Deciderio in the 2020 Census
The 2020 Census recorded 171 people with the first name Deciderio, which placed it at #42,203 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 Deciderio
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Deciderio is Hispanic at 98.2%. The next largest groups are Asian/Pacific Islander (1.8%). 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 Deciderio 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 Deciderio at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Deciderio
The given name Deciderio has its origins in the Latin language. It is believed to have derived from the Latin word "decidere," which means "to fall off" or "to decide." The name likely emerged during the ancient Roman era, possibly as early as the 1st century AD, when Latin was the predominant language spoken in the Roman Empire.
One of the earliest recorded instances of the name Deciderio can be found in the writings of the Roman scholar and philosopher Seneca the Younger, who lived from around 4 BC to 65 AD. In his work "De Beneficiis" (On Benefits), Seneca mentions a man named Deciderio, though little is known about this individual's life or background.
As Christianity spread throughout the Roman Empire, the name Deciderio may have been adopted by early Christian communities, possibly as a way to emphasize the importance of making decisions and choices in one's faith. However, there is no definitive evidence of the name's usage in religious texts or scriptures from this period.
The first recorded person of historical significance to bear the name Deciderio was Deciderio Longo, an Italian mathematician and astronomer who lived from 1325 to 1389. Longo made significant contributions to the study of celestial mechanics and was instrumental in the development of the Alfonsine Tables, a set of astronomical tables used for calculating the positions of the Sun, Moon, and planets.
Another notable individual named Deciderio was Deciderio Arrighi, an Italian calligrapher and type designer who lived from 1504 to 1576. Arrighi is credited with creating the influential chancery cursive script, which became widely used in Renaissance-era Italy and influenced the development of many modern handwriting styles.
In the 17th century, Deciderio Crescenzi, an Italian botanist and agronomist, made significant contributions to the study of horticulture and agriculture. Born in 1590, Crescenzi authored several influential works, including "Nautica Mediterranea" and "Trattato dell'Agricoltura," which provided detailed instructions on crop cultivation and gardening techniques.
The name Deciderio also appears in the artistic world, with Deciderio Stanzani, an Italian painter active in the late 17th and early 18th centuries. Stanzani was known for his religious paintings and frescoes, many of which adorned churches and buildings throughout his native Bologna and the surrounding regions.
Deciderio Munoz Ramirez, a Spanish-born Jesuit missionary and explorer, was another notable figure who lived from 1651 to 1709. Ramirez traveled extensively throughout the Americas, documenting his experiences and encounters with indigenous cultures in various writings and journals.

FAQ
Deciderio: questions and answers
How many people in the U.S. are named Deciderio?
Name Census puts the figure at roughly 1 living Americans. We arrive at this by taking every SSA birth registration for Deciderio 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 342,754,338 US residents.
Is Deciderio a common name?
We classify Deciderio as "Very Rare". It ranks above 3.8% of all first names in the SSA dataset by living bearers. Across the full history of the data, 10 babies have been registered with this name.
When was Deciderio most popular?
The single biggest year for Deciderio was 1919, when 5 babies received the name. The fact that the average living Deciderio 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 Deciderio in the 2020 Census?
The published 2020 Census first-name tables recorded 171 people with the name Deciderio, or 0.06 per 100,000 residents. That placed it at #42,203 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 Deciderio 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 Deciderio?
In the 2020 Census sex table, Deciderio appears almost entirely male. Of the 176 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 Deciderio?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Deciderio is Hispanic at 98.2%. The next largest groups are Asian/Pacific Islander (1.8%). 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 Deciderio most often in the Census?
Hispanic is the largest reported group for people named Deciderio in the 2020 Census, accounting for 98.2% (168 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 Deciderio in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Deciderio a male name?
Yes, 100.0% of people registered as Deciderio 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 Deciderio still being used today?
Yes. The SSA still recorded Deciderio 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 Deciderio 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.
