Origin
Meaning and history of Kaiis
The name Kaiis is believed to have originated in ancient Sumerian civilization, which flourished in the region of Mesopotamia (modern-day Iraq) around 3500-3000 BCE. It is derived from the Sumerian word "kai," meaning "earth" or "land," and the suffix "-is," which denotes possession or belonging. Thus, the name Kaiis could be interpreted as "belonging to the earth" or "of the land."
In Sumerian mythology, the goddess Inanna, also known as Ishtar, was associated with the earth and fertility. It's possible that the name Kaiis was initially given to individuals born during planting or harvesting seasons, as a way to honor the goddess and ensure a bountiful yield.
The earliest known record of the name Kaiis can be found in ancient Sumerian cuneiform tablets dating back to around 2500 BCE. These tablets were discovered in the archaeological sites of Uruk and Ur, which were major cities of the Sumerian civilization.
One of the most notable historical figures bearing the name Kaiis was a Sumerian priest and scholar who lived around 2300 BCE. He is credited with compiling one of the earliest known dictionaries, which contained Sumerian and Akkadian words and their translations.
Another famous Kaiis was a Babylonian astronomer who lived during the reign of King Nebuchadnezzar II (604-562 BCE). He made significant contributions to the study of celestial bodies and is believed to have developed one of the earliest known calendars based on lunar cycles.
In the 8th century BCE, a Phoenician merchant named Kaiis was known for his extensive trade routes across the Mediterranean region. He is said to have established settlements in modern-day Tunisia and Spain, facilitating the exchange of goods and cultural influences between the Phoenician civilization and the local populations.
During the 4th century BCE, a Greek philosopher named Kaiis from the city of Ephesus was a student of Plato and a renowned teacher in his own right. He is credited with writing several treatises on ethics, logic, and metaphysics, although only fragments of his works have survived.
In the 1st century CE, a Roman general named Kaiis Cornelius led several successful military campaigns against the Germanic tribes along the Rhine and Danube frontiers. He is remembered for his strategic brilliance and unwavering leadership, which helped secure the borders of the Roman Empire during a time of frequent conflicts.

FAQ
Kaiis: questions and answers
How many people in the U.S. are named Kaiis?
Name Census puts the figure at roughly 13 living Americans. We arrive at this by taking every SSA birth registration for Kaiis 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 26,365,718 US residents.
Is Kaiis a common name?
We classify Kaiis as "Very Rare". It ranks above 33.2% of all first names in the SSA dataset by living bearers. Across the full history of the data, 13 babies have been registered with this name.
When was Kaiis most popular?
The single biggest year for Kaiis was 2004, when 7 babies received the name. The fact that the average living Kaiis is about 14 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 Kaiis in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Kaiis a male name?
Yes, 100.0% of people registered as Kaiis 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 Kaiis still being used today?
Yes. The SSA still recorded Kaiis 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 Kaiis 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.
