Origin
Meaning and history of Casai
The name Casai is believed to have its origins in the ancient Sumerian language, one of the earliest known written languages in the world, dating back to around 3500 BCE. The Sumerians were a civilization that flourished in the region of Mesopotamia, which is modern-day Iraq. The name Casai is thought to be derived from the Sumerian word "kassu," which means "to be powerful" or "to be mighty."
One of the earliest recorded instances of the name Casai can be found in the Epic of Gilgamesh, an ancient Mesopotamian epic poem that dates back to the third millennium BCE. In this epic, Casai is mentioned as the name of a mighty warrior who fought alongside the legendary hero Gilgamesh. This suggests that the name Casai was associated with strength and valor in ancient Sumerian culture.
During the height of the Babylonian Empire, which ruled over Mesopotamia from around 1900 BCE to 539 BCE, the name Casai gained further prominence. Babylonian records mention several individuals with this name, including Casai the Scribe, a renowned scholar and writer who lived during the reign of King Nebuchadnezzar II in the 6th century BCE.
As civilizations rose and fell in the ancient world, the name Casai spread to other regions and cultures. In ancient Greece, there was a philosopher named Casai of Miletus, who lived in the 6th century BCE and was known for his contributions to the study of astronomy and mathematics. In ancient Rome, there are records of a Roman general named Casai Valerius, who served under the emperor Trajan in the early 2nd century CE and led successful military campaigns against the Parthians.
Over the centuries, the name Casai has been borne by various notable individuals, including Casai ibn Musa, a 9th-century Persian mathematician and astronomer who made significant contributions to the development of algebra and trigonometry. Another prominent figure was Casai al-Rumi, a 13th-century Sufi mystic and poet from Anatolia, whose works explored themes of love, spirituality, and the pursuit of divine knowledge.
As the name Casai traveled across different cultures and languages, its spelling and pronunciation often underwent slight variations. However, its association with strength, power, and wisdom remained a consistent thread throughout its long history, making it a name that has endured for millennia.

FAQ
Casai: questions and answers
How many people in the U.S. are named Casai?
Name Census puts the figure at roughly 14 living Americans. We arrive at this by taking every SSA birth registration for Casai 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 24,482,453 US residents.
Is Casai a common name?
We classify Casai as "Very Rare". It ranks above 34% of all first names in the SSA dataset by living bearers. Across the full history of the data, 14 babies have been registered with this name.
When was Casai most popular?
The single biggest year for Casai was 2023, when 8 babies received the name. The fact that the average living Casai 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 Casai in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Casai a male name?
Yes, 100.0% of people registered as Casai 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 Casai still being used today?
Yes. The SSA still recorded Casai 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 Casai 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.
