Origin
Meaning and history of Trillion
The given name Trillion is a modern invention that does not have any known historical roots or origins in any language or culture. It is a recently coined name inspired by the numerical term "trillion," which refers to the number 1,000,000,000,000 or 10^12.
Trillion is an extremely rare name, and there are no known historical records or ancient texts that mention individuals with this name. It is unlikely to have been used as a name until the 20th or 21st century, as the concept of large numerical values like trillions only became relevant with modern mathematics and scientific advancements.
Given its unique and unconventional nature, there are very few recorded instances of individuals being named Trillion. One of the earliest known examples is Trillion Watts, a fictional character from the 1988 science fiction novel "Earth" by David Brin. Trillion Watts was an artificial intelligence construct in the novel.
Another example is Trillion Claverie, a French mathematician and computer scientist born in 1967. Claverie is known for her work in computational geometry and has published several research papers in this field.
In 2014, a baby girl named Trillion Atlas was born in South Africa, making headlines for her unusual name. Her parents reportedly chose the name because they wanted something unique and meaningful.
Trillion Reid, an American writer and educator, is another individual with this first name. She has authored several books on topics related to personal growth and self-improvement.
While these are a few documented examples of individuals named Trillion, it remains an exceptionally rare and unconventional name choice. As a modern invention without any historical or cultural roots, it is unlikely to have been used consistently throughout history.

FAQ
Trillion: questions and answers
How many people in the U.S. are named Trillion?
Name Census puts the figure at roughly 142 living Americans. We arrive at this by taking every SSA birth registration for Trillion 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 2,413,763 US residents.
Is Trillion a common name?
We classify Trillion as "Very Rare". It ranks above 69.5% of all first names in the SSA dataset by living bearers. Across the full history of the data, 143 babies have been registered with this name.
When was Trillion most popular?
The single biggest year for Trillion was 2022, when 18 babies received the name. The fact that the average living Trillion is about 9 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
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 Trillion in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Trillion a male name?
Yes, 100.0% of people registered as Trillion 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 Trillion still being used today?
Yes. The SSA still recorded Trillion 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 Trillion 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.
Does every first name have Census demographic data?
No. The public Census first-name release only covers names that met the Bureau's publication rules, so many rarer names in the SSA files do not have a published Census demographic snapshot. In those cases, the page still shows the SSA trend, gender history, and state data.
