Origin
The surname NAMGUNG has its origins in Korea, tracing back to the medieval period. It is derived from the Korean word "nam," meaning "south," and "gung," meaning "province" or "region." This suggests that the name was likely associated with individuals or families who hailed from southern regions of the Korean peninsula.
One of the earliest recorded references to the NAMGUNG surname can be found in the Goryeo Dynasty annals, which spanned from 918 to 1392 CE. These historical documents mention several prominent figures bearing this surname, indicating its established presence during that time.
In the late 14th century, a scholar and government official named NAMGUNG Gon (1320-1392) gained recognition for his contributions to the establishment of the Joseon Dynasty, which succeeded the Goryeo Dynasty. His writings and political influence left a lasting impact on Korean society.
During the Joseon Dynasty (1392-1897), the NAMGUNG surname continued to be associated with scholars, officials, and influential families. One notable figure was NAMGUNG Won (1577-1626), a renowned Confucian scholar and philosopher who made significant contributions to Neo-Confucian thought in Korea.
In the 19th century, NAMGUNG Hyeon (1820-1898) was a prominent scholar and calligrapher who played a crucial role in preserving and promoting traditional Korean arts and culture during a period of modernization and foreign influences.
Moving into the early 20th century, NAMGUNG Eok (1863-1939) was a prominent educator and independence activist who fought against Japanese colonial rule in Korea. His efforts and advocacy for Korean independence left a lasting legacy.
Throughout its history, the NAMGUNG surname has been associated with various regions and place names in Korea, reflecting the geographical roots of different branches of the family. However, the exact origins and connections to specific locations remain a subject of ongoing research and interpretation by historians and genealogists.
Demographics
Among Census respondents with the surname Namgung, the largest self-reported group is Asian/Pacific Islander at 93.3%. The next largest groups are Black (2.9%) and White (1.9%).
The bar chart below shows how Namgung 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 Namgung 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.
