Origin
Meaning and history of Cj
The name Cj has its origins in the Latin language, dating back to ancient Roman times. It is a shortened form of the name Caius, which was a popular Roman praenomen, or personal name, during the Roman Republic and Empire periods.
The name Caius is derived from the Latin word "gaudere," which means "to rejoice" or "to be glad." This suggests that Cj may have been used as a name to express joy or happiness for a newborn child. It was a common practice in ancient Roman society to choose names with positive meanings or associations.
One of the earliest recorded instances of the name Caius can be found in the writings of ancient Roman historians and philosophers, such as Cicero and Tacitus. They mention several prominent figures bearing the name, including Gaius Julius Caesar, the famous Roman leader and military strategist who lived from 100 BC to 44 BC.
Another notable figure was Gaius Suetonius Tranquillus, a Roman historian who lived from around 69 AD to 122 AD. He is best known for his work "De Vita Caesarum," which chronicled the lives of the first twelve Roman emperors.
In the medieval period, the name Caius was sometimes Latinized as Gaius or Gajus, but it remained relatively uncommon in most parts of Europe. However, it did see some use in Italy, where it was rendered as Gaio or Cajo.
During the Renaissance, the name experienced a revival, particularly among humanist scholars and intellectuals who admired classical Roman culture. One notable figure was Gaius Sallustius Crispus, better known as Sallust, a Roman historian and politician who lived from 86 BC to 35 BC.
In more recent history, the shortened form Cj has been used as a given name, although it remains relatively uncommon. One notable bearer was Cj Wilcox, an American professional basketball player who was born in 1990 and played in the NBA for several teams, including the Los Angeles Clippers and the Orlando Magic.
Overall, while the name Cj may not be as widely used today as it was in ancient Roman times, it has a rich historical legacy and associations with joy, gladness, and classical Roman culture.

FAQ
Cj: questions and answers
How many people in the U.S. are named Cj?
Name Census puts the figure at roughly 1,499 living Americans. We arrive at this by taking every SSA birth registration for Cj 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 228,655 US residents.
Is Cj a common name?
We classify Cj as "Rare". It ranks above 92.4% of all first names in the SSA dataset by living bearers. Across the full history of the data, 1,529 babies have been registered with this name.
When was Cj most popular?
The single biggest year for Cj was 1994, when 55 babies received the name. The fact that the average living Cj 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 Cj in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Cj a male name?
Yes, 91.3% of people registered as Cj 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 Cj still being used today?
Yes. The SSA still recorded Cj 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 Cj 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.
