Jilberto in the 2020 Census
The 2020 Census recorded 371 people with the first name Jilberto, which placed it at #25,534 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 Jilberto
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Jilberto is Hispanic at 98.9%. The next largest groups are White (0.5%) and Asian/Pacific Islander (0.5%). 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 Jilberto 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 Jilberto at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Jilberto
The given name Jilberto has its origins in the medieval Spanish language, emerging around the 11th century CE. It is believed to be a portmanteau formed by combining the Germanic name Gil, derived from the root "gild" meaning "value" or "reward," with the Latin name Hubertus, meaning "bright mind" or "brilliant spirit." This unique blend of Germanic and Latin elements suggests a cultural exchange during the Reconquista period in the Iberian Peninsula.
The earliest recorded use of the name Jilberto can be traced back to a 12th-century document from the Kingdom of Aragon, where it was mentioned as the name of a local nobleman. During the subsequent centuries, the name gained popularity among the Spanish nobility and nobility-adjacent classes, particularly in the regions of Castile and Andalusia.
One of the earliest notable figures bearing the name Jilberto was a 13th-century poet and troubadour from Córdoba, whose works celebrated the themes of courtly love and chivalry. His poetic legacy contributed to the preservation and dissemination of the name throughout the medieval Iberian world.
In the 16th century, a Spanish explorer named Jilberto de Alvarado accompanied Hernán Cortés on his expedition to Mexico, earning a place in the annals of the Spanish conquest of the Americas. His exploits and bravery during the conquest campaigns helped solidify the name's association with adventure and exploration.
During the Golden Age of Spanish literature in the 17th century, a prominent playwright named Jilberto de Vega y Carpio gained international acclaim for his works, which included masterpieces such as "La vida es sueño" and "El burlador de Sevilla." His contributions to the Spanish theater and literature further elevated the prestige of the name Jilberto.
In the 19th century, a Spanish military commander named Jilberto Fernández de Córdoba distinguished himself in the Carlist Wars, earning several honors and titles for his leadership and valor on the battlefield. His exploits cemented the name's association with military prowess and bravery.
While the name Jilberto has seen a decline in popularity in recent times, it remains a part of the rich tapestry of Spanish cultural heritage, evoking images of medieval nobility, literary greatness, and adventurous spirits from the past.

FAQ
Jilberto: questions and answers
How many people in the U.S. are named Jilberto?
Name Census puts the figure at roughly 186 living Americans. We arrive at this by taking every SSA birth registration for Jilberto 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 1,842,765 US residents.
Is Jilberto a common name?
We classify Jilberto as "Very Rare". It ranks above 73.2% of all first names in the SSA dataset by living bearers. Across the full history of the data, 194 babies have been registered with this name.
When was Jilberto most popular?
The single biggest year for Jilberto was 1990, when 11 babies received the name. The fact that the average living Jilberto is about 33 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
How common was Jilberto in the 2020 Census?
The published 2020 Census first-name tables recorded 371 people with the name Jilberto, or 0.12 per 100,000 residents. That placed it at #25,534 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 Jilberto 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 Jilberto?
In the 2020 Census sex table, Jilberto appears almost entirely male. Of the 366 people counted with this name, 100.0% 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 Jilberto?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Jilberto is Hispanic at 98.9%. The next largest groups are White (0.5%) and Asian/Pacific Islander (0.5%). 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 Jilberto most often in the Census?
Hispanic is the largest reported group for people named Jilberto in the 2020 Census, accounting for 98.9% (367 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 Jilberto in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Jilberto a male name?
Yes, 100.0% of people registered as Jilberto 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 Jilberto still being used today?
Yes. The SSA still recorded Jilberto 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 Jilberto 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.
