Origin
The surname Zhou has its origins in China, with records of the name dating back to the Shang Dynasty (1600-1046 BC). It is considered one of the oldest and most prominent Chinese family names. The name is derived from the ancient state of Zhou, located in present-day Shaanxi Province, which was a major power during the Zhou Dynasty (1046-256 BC).
During the Zhou Dynasty, the name Zhou was closely associated with the ruling royal family and nobility. Several important historical figures bore this surname, including Zhou Gong, a renowned statesman and philosopher who is credited with establishing the principles of the Rites of Zhou, a comprehensive guide to governance and social norms.
The earliest recorded instances of the Zhou surname can be found in various ancient texts, such as the Shiji (Records of the Grand Historian) by Sima Qian, a monumental historical work completed in the 1st century BC. This text contains detailed accounts of the Zhou royal lineage and their influential role in shaping the course of Chinese history.
One of the most famous individuals with the Zhou surname was Zhou Enlai (1898-1976), a prominent Chinese communist revolutionary and statesman who served as the first Premier of the People's Republic of China from 1949 until his death. His significant contributions to the establishment and development of modern China have cemented his legacy as one of the country's most influential political figures.
Another notable figure was Zhou Youguang (1906-2017), a renowned linguist and economist who is best known for his instrumental role in developing the Pinyin romanization system for Mandarin Chinese, which has become an international standard for transcribing Chinese characters into the Latin alphabet.
The Zhou surname has also been associated with various place names throughout China's history. For instance, the ancient state of Zhou was located in what is now known as the Zhou County in Shaanxi Province, which continues to bear the name to this day.
Other prominent individuals with the Zhou surname include Zhou Tienyi (1914-1999), a Chinese mathematician and educator who made significant contributions to the field of algebraic geometry, and Zhou Xuan (1918-1957), a celebrated Chinese writer and poet known for his innovative literary works during the mid-20th century.
Demographics
Among Census respondents with the surname Zhou, the largest self-reported group is Asian/Pacific Islander at 96.3%. The next largest groups are White (2.3%) and Two or More Races (0.6%).
The bar chart below shows how Zhou 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 Zhou 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 Zhou (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.
