Origin
The surname DUONG is believed to have originated in Vietnam, where it has been a common family name for centuries. It is derived from the Vietnamese word "duong," which means "path" or "road." This suggests that the name may have been initially associated with those who lived along a particular road or path, or perhaps with those who worked as guides or travelers.
DUONG is a romanized spelling of the Vietnamese name, which is traditionally written using Chinese characters. In ancient times, the name was likely written using various Chinese characters that carried similar meanings related to paths or roads.
While specific historical records documenting the earliest uses of the name DUONG are scarce, it is believed to have been a prominent family name in Vietnam as early as the 11th century, during the Ly Dynasty. Some scholars suggest that the name may have originated even earlier, during the period of Chinese cultural influence in Vietnam before the nation gained independence.
One of the earliest recorded individuals with the surname DUONG was Duong Van Nga, a prominent military commander who lived in the 13th century during the Tran Dynasty. He played a significant role in defending Vietnam against Mongol invasions and is celebrated as a national hero.
In the 15th century, Duong Nhat Le was a famous poet and scholar who contributed significantly to the development of Vietnamese literature and philosophy. His works, including the celebrated "Quy Du Trac" (The Journey to the West), have been widely studied and admired.
During the 17th century, Duong Quy Phi was a renowned female poet and concubine of Lord Nguyen Phuc Lan, a powerful ruler in southern Vietnam. Her poetry and literary works have been celebrated for their beauty and emotional depth.
In more recent history, Duong Van Minh was a prominent military leader who served as the last president of South Vietnam before the Fall of Saigon in 1975. He played a significant role in the Vietnam War and the eventual reunification of the country.
Another notable figure with the surname DUONG was Duong Thu Huong, a contemporary Vietnamese novelist and dissident. Her works, which often criticized the Vietnamese government, gained international recognition and earned her numerous literary awards.

Demographics
Among Census respondents with the surname Duong, the largest self-reported group is Asian/Pacific Islander at 95.7%. The next largest groups are Two or More Races (1.8%) and White (1.3%).
The bar chart below shows how Duong 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 Duong 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.
