Origin
Meaning and history of Iassac
The given name Iassac has its origins in ancient Mesopotamia, one of the earliest civilizations in human history. It is believed to be derived from the Akkadian language, which was spoken in Mesopotamia (modern-day Iraq) around the 3rd millennium BCE. The name is thought to have its roots in the Akkadian word "yasaku," which means "to pour out" or "to bestow."
One of the earliest recorded instances of the name Iassac can be found in the Sumerian cuneiform tablets from the city of Ur, dating back to around 2500 BCE. These ancient clay tablets mention an individual named Iassac, who held a prominent position in the city's administrative ranks.
In the ancient Hebrew scriptures, there is a reference to an individual named Iassac ben Shubal, who is mentioned as a skilled artisan and metalworker during the reign of King Solomon in the 10th century BCE. This Iassac is said to have contributed to the construction of the famous Temple in Jerusalem.
During the Hellenistic period, which spanned from the 4th to the 1st century BCE, there are records of a philosopher named Iassac of Cyrene, who was a student of the renowned Greek thinker Aristippus. Iassac is credited with further developing the teachings of the Cyrenaic school of philosophy, which emphasized the pursuit of pleasure as the highest good.
In the 5th century CE, an Armenian historian named Iassac of Taron documented the struggles between the Armenian people and the invading Persian forces. His historical accounts provide valuable insights into the political and cultural landscape of that era.

FAQ
Iassac: questions and answers
How many people in the U.S. are named Iassac?
Name Census puts the figure at roughly 5 living Americans. We arrive at this by taking every SSA birth registration for Iassac 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 68,550,868 US residents.
Is Iassac a common name?
We classify Iassac as "Very Rare". It ranks above 18.2% of all first names in the SSA dataset by living bearers. Across the full history of the data, 5 babies have been registered with this name.
When was Iassac most popular?
The single biggest year for Iassac was 2003, when 5 babies received the name. The fact that the average living Iassac is about 23 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 Iassac in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Iassac a male name?
Yes, 100.0% of people registered as Iassac 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 Iassac still being used today?
Yes. The SSA still recorded Iassac 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 Iassac 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.
