Origin
The surname KWAN originated in China, likely emerging during the Tang Dynasty (618-907 AD). It is derived from the Chinese word 'kwan', meaning 'official' or 'mandarin'. The earliest known references to this name can be found in historical records from the Song Dynasty (960-1279 AD).
One of the earliest recorded individuals with the surname KWAN was Kwan Chung (d. 645 BC), a renowned philosopher and statesman who served as the prime minister of the State of Qi during the Spring and Autumn Period. His writings and teachings greatly influenced the development of Confucian thought.
Another notable figure was Kwan Yu (162-219 AD), a legendary warrior and one of the most famous generals of the Three Kingdoms period. He was deified as the God of War and is revered in Chinese folk religion and Taoism.
During the Tang Dynasty, the KWAN surname was particularly prominent in the region around modern-day Guangdong province. Several members of the imperial clan bore this name, including Kwan Xiu (832-912 AD), a prominent statesman and poet who served as the Chancellor of the Imperial Academy.
In the 13th century, the name appeared in the records of the Mongol Empire, with Kwan Yun-chi (1232-1301 AD) serving as a high-ranking official and diplomat during the reign of Kublai Khan.
The KWAN surname continued to be associated with scholars and officials throughout the Ming (1368-1644 AD) and Qing (1644-1912 AD) dynasties. One notable figure was Kwan Zhongxue (1612-1692 AD), a renowned philosopher and educator who made significant contributions to the Neo-Confucian movement.
As the Chinese diaspora spread across the world, the KWAN surname was carried to various regions, including Southeast Asia, North America, and Europe. While its origins can be traced back to ancient China, the name has become a part of diverse cultural and linguistic traditions over the centuries.
Demographics
Among Census respondents with the surname Kwan, the largest self-reported group is Asian/Pacific Islander at 92.4%. The next largest groups are Two or More Races (3.6%) and White (2.2%).
The bar chart below shows how Kwan 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 Kwan surname at the time of the 2020 Census, not any inherent property of the name itself.

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.
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.
