Census
Olegario in the 2020 Census
The 2020 Census recorded 1,584 people with the first name Olegario, which placed it at #8,972 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.

Ancestry and ethnicity for Olegario
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Olegario is Hispanic at 96.8%. The next largest groups are White (1.6%) and Asian/Pacific Islander (1.6%). 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 Olegario 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 Olegario at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Olegario
The name Olegario is derived from the Spanish name Oleguer, which itself comes from the ancient Catalan version of the Germanic name Olegar. This name is thought to have originated in the Visigothic Kingdom, which ruled parts of the Iberian Peninsula from the 5th to 8th centuries CE. The name is composed of two elements: the Germanic root "olah" meaning "heritage" or "inheritance," and the suffix "-gar" meaning "spear."
Olegario became a popular name in medieval Spain, particularly in the region of Catalonia. One of the earliest known bearers of the name was Saint Olegarius, who lived from 1060 to 1137 CE. He served as the Bishop of Barcelona and is venerated as a saint in the Catholic Church.
In the 12th century, the name Olegario appeared in several important historical documents, including the Codex Calixtinus, a medieval book that served as a guide for pilgrims traveling the Camino de Santiago. The name was also mentioned in various chronicles and records of the time, indicating its widespread use among the nobility and clergy in the region.
Over the centuries, several notable figures have borne the name Olegario. One such individual was Olegario de Solís y Carvajal, a Spanish conquistador who participated in the conquest of Mexico in the early 16th century. Another was Olegario Victor Andrade, an Argentine writer and politician born in 1839, who served as a governor and diplomat.
In the 19th century, Olegario Molina Gutiérrez, a Chilean politician and lawyer, was an influential figure in the country's politics. He served as the Minister of Finance and Foreign Affairs during the 1860s. Additionally, Olegario Víctor Andrade, an Argentine writer and politician born in 1839, played a significant role in the literary and political circles of his time.
One of the most renowned bearers of the name was Olegario Víctor Andrade, a celebrated Argentine poet, essayist, and politician who lived from 1839 to 1882. His works, including the poem "Prometeo," contributed significantly to the literary landscape of his era.
While the name Olegario has historical roots and has been borne by notable figures throughout the centuries, it has remained relatively uncommon in modern times, particularly outside of Spanish-speaking regions. However, it continues to serve as a testament to the rich cultural heritage of the Iberian Peninsula and the enduring influence of ancient Germanic and Catalan traditions.

FAQ
Olegario: questions and answers
How many people in the U.S. are named Olegario?
Name Census puts the figure at roughly 334 living Americans. We arrive at this by taking every SSA birth registration for Olegario 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 1,026,211 US residents.
Is Olegario a common name?
We classify Olegario as "Very Rare". It ranks above 80.4% of all first names in the SSA dataset by living bearers. Across the full history of the data, 408 babies have been registered with this name.
When was Olegario most popular?
The single biggest year for Olegario was 1981, when 13 babies received the name. The fact that the average living Olegario is about 37 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
How common was Olegario in the 2020 Census?
The published 2020 Census first-name tables recorded 1,584 people with the name Olegario, or 0.52 per 100,000 residents. That placed it at #8,972 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 Olegario 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 Olegario?
In the 2020 Census sex table, Olegario appears almost entirely male. Of the 1,585 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 Olegario?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Olegario is Hispanic at 96.8%. The next largest groups are White (1.6%) and Asian/Pacific Islander (1.6%). 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 Olegario most often in the Census?
Hispanic is the largest reported group for people named Olegario in the 2020 Census, accounting for 96.8% (1,533 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 Olegario in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Olegario a male name?
Yes, 100.0% of people registered as Olegario 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 Olegario still being used today?
Yes. The SSA still recorded Olegario 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 Olegario 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.
