Origin
The surname DEWITT originated in the Netherlands during the Middle Ages. It is derived from the Dutch words "de" meaning "the" and "Witt" meaning "white". The name likely referred to someone with white or fair hair or complexion.
One of the earliest recorded instances of the DEWITT surname dates back to the 13th century in Amsterdam. It appeared in municipal records and property deeds of the time, sometimes spelled as "de Witte" or "de Wit". Many of the earliest bearers of this name were from the provinces of North and South Holland.
In the 16th century, the DEWITT name gained prominence with Cornelis de Witt (1623-1672), a renowned Dutch statesman and Grand Pensionary of Holland. He played a crucial role in the Dutch Golden Age and the Anglo-Dutch Wars against England.
Another notable historical figure was Johan de Witt (1625-1692), the younger brother of Cornelis. He was a highly influential Dutch politician who served as the Grand Pensionary of Holland from 1653 to 1672. Both brothers were tragically lynched by an angry mob in The Hague in 1672.
In the 17th century, the DEWITT surname also appeared in English records, likely due to Dutch immigration and trade connections with Britain. One early bearer was Emanuel de Witt (1617-1692), a Dutch-born merchant and landowner who settled in London.
During the American Colonial era, several individuals with the DEWITT surname made their mark. Simeon DeWitt (1756-1834) was a prominent surveyor and cartographer who served as the Surveyor General of the Continental Army under George Washington.
Another notable figure was Jacob DeWitt (1784-1843), a lawyer and politician from New York who served as a U.S. Senator and Mayor of New York City. He was also a member of the influential DeWitt family of New York, which included several prominent politicians and landowners.
Demographics
Among Census respondents with the surname Dewitt, the largest self-reported group is White at 85.1%. The next largest groups are Black (6.4%) and Two or More Races (3.8%).
The bar chart below shows how Dewitt 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 Dewitt 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 Dewitt (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.
