Eon in the 2020 Census
The 2020 Census recorded 555 people with the first name Eon, which placed it at #19,209 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 Eon
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Eon is Black at 45.4%. The next largest groups are White (25.2%) and Asian/Pacific Islander (15.1%). 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 Eon 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 Eon at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Eon
The name Eon has its origins in Greek, derived from the word "aion," which means "age" or "eternity." This name has been associated with concepts of time, duration, and the infinite expanse of the universe.
In Greek mythology, Aion was a personification of eternity and the perpetual flow of time. The name Eon was often used to represent this concept, reflecting the never-ending cycle of existence and the eternal nature of the cosmos.
One of the earliest recorded instances of the name Eon can be found in the writings of the ancient Greek philosopher Plato. In his work "Timaeus," Plato discussed the concept of "aion" as a representation of the eternal and unchanging nature of the universe.
Throughout history, the name Eon has been used sparingly, but it has been associated with individuals who have made significant contributions to various fields of study or have had a lasting impact on society.
One notable figure named Eon was a 12th-century French religious leader and mystic, also known as Eon de l'Etoile. He claimed to be the embodiment of the Son of God and gained a considerable following before being condemned as a heretic by the Catholic Church.
Another individual with the name Eon was Eon Mokushiki (1915-1995), a Japanese artist and sculptor known for his abstract works and his exploration of form and space. His sculptures are part of several renowned collections around the world.
In the field of science, Eon de Beaumont (1728-1786) was a French naturalist and geologist who made significant contributions to the understanding of the Earth's geological history and the classification of rock formations.
Eon Khanhkru (1912-1992) was a prominent Thai diplomat and statesman who served as the Ambassador of Thailand to several countries, including the United States and the United Kingdom.
Eon Higgins (1920-2008) was an American writer and historian who authored several books on the history of the American West and the experiences of Native American tribes.
While the name Eon has been used throughout history, it has remained relatively uncommon, perhaps due to its philosophical and abstract connotations. However, those who have borne this name have often been associated with ideas of eternity, the pursuit of knowledge, and a desire to understand the fundamental nature of existence.

FAQ
Eon: questions and answers
How many people in the U.S. are named Eon?
Name Census puts the figure at roughly 394 living Americans. We arrive at this by taking every SSA birth registration for Eon 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 869,935 US residents.
Is Eon a common name?
We classify Eon as "Very Rare". It ranks above 82.2% of all first names in the SSA dataset by living bearers. Across the full history of the data, 404 babies have been registered with this name.
When was Eon most popular?
The single biggest year for Eon was 2024, when 21 babies received the name. The fact that the average living Eon 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 Eon in the 2020 Census?
The published 2020 Census first-name tables recorded 555 people with the name Eon, or 0.18 per 100,000 residents. That placed it at #19,209 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 Eon 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 Eon?
In the 2020 Census sex table, Eon leans strongly male. 506 people counted with this name were male (91.8%), compared with 45 female bearers (8.2%). 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 Eon?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Eon is Black at 45.4%. The next largest groups are White (25.2%) and Asian/Pacific Islander (15.1%). 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 Eon most often in the Census?
Black is the largest reported group for people named Eon in the 2020 Census, accounting for 45.4% (252 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 Eon in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Eon a male name?
Yes, 100.0% of people registered as Eon 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 Eon still being used today?
Yes. The SSA still recorded Eon 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 Eon 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. You can read the full calculation on our methodology page.
