Census
Nicasio in the 2020 Census
The 2020 Census recorded 951 people with the first name Nicasio, which placed it at #12,880 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 Nicasio
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Nicasio is Hispanic at 71.2%. The next largest groups are Asian/Pacific Islander (19.2%) and White (6.0%). 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 Nicasio 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 Nicasio at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Nicasio
The name Nicasio has its origins in Latin and Greek, deriving from the Greek word "nikē" meaning "victory" and the Latin name "Nicasius." It was a popular name among early Christians and gained prominence in the 5th century.
The name is believed to have been first used in reference to Saint Nicasius, the 5th Bishop of Rheims in modern-day France. He lived from around 450 AD to 511 AD and was martyred during the barbarian invasions of Gaul. His feast day is celebrated on December 14th in the Roman Catholic Church.
One of the earliest recorded uses of the name can be found in the writings of the 6th-century scholar Venantius Fortunatus, who wrote a hymn in honor of Saint Nicasius. The name also appears in various medieval texts and chronicles, particularly those related to the history of the region around Rheims.
Some notable historical figures who bore the name Nicasio include:
1. Nicasio de Jesús María (1693-1784), a Spanish Catholic priest and missionary who worked in the Philippines and is recognized as a martyr by the Catholic Church.
2. Nicasio Gallego (1777-1853), a Spanish Neoclassical poet and playwright who served as the director of the Royal Spanish Academy.
3. Nicasio Ríos (1807-1880), a Mexican politician and military officer who served as the Governor of Jalisco and fought in various wars and conflicts.
4. Nicasio Zamora (1820-1887), a Mexican general and politician who served as the Governor of Nuevo León and played a significant role in the Reform War and the French Intervention in Mexico.
5. Nicasio Álvarez de Cienfuegos (1764-1809), a Spanish writer, poet, and dramatist who was known for his satirical works and contributions to the Spanish Enlightenment.
The name Nicasio continues to be used, particularly in Spanish-speaking countries, where it has maintained its connection to its religious and historical roots.

FAQ
Nicasio: questions and answers
How many people in the U.S. are named Nicasio?
Name Census puts the figure at roughly 274 living Americans. We arrive at this by taking every SSA birth registration for Nicasio 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 1,250,928 US residents.
Is Nicasio a common name?
We classify Nicasio as "Very Rare". It ranks above 78.2% of all first names in the SSA dataset by living bearers. Across the full history of the data, 289 babies have been registered with this name.
When was Nicasio most popular?
The single biggest year for Nicasio was 1998, when 13 babies received the name. The fact that the average living Nicasio is about 29 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
How common was Nicasio in the 2020 Census?
The published 2020 Census first-name tables recorded 951 people with the name Nicasio, or 0.31 per 100,000 residents. That placed it at #12,880 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 Nicasio 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 Nicasio?
In the 2020 Census sex table, Nicasio appears almost entirely male. Of the 947 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 Nicasio?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Nicasio is Hispanic at 71.2%. The next largest groups are Asian/Pacific Islander (19.2%) and White (6.0%). 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 Nicasio most often in the Census?
Hispanic is the largest reported group for people named Nicasio in the 2020 Census, accounting for 71.2% (677 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 Nicasio in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Nicasio a male name?
Yes, 100.0% of people registered as Nicasio 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 Nicasio still being used today?
Yes. The SSA still recorded Nicasio 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 Nicasio 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.
