Origin
Meaning and history of Casio
The given name Casio has its roots in the Latin language. It is believed to have originated from the word "casia," which means "cinnamon tree." The name is thought to have first emerged during the Roman period, around the early centuries AD.
In ancient Rome, the cinnamon tree was highly valued for its aromatic bark, which was used in various rituals, perfumes, and medicinal preparations. It is possible that the name Casio was initially given to individuals involved in the cultivation, trade, or use of this precious spice.
One of the earliest recorded instances of the name Casio can be found in the writings of Pliny the Elder, a Roman author and naturalist from the 1st century AD. He mentioned a Roman soldier named Casio Longinus who served in the Roman legions during the conquest of Britain.
In the 4th century AD, there was a notable figure named Casio Longino, who was a Roman philosopher and grammarian. He is known for his commentaries on various classical works and his contributions to the study of language and literature.
During the Middle Ages, the name Casio appeared sporadically in various regions of Europe. One notable bearer of the name was Casio da Narni, an Italian friar and religious writer who lived in the 13th century. He authored several works on spiritual topics and was renowned for his piety.
In the Renaissance period, Casio Famiano was an Italian humanist and scholar from the 15th century. He was widely respected for his knowledge of classical literature and his translations of ancient Greek texts.
Another prominent figure with the name Casio was Casio Parmense, an Italian painter and architect who lived in the 16th century. He was involved in the design and construction of several notable buildings in Parma and other cities in northern Italy.

FAQ
Casio: questions and answers
How many people in the U.S. are named Casio?
Name Census puts the figure at roughly 6 living Americans. We arrive at this by taking every SSA birth registration for Casio 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 57,125,723 US residents.
Is Casio a common name?
We classify Casio as "Very Rare". It ranks above 22.3% of all first names in the SSA dataset by living bearers. Across the full history of the data, 6 babies have been registered with this name.
When was Casio most popular?
The single biggest year for Casio was 2023, when 6 babies received the name. The fact that the average living Casio is about 3 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 Casio in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Casio a male name?
Yes, 100.0% of people registered as Casio 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 Casio still being used today?
Yes. The SSA still recorded Casio 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 Casio 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.
