Origin
Meaning and origin of Jun
The surname JUN originates from China and has its roots in the Mandarin Chinese language. It is believed to have emerged during the Tang Dynasty, which ruled from 618 to 907 AD. The name JUN is derived from the Chinese word "jun," which means "truth" or "noble." It was often given as a surname to individuals who were considered honest, virtuous, or of high social standing.
One of the earliest recorded instances of the surname JUN can be found in the Tang Dynasty's official records, where it is mentioned in reference to a noble family from the city of Chang'an, the capital of the Tang Empire. This family was known for their integrity and service to the imperial court.
During the Song Dynasty (960-1279 AD), the JUN surname gained further prominence. In the year 1086, a scholar named JUN Qingzhi was appointed as a high-ranking official in the imperial government, and his achievements were documented in the historical records of the time.
In the 13th century, a military general named JUN Wenzhen played a significant role in defending the Song Dynasty against the Mongol invasions. His bravery and strategic prowess earned him a place in the annals of Chinese history.
As the dynasties changed and empires rose and fell, the JUN surname continued to be associated with individuals of notable character and accomplishments. One notable figure was JUN Xizhai, a renowned artist and calligrapher who lived during the Ming Dynasty (1368-1644 AD).
Another prominent individual with the surname JUN was a 16th-century scholar and philosopher named JUN Zhi. His works on Confucian philosophy and ethics were widely studied and influential during his time.
It is worth noting that variations of the JUN surname, such as JUEN and JUAN, can be found in other regions of China and among Chinese diaspora communities around the world. These variations likely emerged due to regional dialects and linguistic adaptations over time.
Throughout its history, the surname JUN has been associated with individuals who have made significant contributions to various fields, including literature, art, philosophy, and military strategy. While the name may have evolved and taken on different forms, its underlying meaning of truth, nobility, and integrity has remained a consistent thread.

The bar chart below shows how Jun bearers described their own race and ethnicity on the 2020 Census form. The Census Bureau groups responses into six broad categories: White, Black or African American, Hispanic or Latino, Asian and Pacific Islander, American Indian and Alaska Native, and Two or More Races. When a category has too few respondents for a given surname, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.
Percentages are shown for every Census year so the breakdown stays comparable over time. When the source file also includes raw headcounts, Name Census shows those alongside the percentages in the legend.
Keep in mind that these are self-reported numbers. A person's surname does not determine their race or ethnicity, and the distribution you see here reflects the specific population who happened to carry the Jun surname at the time of the 2020 Census, not any inherent property of the name itself.

Is this page using the latest Census data?
Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Jun (2000, 2010, 2020).
Does the Census include every surname?
No. The Census Bureau only publishes surnames that appeared at least 100 times in a given decennial Census. That means very rare surnames are excluded entirely, and a surname can appear in one Census release but disappear from a later one if it falls below the reporting threshold.
Why don't the ancestry percentages always add up to exactly 100%?
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy. For 2020, the Bureau also published raw group counts rather than direct percentages, so Name Census converts those counts back into shares for comparability across census years.
