Census
Eloiza in the 2020 Census
The 2020 Census recorded 273 people with the first name Eloiza, which placed it at #31,391 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.

In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Eloiza is Hispanic at 77.7%. The next largest groups are White (13.6%) and Asian/Pacific Islander (7.7%). 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 Eloiza 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 Eloiza at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Eloiza
The name Eloiza has its origins in the Spanish language and culture. It is a variation of the name Eloísa, which is the Spanish form of the French name Héloïse. The name Héloïse is derived from the Germanic name Hailawiz or Hailawisa, which means "healthy" or "whole."
The name Eloiza gained popularity during the Middle Ages, particularly in the 12th century. It is associated with the tragic love story of Héloïse and Abélard, a famous French scholar and philosopher. Héloïse was a brilliant and educated woman who fell in love with her tutor, Abélard. Their forbidden romance and subsequent separation became a legendary tale of forbidden love and intellectual pursuit.
One of the earliest recorded instances of the name Eloiza can be found in the works of the Spanish poet Juan Ruiz, who lived in the 14th century. In his work "Libro de Buen Amor" (Book of Good Love), he mentioned a character named Eloiza, suggesting that the name was in use during that time period in Spain.
Throughout history, several notable women have borne the name Eloiza. One of the most famous was Eloiza Días de Villegas (1505-1554), a Spanish poet and writer who was renowned for her religious and secular works. Another notable figure was Eloiza Clementina Cuenca Aguilar (1834-1891), a Ecuadorian poet and educator who played a significant role in promoting education and literature in her country.
In the 16th century, Eloiza de Herrera (1536-1588) was a Spanish noblewoman and poet known for her religious poetry and her patronage of the arts and literature. Eloiza de Castro (1567-1637), a Portuguese writer and nun, was also a prominent figure during the Renaissance period and is remembered for her mystical and devotional writings.
Eloiza de Cepeda y Ahumada (1515-1582), better known as St. Teresa of Ávila, was a Spanish mystic, writer, and reformer of the Carmelite Order. She is renowned for her spiritual writings and her significant contributions to the Catholic Church during the Counter-Reformation.
While the name Eloiza has its roots in the Spanish language and culture, it has been adopted and adapted in various other cultures and languages over the centuries, reflecting the diverse and rich history of this beautiful name.

FAQ
Eloiza: questions and answers
How many people in the U.S. are named Eloiza?
Name Census puts the figure at roughly 40 living Americans. We arrive at this by taking every SSA birth registration for Eloiza 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 8,568,858 US residents.
Is Eloiza a common name?
We classify Eloiza as "Very Rare". It ranks above 51% of all first names in the SSA dataset by living bearers. Across the full history of the data, 53 babies have been registered with this name.
When was Eloiza most popular?
The single biggest year for Eloiza was 1921, when 6 babies received the name. The fact that the average living Eloiza is about 23 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
How common was Eloiza in the 2020 Census?
The published 2020 Census first-name tables recorded 273 people with the name Eloiza, or 0.09 per 100,000 residents. That placed it at #31,391 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 Eloiza 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 Eloiza?
In the 2020 Census sex table, Eloiza appears almost entirely female. Of the 267 people counted with this name, 100.0% 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 Eloiza?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Eloiza is Hispanic at 77.7%. The next largest groups are White (13.6%) and Asian/Pacific Islander (7.7%). 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 Eloiza most often in the Census?
Hispanic is the largest reported group for people named Eloiza in the 2020 Census, accounting for 77.7% (212 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 Eloiza in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Eloiza a female name?
Yes, 100.0% of people registered as Eloiza 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 Eloiza still being used today?
Yes. The SSA still recorded Eloiza 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 Eloiza 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.
