Census
Seferino in the 2020 Census
The 2020 Census recorded 1,199 people with the first name Seferino, which placed it at #10,911 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.

In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Seferino is Hispanic at 96.2%. The next largest groups are White (2.0%) and American Indian/Alaska Native (0.9%). 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 Seferino 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 Seferino at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Seferino
The name Seferino is of Spanish origin, derived from the Latin name Severinus, which itself comes from the Roman family name Severus, meaning "severe" or "strict." It is believed to have emerged during the late Roman period, around the 3rd or 4th century AD.
In its early days, the name Severinus was associated with Christian saints and martyrs, such as Saint Severinus of Noricum, a 5th-century Roman Catholic saint and apostle of Noricum, a region that now encompasses parts of Austria and Bavaria. The name gained popularity in Christian communities across Europe during the Middle Ages.
One of the earliest recorded instances of the name Seferino can be found in the 12th century, when Seferino de Guzman, a Spanish nobleman and military leader, was mentioned in historical records. He played a significant role in the Reconquista, the centuries-long struggle to drive the Moors out of the Iberian Peninsula.
Another notable figure with the name Seferino was Seferino Sánchez, a 19th-century Mexican general who fought in the Mexican-American War (1846-1848) and the Reform War (1857-1861). He was born in 1805 and died in 1871.
In the arts, Seferino Nández was a renowned Uruguayan painter and sculptor active in the late 19th and early 20th centuries. He is best known for his works depicting rural life and landscapes in Uruguay. Nández was born in 1868 and died in 1930.
Seferino Blanco was a Spanish writer and journalist from the early 20th century. He was a prominent figure in the literary circles of Madrid and contributed to several newspapers and magazines. Blanco was born in 1879 and died in 1938.
Finally, Seferino Neri was an Italian architect and urban planner who lived in the 18th century. He is credited with designing several notable buildings and urban spaces in Rome, including the Piazza del Popolo and the Pincian Hill gardens. Neri was born in 1685 and died in 1767.

FAQ
Seferino: questions and answers
How many people in the U.S. are named Seferino?
Name Census puts the figure at roughly 741 living Americans. We arrive at this by taking every SSA birth registration for Seferino 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 462,556 US residents.
Is Seferino a common name?
We classify Seferino as "Very Rare". It ranks above 88% of all first names in the SSA dataset by living bearers. Across the full history of the data, 1,235 babies have been registered with this name.
When was Seferino most popular?
The single biggest year for Seferino was 1952, when 23 babies received the name. The fact that the average living Seferino is about 52 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
How common was Seferino in the 2020 Census?
The published 2020 Census first-name tables recorded 1,199 people with the name Seferino, or 0.40 per 100,000 residents. That placed it at #10,911 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 Seferino 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 Seferino?
In the 2020 Census sex table, Seferino appears almost entirely male. Of the 1,201 people counted with this name, 99.4% 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 Seferino?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Seferino is Hispanic at 96.2%. The next largest groups are White (2.0%) and American Indian/Alaska Native (0.9%). 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 Seferino most often in the Census?
Hispanic is the largest reported group for people named Seferino in the 2020 Census, accounting for 96.2% (1,154 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 Seferino in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Seferino a male name?
Yes, 100.0% of people registered as Seferino 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 Seferino still being used today?
Yes. The SSA still recorded Seferino 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 Seferino 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.
