Origin
The surname TRUONG originated in Vietnam, and can be traced back to the early 15th century. It is derived from the Vietnamese word "truong," which means "village" or "hamlet." This reflects the name's origins among rural communities in various regions of the country.
One of the earliest known references to the TRUONG name appears in a historical text from the late 15th century, which mentions a village leader named Truong Dinh. This suggests that the name may have initially been associated with local authorities or prominent figures within Vietnamese villages.
By the 16th century, the TRUONG surname had become more widespread, appearing in various administrative records and legal documents from different provinces. Notable individuals from this period include Truong Van Hanh, a skilled carpenter who contributed to the construction of several temples and pagodas in the late 1500s.
In the 17th century, the TRUONG name gained further prominence with the rise of Truong Vinh Ky, a celebrated poet and scholar who served as a high-ranking official in the imperial court. His works, which included collections of poetry and essays, helped to establish the TRUONG name as one associated with literary and intellectual pursuits.
During the 19th century, the TRUONG surname was particularly prevalent in the central and southern regions of Vietnam. One notable figure from this time was Truong Dinh, a renowned military leader who played a crucial role in the resistance against French colonial forces in the late 1800s.
Another significant individual bearing the TRUONG name was Truong Tan Buu, a renowned scientist and educator who made important contributions to the field of nuclear physics in the early 20th century. Born in 1886, he was recognized internationally for his research and served as the president of the Indochina University (now the University of Hanoi) from 1945 to 1951.
Throughout its history, the TRUONG surname has been associated with various occupations, from village leaders and scholars to military figures and scientists. Its enduring presence in Vietnam reflects the country's rich cultural heritage and the deep roots of many family names within its communities.
Demographics
Among Census respondents with the surname Truong, the largest self-reported group is Asian/Pacific Islander at 95.6%. The next largest groups are Two or More Races (2.0%) and White (1.3%).
The bar chart below shows how Truong 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 Truong 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.
