Origin
The surname Cammack is of English origin, derived from the Old English words "cammoc" and "cam," meaning "crooked" or "bent." It likely originated in areas of England where these words were commonly used to describe the local landscape or geographic features.
One of the earliest recorded instances of the name Cammack can be found in the Domesday Book of 1086, where it appears as "Camoc" or "Camoch." This suggests that the name was already in use during the 11th century in parts of England.
In the 13th century, variations of the name, such as "Camac" and "Cammac," began to appear in various historical records and documents from regions like Yorkshire and Lincolnshire. These variations may have been influenced by the local dialects and pronunciation differences in different parts of the country.
One notable bearer of the surname Cammack was Sir John Cammack (c. 1460-1537), a wealthy English merchant and politician who served as Sheriff of London in 1525. He was a prominent figure in the City of London during the reign of King Henry VIII.
Another individual with the Cammack surname was William Cammack (1612-1681), an English Puritan minister and author who emigrated to New England in the 17th century. He served as a minister in several towns in Massachusetts and published several religious works.
In the 18th century, the Cammack surname was also found in Scotland, where variations like "Cammock" and "Cammick" were used. One example is Thomas Cammick (1725-1802), a Scottish mathematician and astronomer who contributed to the development of nautical almanacs and navigational techniques.
The name Cammack may also have been influenced by or derived from certain place names in England, such as Camock in Yorkshire or Cammock in Staffordshire. These place names likely had similar linguistic roots and may have contributed to the spread and evolution of the surname.
Other notable individuals with the Cammack surname include John Cammack (1770-1859), an English artist and engraver known for his landscape paintings and etchings, and James Cammack (1834-1909), an American businessman and politician who served as mayor of Salt Lake City, Utah, in the late 19th century.
Demographics
Among Census respondents with the surname Cammack, the largest self-reported group is White at 76.9%. The next largest groups are Black (13.8%) and Two or More Races (4.2%).
The bar chart below shows how Cammack 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 Cammack 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 Cammack (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.
