Origin
The surname Warren is of Anglo-Norman origin, deriving from the Old French word "warrene" meaning "animal enclosure" or "hunting preserve". It is believed to have originated in England after the Norman Conquest of 1066, when many Norman nobles and their followers settled in the country and were granted lands by William the Conqueror.
The earliest recorded instances of the surname can be traced back to the 12th century, with a mention of a William de Warenne in the Domesday Book of 1086, which was a survey of land ownership in England commissioned by William the Conqueror. The name is also found in various medieval records and manuscripts, such as the Pipe Rolls and the Curia Regis Rolls.
One of the most notable bearers of the surname was William de Warenne, Earl of Surrey (c. 1166-1240), a powerful Norman nobleman who played a significant role in the Barons' War against King John. Another prominent figure was John de Warenne, Earl of Surrey (c. 1286-1347), who fought in the Scottish Wars of Independence and the Hundred Years' War.
In addition to its association with noble families, the surname Warren was also derived from various place names in England, such as Warren in Somerset, Warrington in Lancashire, and Warrener in Northamptonshire. These place names often referred to areas where game was kept for hunting.
Other notable individuals with the surname Warren include Joseph Warren (1741-1775), an American Revolutionary leader who was killed at the Battle of Bunker Hill, and Mercy Otis Warren (1728-1814), an American writer and playwright who was a prominent figure in the American Revolution. In the 19th century, Samuel P. Warren (1809-1867) was an American jurist and author who wrote several influential legal treatises.
The Warren surname has also been borne by several notable artists and writers, including Robert Penn Warren (1905-1989), an American poet and novelist who won the Pulitzer Prize for fiction, and Mercy Warren (1805-1828), an American novelist and playwright who was a pioneer of early American literature.
Demographics
Among Census respondents with the surname Warren, the largest self-reported group is White at 67.3%. The next largest groups are Black (23.5%) and Two or More Races (4.5%).
The bar chart below shows how Warren 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 Warren surname at the time of the 2020 Census, not any inherent property of the name itself.

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.
