Hermione in the 2020 Census
The 2020 Census recorded 1,213 people with the first name Hermione, which placed it at #10,814 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 Hermione
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Hermione is White at 32.5%. The next largest groups are Hispanic (31.2%) and Black (22.8%). 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 Hermione 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 Hermione at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Hermione
Hermione is a given name of Greek origin, derived from the name Hermes, the Greek god associated with fertility, luck, and travel. The name Hermione means "messenger" or "earthly" in Greek.
The first recorded use of the name Hermione dates back to Greek mythology, where it was the name of a daughter of Menelaus and Helen in the Iliad and the Odyssey. In these ancient Greek epics, Hermione was depicted as a beautiful and virtuous young woman who was promised to Neoptolemus, the son of Achilles.
In the 5th century BC, Hermione was a character in the play "Andromache" by the Greek tragedian Euripides, where she was portrayed as a jealous and vengeful wife who sought to kill her husband's concubine and her son.
During the Renaissance period, the name Hermione became popular among the educated classes who were familiar with classical Greek literature. One notable bearer of the name was Hermione, the daughter of Sir William Cavendish and Lady Margaret Cavendish, who lived in the 17th century.
In the 18th century, the name Hermione was used by the English writer and philosopher Mary Wollstonecraft for one of the characters in her novel "Maria, or The Wrongs of Woman."
Another famous Hermione was Hermione Gingold (1897-1987), an English actress and comedienne known for her roles in films such as "Gigi" and "The Music Man."
The name Hermione gained renewed popularity in the late 20th century after its appearance in the Harry Potter book series by J.K. Rowling, where Hermione Granger was one of the main characters and best friends of Harry Potter.

FAQ
Hermione: questions and answers
How many people in the U.S. are named Hermione?
Name Census puts the figure at roughly 1,587 living Americans. We arrive at this by taking every SSA birth registration for Hermione 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 215,976 US residents.
Is Hermione a common name?
We classify Hermione as "Rare". It ranks above 92.7% of all first names in the SSA dataset by living bearers. Across the full history of the data, 1,744 babies have been registered with this name.
When was Hermione most popular?
The single biggest year for Hermione was 2024, when 122 babies received the name. The fact that the average living Hermione is about 12 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
How common was Hermione in the 2020 Census?
The published 2020 Census first-name tables recorded 1,213 people with the name Hermione, or 0.40 per 100,000 residents. That placed it at #10,814 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 Hermione 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 Hermione?
In the 2020 Census sex table, Hermione leans strongly female. 1,206 people counted with this name were female (98.9%), compared with 14 male bearers (1.1%). 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 Hermione?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Hermione is White at 32.5%. The next largest groups are Hispanic (31.2%) and Black (22.8%). 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 Hermione most often in the Census?
White is the largest reported group for people named Hermione in the 2020 Census, accounting for 32.5% (394 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 Hermione in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Hermione a female name?
Yes, 100.0% of people registered as Hermione 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 Hermione still being used today?
Yes. The SSA still recorded Hermione 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 Hermione 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.
