Origin
Meaning and origin of Dimond
The surname Dimond is believed to have originated in England, with records dating back to the 12th century. It is derived from the Anglo-Norman French word "diaman," meaning "diamond," which in turn comes from the ancient Greek word "adamas," meaning "invincible" or "unconquerable."
The name Dimond was likely initially used as a nickname or a descriptive surname, referring to someone who possessed qualities associated with diamonds, such as strength, resilience, or perhaps a sparkling personality. It may have also been given to someone who worked with or traded in diamonds.
One of the earliest recorded instances of the name Dimond can be found in the Pipe Rolls of Gloucestershire, dated 1189, which mentions a Robert Dimond. Another early record is the Hundred Rolls of Oxfordshire from 1273, which lists a Walter Dimond.
In the 14th century, the name appeared in various spellings, such as Dyamond, Diamont, and Diamaund, reflecting the evolving nature of English spelling during that time. For instance, the Lay Subsidy Rolls of Worcestershire in 1327 include a John Diamont.
The Dimond surname has been associated with several notable individuals throughout history, such as Sir Nathaniel Dimond (1590-1661), an English merchant and Member of Parliament during the reign of Charles I. Another prominent figure was John Dimond (1675-1745), a British merchant and Member of Parliament for Bristol.
In the 18th century, Robert Dimond (1719-1777) was a renowned English author and playwright, best known for his satirical works. One of his contemporaries was William Dimond (1780-1837), an English dramatist and actor who wrote several successful plays.
The 19th century saw the rise of William Dimond (1837-1904), a British naval officer and explorer who participated in several Arctic expeditions and made significant contributions to the exploration of the Canadian Arctic.
These examples illustrate the longstanding presence and diverse backgrounds of individuals bearing the surname Dimond throughout the centuries.

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 Dimond surname at the time of the 2020 Census, not any inherent property of the name itself.

Is this page using the latest Census data?
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 Dimond (2000, 2010, 2020).
Does the Census include every surname?
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.
Why don't the ancestry percentages always add up to exactly 100%?
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.
