Origin
The surname Cha has its origins in China, where it is a relatively common family name. It is believed to have originated from the northern regions of the country during the Tang Dynasty (618-907 AD). The name is derived from the Chinese word "cha," which means "fork" or "branch," and it may have been used to describe someone who lived near a forked river or road.
One of the earliest recorded instances of the name Cha can be found in the Tang Dynasty genealogical records known as the "Jiu Tangshu" (Old Book of Tang), which mentions a family with this surname. During the Song Dynasty (960-1279 AD), the name Cha was also documented in the "Songshi" (History of Song), a historical text that chronicled the events and people of that era.
In the 13th century, the Mongolian leader Kublai Khan established the Yuan Dynasty (1271-1368) in China, and many people with the surname Cha are believed to have migrated to other parts of Asia during this period. For example, the Cha family has a long history in Korea, where they are known as "Cha-ssi."
One notable figure with the surname Cha was Cha Yi (1292-1366), a Korean scholar and poet who served as a high-ranking official during the Goryeo Dynasty. Another prominent individual was Cha Hak-yeon (1563-1644), a Korean Neo-Confucian scholar and writer who was known for his works on ethics and philosophy.
In more recent history, Cha Bum-kun (1953-2023) was a South Korean football player and manager who played for the national team and several clubs in Germany. He is considered one of the greatest Asian footballers of all time.
Another notable figure with the surname Cha is Cha In-pyo (1835-1906), a Korean calligrapher and painter who was renowned for his innovative techniques and his contributions to the development of Korean calligraphy.
Cha Tsu Kong (1882-1948) was a Chinese educator and politician who played a significant role in the establishment of modern educational systems in China. He served as the Minister of Education and was a prominent figure in the early years of the Republic of China.
While the surname Cha has its roots in China, it has spread to other parts of Asia and even to other continents through migration and cultural exchange. However, it remains a prominent family name in East Asian countries, particularly in China, Korea, and parts of Southeast Asia.
Demographics
Among Census respondents with the surname Cha, the largest self-reported group is Asian/Pacific Islander at 92.7%. The next largest groups are White (2.3%) and Hispanic (2.3%).
The bar chart below shows how Cha 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 Cha 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 Cha (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.
