Origin
Meaning and history of Json
The given name Json is believed to have originated from the ancient Sumerian language, which was spoken in the region of Mesopotamia (modern-day Iraq) around the 3rd millennium BCE. It is thought to be derived from the Sumerian word "jasun," which loosely translates to "the one who brings order."
In some of the earliest known cuneiform tablets and clay tablets from the Sumerian civilization, there are references to individuals bearing names similar to Json. It is speculated that these names were given to individuals who played important roles in organizing and maintaining the intricate systems of writing, record-keeping, and administration that were crucial to the functioning of these ancient city-states.
The first recorded instance of the name Json dates back to around 2500 BCE, where it appears in a clay tablet detailing the names of scribes and administrators in the city of Uruk. One notable individual from this time period was Json of Uruk, who is believed to have been a high-ranking official responsible for overseeing the distribution of grain and other resources.
As the influence of Sumerian culture spread throughout Mesopotamia and the Near East, the name Json also gained popularity in other ancient civilizations, such as the Akkadians, Babylonians, and Assyrians. It was often associated with individuals who held positions of authority or were skilled in organizing and managing complex systems.
In the later centuries BCE, there are records of a Json of Babylon, who was a renowned astronomer and mathematician. His contributions to the study of celestial bodies and the development of early calendars were significant for the advancement of ancient science.
During the classical era, the name Json was also found in ancient Greek records, likely adopted through cultural exchanges and trade between the Greeks and the civilizations of the Near East. One notable figure was Json of Ephesus, a philosopher and teacher who lived in the 4th century BCE and was known for his teachings on ethics and virtue.
In the later centuries CE, the name Json appeared in various regions influenced by the spread of Christianity. One notable figure was Json of Alexandria, a 5th-century monk and scholar who played a significant role in the preservation and translation of ancient texts, contributing to the transmission of knowledge during the medieval period.
It is important to note that the name Json, while having ancient origins, has undergone various phonetic and orthographic changes over the centuries as it passed through different languages and cultures. The spelling and pronunciation may have varied across regions and time periods.

FAQ
Json: questions and answers
How many people in the U.S. are named Json?
Name Census puts the figure at roughly 294 living Americans. We arrive at this by taking every SSA birth registration for Json 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 1,165,831 US residents.
Is Json a common name?
We classify Json as "Very Rare". It ranks above 79% of all first names in the SSA dataset by living bearers. Across the full history of the data, 302 babies have been registered with this name.
When was Json most popular?
The single biggest year for Json was 1996, when 49 babies received the name. The fact that the average living Json is about 29 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 Json in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Json a male name?
Yes, 100.0% of people registered as Json 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 Json still being used today?
Yes. The SSA still recorded Json 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 Json 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.
