period.
While the exact origin of the name Hilarius is uncertain, it is believed to have been used as a personal name or cognomen in ancient Rome, possibly given to individuals with a particularly cheerful or joyful disposition. The name may have also been associated with the Roman festival of Hilaria, which celebrated the vernal equinox and the beginning of spring.
One of the earliest recorded examples of the name Hilarius can be found in the writings of the Roman historian Tacitus, who mentioned a man named Quintus Hilarius living during the 1st century AD. In the 4th century AD, there was a famous bishop of Poitiers named Hilarius, who is now venerated as a saint in the Catholic Church.
Throughout history, there have been several notable individuals named Ilario or its variants. One of the most famous was Ilario, an Italian painter and architect who lived from around 1470 to 1548. He is best known for his work on the Palazzo della Loggia in Brescia, Italy.
Another notable Ilario was Ilario Altobelli, an Italian cardinal who lived from 1655 to 1752. He served as the Bishop of Rieti and later as the Cardinal-Priest of San Giovanni a Porta Latina.
In the 19th century, there was an Italian composer and conductor named Ilario Cametti, who lived from 1809 to 1878 and composed several operas and other works.
More recently, Ilario Bandini was an Italian footballer who played as a midfielder and was born in 1948. He played for several Italian clubs including Fiorentina and Napoli.
Another notable individual named Ilario was Ilario Fiore, an Italian-American mobster who was a member of the Genovese crime family in New York City during the 20th century.

FAQ
Ilario: questions and answers
How many people in the U.S. are named Ilario?
Name Census puts the figure at roughly 170 living Americans. We arrive at this by taking every SSA birth registration for Ilario 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 2,016,202 US residents.
Is Ilario a common name?
We classify Ilario as "Very Rare". It ranks above 72% of all first names in the SSA dataset by living bearers. Across the full history of the data, 184 babies have been registered with this name.
When was Ilario most popular?
The single biggest year for Ilario was 2006, when 12 babies received the name. The fact that the average living Ilario 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 Ilario in the 2020 Census?
The published 2020 Census first-name tables recorded 491 people with the name Ilario, or 0.16 per 100,000 residents. That placed it at #20,884 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 Ilario 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 Ilario?
In the 2020 Census sex table, Ilario appears almost entirely male. Of the 487 people counted with this name, 99.8% 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 Ilario?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Ilario is Hispanic at 73.3%. The next largest groups are White (22.0%) and American Indian/Alaska Native (1.8%). 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 Ilario most often in the Census?
Hispanic is the largest reported group for people named Ilario in the 2020 Census, accounting for 73.3% (360 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 Ilario in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Ilario a male name?
Yes, 100.0% of people registered as Ilario 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 Ilario still being used today?
Yes. The SSA still recorded Ilario 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 Ilario 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.
