Roizy in the 2020 Census
The 2020 Census recorded 285 people with the first name Roizy, which placed it at #30,528 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 Roizy
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Roizy is White at 95.1%. The next largest groups are Hispanic (3.2%) and Two or More Races (1.1%). 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 Roizy 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 Roizy at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Roizy
The name Roizy is believed to have its origins in the ancient Gaulish language, spoken by the Celtic tribes that inhabited modern-day France and parts of western Europe during the Iron Age. It is thought to be derived from the Proto-Celtic root *rog-, meaning "to see" or "to perceive," with the diminutive suffix -izy added, possibly indicating a connection to a profession or role related to observation or perception.
One of the earliest recorded instances of the name Roizy can be found in the Gallo-Roman inscriptions of the 3rd century CE, where it appears as "Rogitius," likely a Latinized form of the original Gaulish name. This lends credence to the theory of its Celtic origins and suggests that the name was in use among the Gaulish population during the Roman period.
In the Middle Ages, the name Roizy seems to have been particularly popular in the regions of Normandy and Brittany, where it appears in various forms, such as "Roizy," "Roisy," and "Roissy." This could be attributed to the strong Celtic cultural influence in these areas, which may have preserved the name's linguistic roots.
One notable figure in history who bore the name Roizy was Roizy de Warwick, a 12th-century Norman nobleman and knight who participated in the Third Crusade alongside Richard the Lionheart. Another was Roizy de Montfort, a 13th-century French noblewoman and patron of the arts, known for her patronage of the troubadour tradition.
In the 15th century, a Roizy de Chambord, a French courtier and advisor to King Louis XI, gained prominence for his diplomatic skills and role in negotiating treaties with neighboring kingdoms. A century later, Roizy de Sancerre, a renowned military commander, distinguished himself in the French Wars of Religion, defending the city of Sancerre during its prolonged siege.
One of the most famous bearers of the name Roizy was Roizy de La Fontaine, a 17th-century French fabulist and poet whose collection of fables, known as the Fables of La Fontaine, is considered a masterpiece of French literature and has been translated into numerous languages.
While the name Roizy has waned in popularity in modern times, its rich history and linguistic roots offer a fascinating glimpse into the cultural tapestry of ancient Gaul and the enduring influence of Celtic traditions on European naming practices.

FAQ
Roizy: questions and answers
How many people in the U.S. are named Roizy?
Name Census puts the figure at roughly 387 living Americans. We arrive at this by taking every SSA birth registration for Roizy 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 885,670 US residents.
Is Roizy a common name?
We classify Roizy as "Very Rare". It ranks above 82% of all first names in the SSA dataset by living bearers. Across the full history of the data, 392 babies have been registered with this name.
When was Roizy most popular?
The single biggest year for Roizy was 2014, when 22 babies received the name. The fact that the average living Roizy is about 15 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
How common was Roizy in the 2020 Census?
The published 2020 Census first-name tables recorded 285 people with the name Roizy, or 0.09 per 100,000 residents. That placed it at #30,528 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 Roizy 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 Roizy?
In the 2020 Census sex table, Roizy appears almost entirely female. Of the 280 people counted with this name, 99.3% were female and only a very small share were male. 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 Roizy?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Roizy is White at 95.1%. The next largest groups are Hispanic (3.2%) and Two or More Races (1.1%). 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 Roizy most often in the Census?
White is the largest reported group for people named Roizy in the 2020 Census, accounting for 95.1% (271 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 Roizy in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Roizy a female name?
Yes, 100.0% of people registered as Roizy in the SSA data are female. 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 Roizy still being used today?
Yes. The SSA still recorded Roizy 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 Roizy 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.
