Origin
The surname Mao originated in China, with records indicating its use dating back to the 4th century AD during the Eastern Jin Dynasty. This name is believed to be derived from the ancient Chinese word "mao," which means "hair" or "fur." It may have originally referred to someone with a distinctive hairstyle or perhaps a person who worked with animal fur or hair.
One of the earliest known references to the name Mao can be found in the historical text "Book of Jin," which documents the lives of prominent figures during the Jin Dynasty. This work mentions a scholar and calligrapher named Mao Xing, who lived from 334 to 398 AD and was renowned for his exceptional penmanship and literary contributions.
During the Tang Dynasty, which ruled from 618 to 907 AD, the Mao surname gained prominence in various regions of China, particularly in the areas now known as Henan, Shandong, and Anhui provinces. Records from this period show several notable individuals bearing the Mao name, including the poet Mao Ying (625-705 AD) and the military strategist Mao Sui (589-644 AD).
In the Song Dynasty (960-1279 AD), the Mao surname was well-established in the region of Shandong, where a prominent branch of the family resided in the city of Linzi (now part of Zibo). One of the most famous individuals from this era was the scholar and philosopher Mao Qiling (1090-1155 AD), who made significant contributions to the Neo-Confucian movement.
During the Ming Dynasty (1368-1644 AD), the Mao surname continued to be well-represented among the scholarly and literary elite. One notable figure was Mao Jin (1599-1659 AD), a renowned playwright and author who wrote several influential works, including the play "The Peony Pavilion."
In more recent history, the most famous individual bearing the Mao surname is undoubtedly Mao Zedong (1893-1976 AD), the founding leader of the People's Republic of China and a pivotal figure in the Chinese Communist Revolution. Other notable individuals with the Mao surname include the writer and activist Mao Dun (1896-1981 AD) and the contemporary artist Mao Xuhui (born 1956).
Demographics
Among Census respondents with the surname Mao, the largest self-reported group is Asian/Pacific Islander at 93.1%. The next largest groups are White (2.7%) and Two or More Races (2.4%).
The bar chart below shows how Mao 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 Mao surname at the time of the 2020 Census, not any inherent property of the name itself.

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Mao (2000, 2010, 2020).
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.
