Origin
The surname CHOU has its origins in China, dating back to the Zhou Dynasty (1046–256 BC). It is derived from the Chinese character 周, which means "surrounding" or "encompassing." The Zhou Dynasty was a pivotal period in Chinese history, during which the concept of the Mandate of Heaven was developed, establishing the legitimacy of the ruling house based on moral virtue.
One of the earliest recorded individuals with the surname CHOU was Zhou Gong (周公), the Duke of Zhou, who lived in the 11th century BC. He was a prominent figure during the Western Zhou Dynasty and is credited with establishing many of the governmental and social structures that shaped Chinese civilization.
The CHOU surname has been associated with several notable figures throughout Chinese history. Zhou Dunyi (周敦颐, 1017–1073) was a renowned Neo-Confucian philosopher and one of the founders of the Lixue (理学) school of thought. His works, such as the "Taiji Tushuo" (太极图说), were highly influential in the development of Neo-Confucian cosmology.
Another prominent individual with the CHOU surname was Zhou Enlai (周恩来, 1898–1976), a Chinese revolutionary and statesman who served as the first Premier of the People's Republic of China from 1949 until his death. He played a crucial role in the establishment of the Communist government and was instrumental in shaping China's foreign policy during the Cold War era.
In the realm of literature, Zhou Shuren (周树人, 1881–1936), better known by his pen name Lu Xun (鲁迅), was a leading figure in the May Fourth Movement and is considered one of the most influential modern Chinese writers. His works, such as the short story collections "Nahan" (呐喊) and "Panghuang" (朋黄), exposed the social ills of traditional Chinese society and advocated for cultural and political reform.
The CHOU surname has also been associated with various place names in China, such as Zhouxian (周县) in Hebei Province and Zhoushan (舟山) in Zhejiang Province. These place names often derive from the Zhou Dynasty or are related to the surname's meaning of "surrounding" or "encompassing."
While the CHOU surname has a rich history and cultural significance in China, it has also gained recognition worldwide, with individuals bearing this surname making contributions across various fields, from politics and philosophy to literature and the arts.
Demographics
Among Census respondents with the surname Chou, the largest self-reported group is Asian/Pacific Islander at 92.5%. The next largest groups are Two or More Races (3.4%) and White (2.6%).
The bar chart below shows how Chou 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 Chou 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.
