Origin
The surname PENG has its origins in China, where it dates back to ancient times. It is derived from the Chinese word "peng," which means "level" or "flat," suggesting that the name may have been given to families who lived in regions with flat terrain or open plains.
One of the earliest recorded instances of the PENG surname can be found in the historical records of the Tang Dynasty (618-907 AD), where it was mentioned as a prominent family name in the region of present-day Sichuan Province. During this period, the PENG family played a significant role in local governance and politics.
In the Song Dynasty (960-1279 AD), the PENG surname gained further prominence with the rise of PENG Daya (945-1005), a renowned scholar and philosopher who made significant contributions to the development of Neo-Confucianism. His writings and teachings influenced generations of scholars and thinkers in China.
The Ming Dynasty (1368-1644) also saw the PENG surname associated with notable figures, such as PENG Sunyu (1615-1677), a prominent military leader and strategist who played a crucial role in the defense of China against the Manchu invasion.
In the realm of literature, PENG Cheng (1938-2020) was a celebrated Chinese novelist and screenwriter, known for his realistic depictions of urban life in contemporary China. His novels, such as "The Wandering Falcon" and "The Scorching Sun," received critical acclaim and brought him international recognition.
Another notable figure with the PENG surname was PENG Dehuai (1898-1974), a prominent military leader who played a significant role in the Chinese Civil War and the Korean War. He served as the Vice-Premier of the People's Republic of China from 1954 to 1959.
While the PENG surname has its roots in China, it has also spread to other parts of the world through migration and cultural exchange. In Taiwan, for instance, there is a sizable population with the PENG surname, reflecting the shared cultural heritage with mainland China.
Demographics
Among Census respondents with the surname Peng, the largest self-reported group is Asian/Pacific Islander at 92.4%. The next largest groups are Hispanic (3.2%) and White (2.6%).
The bar chart below shows how Peng 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 Peng 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.
