Census
Sigfredo in the 2020 Census
The 2020 Census recorded 766 people with the first name Sigfredo, which placed it at #15,123 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 Sigfredo
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Sigfredo is Hispanic at 95.0%. The next largest groups are Asian/Pacific Islander (3.5%) and White (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 Sigfredo 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 Sigfredo at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Sigfredo
The name Sigfredo has its origins in the Germanic languages, derived from the Old Norse name Sigfriðr. This name is a compound of two elements: "sigr" meaning victory and "friðr" meaning peace or protection. Essentially, the name translates to "victorious peace" or "winner of peace."
In its earliest forms, the name appeared as Sigifrith and Siegfried in various Germanic languages and dialects. It gained particular prominence through its use in the Nibelungenlied, the epic poem from medieval German literature. The hero Siegfried plays a central role in this legendary tale, solidifying the name's association with heroic figures and acts of valor.
One of the earliest recorded individuals bearing this name was Sigfredo, Count of Burgos, a nobleman who lived in the 10th century during the reign of the Umayyad Caliphate in present-day Spain. He played a significant role in the Christian resistance against the Moors and is mentioned in several chronicles from that era.
During the Middle Ages, the name Sigfredo gained popularity among the nobility and aristocracy across various European regions. Notable figures include Sigfredo, Count of Anjou (c. 870 - c. 942), a powerful nobleman in what is now western France, and Sigfredo, Duke of Swabia (c. 915 - 971), a prominent figure in the Holy Roman Empire.
In the Renaissance period, the Italian form of the name, Sigifredo, was used by several notable individuals. One example is Sigifredo Gonzaga (1480 - 1525), an Italian nobleman and military leader who played a crucial role in the Italian Wars of the early 16th century.
Another historical figure bearing this name was Sigfredo Bárcena (1892 - 1947), a Mexican poet and writer who was a prominent figure in the Mexican literary renaissance of the early 20th century. His work was celebrated for its lyrical quality and deep insight into the human condition.
Sigfredo Alfaro (1934 - 2020) was a renowned Panamanian artist and painter, recognized for his vibrant and expressive works that captured the essence of his native country's landscapes and cultural traditions. His art is celebrated both nationally and internationally, and he is considered one of the most influential figures in Panamanian art history.

FAQ
Sigfredo: questions and answers
How many people in the U.S. are named Sigfredo?
Name Census puts the figure at roughly 228 living Americans. We arrive at this by taking every SSA birth registration for Sigfredo 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 1,503,309 US residents.
Is Sigfredo a common name?
We classify Sigfredo as "Very Rare". It ranks above 75.9% of all first names in the SSA dataset by living bearers. Across the full history of the data, 252 babies have been registered with this name.
When was Sigfredo most popular?
The single biggest year for Sigfredo was 1958, when 14 babies received the name. The fact that the average living Sigfredo is about 50 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
How common was Sigfredo in the 2020 Census?
The published 2020 Census first-name tables recorded 766 people with the name Sigfredo, or 0.25 per 100,000 residents. That placed it at #15,123 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 Sigfredo 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 Sigfredo?
In the 2020 Census sex table, Sigfredo appears almost entirely male. Of the 759 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 Sigfredo?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Sigfredo is Hispanic at 95.0%. The next largest groups are Asian/Pacific Islander (3.5%) and White (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 Sigfredo most often in the Census?
Hispanic is the largest reported group for people named Sigfredo in the 2020 Census, accounting for 95.0% (728 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 Sigfredo in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Sigfredo a male name?
Yes, 100.0% of people registered as Sigfredo 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 Sigfredo still being used today?
Yes. The SSA still recorded Sigfredo 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 Sigfredo 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.
