Eustacia in the 2020 Census
The 2020 Census recorded 419 people with the first name Eustacia, which placed it at #23,378 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 Eustacia
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Eustacia is Hispanic at 47.3%. The next largest groups are Black (23.9%) and White (22.2%). 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 Eustacia 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 Eustacia at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Eustacia
The name Eustacia has its origins in ancient Greek, derived from the word "eustathes" which means "constant" or "steadfast." It was a name favored by Greek families, particularly in the classical period between the 5th and 4th centuries BCE.
One of the earliest recorded uses of the name Eustacia can be found in the works of the ancient Greek historian Xenophon, who mentioned a woman named Eustacia in his writings. The name also appears in various Greek inscriptions and records from that era.
In the early Christian period, Eustacia became a popular name among the Greek-speaking populations of the Byzantine Empire. It was sometimes associated with the martyr Saint Eustathius, who lived in the 2nd century CE. The name spread to other regions of the Mediterranean and Europe through the influence of the Byzantine Church.
During the Middle Ages, the name Eustacia was relatively uncommon but still in use in various parts of Europe. One notable figure was Eustacia of Aragon (1180-1222), a Catalan noblewoman who was the wife of King Peter II of Aragon.
In the Renaissance period, the name experienced a resurgence in popularity, particularly in Italy and France. One famous bearer of the name was Eustacia Calafato (1491-1552), an Italian Renaissance poet and scholar from Genoa.
The name Eustacia also found its way into English literature, most notably in the novel "The Return of the Native" by Thomas Hardy, published in 1878. The novel's protagonist, Eustacia Vye, was a complex and passionate character whose name reflected her strong-willed nature.
Other notable individuals named Eustacia throughout history include Eustacia Akerberg (1837-1887), a Swedish educator and women's rights advocate, and Eustacia Panker (1890-1967), an American civil rights activist and social worker from Louisiana.

FAQ
Eustacia: questions and answers
How many people in the U.S. are named Eustacia?
Name Census puts the figure at roughly 138 living Americans. We arrive at this by taking every SSA birth registration for Eustacia 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 2,483,727 US residents.
Is Eustacia a common name?
We classify Eustacia as "Very Rare". It ranks above 69.1% of all first names in the SSA dataset by living bearers. Across the full history of the data, 156 babies have been registered with this name.
When was Eustacia most popular?
The single biggest year for Eustacia was 1971, when 15 babies received the name. The fact that the average living Eustacia is about 47 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
How common was Eustacia in the 2020 Census?
The published 2020 Census first-name tables recorded 419 people with the name Eustacia, or 0.14 per 100,000 residents. That placed it at #23,378 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 Eustacia 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 Eustacia?
In the 2020 Census sex table, Eustacia appears almost entirely female. Of the 415 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 Eustacia?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Eustacia is Hispanic at 47.3%. The next largest groups are Black (23.9%) and White (22.2%). 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 Eustacia most often in the Census?
Hispanic is the largest reported group for people named Eustacia in the 2020 Census, accounting for 47.3% (198 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 Eustacia in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Eustacia a female name?
Yes, 100.0% of people registered as Eustacia 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 Eustacia still being used today?
Yes. The SSA still recorded Eustacia 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 Eustacia 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.
