Lionso in the 2020 Census
The 2020 Census recorded 98 people with the first name Lionso, which placed it at #53,484 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 Lionso
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Lionso is Hispanic at 99.0%. The next largest groups are White (1.0%). 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 Lionso 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 Lionso at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Lionso
The name Lionso has its roots in ancient Iberian culture, originating from the Basque region of present-day Spain and France. Linguists trace its etymology back to the Proto-Basque word "leintsoa," which translates to "faithful" or "loyal." The earliest recorded instances of the name date back to the 8th century CE, where it appears in medieval Basque manuscripts and records.
During the Middle Ages, Lionso emerged as a popular moniker among the Basque nobility and was often associated with individuals renowned for their unwavering loyalty and honor. One notable bearer of the name was Lionso de Azpeitia, a 12th-century Basque knight who served under King Alfonso VIII of Castile. His bravery and allegiance to the crown were celebrated in various epic poems and ballads of the era.
In the 14th century, the name gained further prominence with the rise of Lionso de Sasiola, a revered Basque scholar and philosopher. His influential treatises on ethics and morality, which emphasized the virtues of fidelity and integrity, likely contributed to the name's enduring positive connotations.
As the centuries progressed, the name Lionso transcended its Basque roots and found its way into other European cultures. In 16th-century Italy, Lionso Lippi, a renowned Renaissance painter hailing from Florence, left an indelible mark on the art world with his masterful frescoes adorning various churches and palaces.
The 18th century saw the birth of Lionso de Aragon, a Spanish naval commander whose exploits during the War of the Spanish Succession earned him a place in the annals of maritime history. His unwavering loyalty to the Spanish crown and his daring exploits at sea cemented his reputation as a formidable leader.
In more recent times, the name Lionso gained recognition through the achievements of Lionso Martínez, a 19th-century Mexican poet and activist. His impassioned works championed the causes of social justice and indigenous rights, resonating with readers across Latin America and beyond.

FAQ
Lionso: questions and answers
How many people in the U.S. are named Lionso?
Name Census puts the figure at roughly 11 living Americans. We arrive at this by taking every SSA birth registration for Lionso 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 31,159,485 US residents.
Is Lionso a common name?
We classify Lionso as "Very Rare". It ranks above 30.8% of all first names in the SSA dataset by living bearers. Across the full history of the data, 11 babies have been registered with this name.
When was Lionso most popular?
The single biggest year for Lionso was 2000, when 6 babies received the name. The fact that the average living Lionso is about 25 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
How common was Lionso in the 2020 Census?
The published 2020 Census first-name tables recorded 98 people with the name Lionso, or 0.03 per 100,000 residents. That placed it at #53,484 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 Lionso 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 Lionso?
In the 2020 Census sex table, Lionso appears almost entirely male. Of the 107 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 Lionso?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Lionso is Hispanic at 99.0%. The next largest groups are White (1.0%). 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 Lionso most often in the Census?
Hispanic is the largest reported group for people named Lionso in the 2020 Census, accounting for 99.0% (97 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 Lionso in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Lionso a male name?
Yes, 100.0% of people registered as Lionso 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 Lionso still being used today?
Yes. The SSA still recorded Lionso 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 Lionso 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.
