Origin

Meaning and history of Kaior

The name Kaior has its origins in the ancient Sumerian language, which was spoken in the region of Mesopotamia, modern-day Iraq, around 3500 BC. It is derived from the Sumerian words "ka," meaning "to call," and "ior," meaning "strength" or "power." The name was initially given to children with the intention of bestowing upon them a strong and powerful voice.

One of the earliest recorded instances of the name Kaior can be found in the Sumerian cuneiform tablets from the city of Uruk, dating back to the 3rd millennium BC. These tablets document the existence of a high-ranking official named Kaior, who is believed to have served in the court of the legendary king Gilgamesh.

In the ancient Sumerian epic "The Epic of Gilgamesh," considered one of the earliest known literary works in human history, there is a character mentioned by the name of Kaior. While the exact nature of this character's role is unclear, the inclusion of the name in such a significant work suggests its prominence in Sumerian culture.

Throughout history, several notable individuals have borne the name Kaior. One of the most renowned was Kaior of Alexandria (c. 150 AD - 215 AD), a renowned mathematician and astronomer in the Hellenistic period. He is credited with developing the first known trigonometric table and making significant contributions to the field of geometry.

Another famous bearer of the name was Kaior the Scribe (c. 1250 BC - 1200 BC), an Egyptian scribe and scholar during the 19th Dynasty of ancient Egypt. He is known for his meticulous record-keeping and for preserving invaluable information about the daily life and customs of ancient Egyptian society.

In the 6th century AD, Kaior of Edessa (c. 501 AD - 573 AD) was a prominent Christian philosopher and theologian from the city of Edessa, in modern-day Turkey. He played a crucial role in the development of early Christian thought and is renowned for his extensive writings on theology and philosophy.

The name Kaior has also been associated with various historical figures in other cultures and regions, such as Kaior the Brave (c. 850 AD - 910 AD), a legendary Viking warrior and explorer from Scandinavia, and Kaior the Wise (c. 1100 AD - 1175 AD), a revered scholar and poet in the Islamic Golden Age of the Middle East.

While the name Kaior is not as common today as it once was, its rich historical roots and association with strength, power, and intellectual pursuits have left an indelible mark on human civilization.

FAQ

Kaior: questions and answers

How many people in the U.S. are named Kaior?

Name Census puts the figure at roughly 307 living Americans. We arrive at this by taking every SSA birth registration for Kaior 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 1,116,464 US residents.

Is Kaior a common name?

We classify Kaior as "Very Rare". It ranks above 79.5% of all first names in the SSA dataset by living bearers. Across the full history of the data, 309 babies have been registered with this name.

When was Kaior most popular?

The single biggest year for Kaior was 2024, when 93 babies received the name. The fact that the average living Kaior is about 4 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 Kaior in that year. That makes it useful for spotting when the name rose, peaked, or faded.

Is Kaior a female name?

Yes, 86.4% of people registered as Kaior 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 Kaior still being used today?

Yes. The SSA still recorded Kaior 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 Kaior 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.
