Origin
The surname Chinn is of Anglo-Saxon origin and is derived from the Old English word "ċinn," which means "chin" or "jaw." It is believed to have originated as a nickname for someone with a prominent chin or jawline.
The earliest recorded instance of the Chinn surname dates back to the late 12th century in the county of Sussex, England. The Chinn family can be traced to the village of Chynhult, which is mentioned in the Domesday Book, a survey of England commissioned by William the Conqueror in 1086.
In the 13th century, the name appeared in various forms, such as Chynne, Chynholt, and Chinnok, reflecting the variations in spelling and pronunciation common during that period. The Chinn family later spread to other parts of England, including Gloucestershire and Wiltshire.
One of the earliest recorded individuals with the surname Chinn was Ralph Chynn, who was mentioned in the Assize Rolls of Somerset in 1268. Another notable bearer of the name was John Chinn, a wealthy merchant from London, who lived in the late 14th century.
During the 16th and 17th centuries, the Chinn surname became more widespread, and several members of the family achieved prominence. Sir Henry Chinn (1562-1627) was a successful merchant and served as the Lord Mayor of London in 1624. Thomas Chinn (1605-1677) was a Puritan minister and author who published several religious works.
Another notable figure was Sir John Chinn (1709-1790), a British naval officer who served with distinction during the Seven Years' War and the American Revolutionary War. He was knighted for his service in 1779.
In the 19th century, Edward Chinn (1803-1879) was a prominent British industrialist and entrepreneur who founded the Chinn Mineral Water Company in Harborne, Birmingham. His son, William Chinn (1846-1926), continued the family business and became a successful philanthropist.
While the Chinn surname has its roots in England, it has since spread to other parts of the world, including the United States, Canada, and Australia, carried by immigrants and their descendants.
Demographics
Among Census respondents with the surname Chinn, the largest self-reported group is White at 47.5%. The next largest groups are Asian/Pacific Islander (21.9%) and Black (17.8%).
The bar chart below shows how Chinn 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 Chinn 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 Chinn (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.
