Origin
The surname Doolittle is of English origin, originating in the 13th century. It is derived from the Middle English words "do" meaning to act or perform, and "little" meaning small or insignificant. The name was likely given as a nickname to someone who was considered lazy or idle, perhaps implying they did little work.
One of the earliest recorded instances of the name is found in the Hundredorum Rolls of Bedfordshire in 1273, where it is listed as "Willelmus Dolittle". The Subsidy Rolls of Worcestershire in 1327 also mention a "Johanne Doulittle". These early spellings show the variations in how the name was written at the time.
The Doolittle surname is found in various historical records throughout the centuries. In the 16th century, there are mentions of a John Doolittle in the Parish Registers of St. Margaret's, Westminster, in 1580. The Visitation of Oxfordshire in 1634 also references a Thomas Doolittle who was born in 1630.
One notable bearer of the name was Seth Doolittle (1621-1688), an early settler in New England and a founder of the town of Wallingford, Connecticut. Another was Benjamin Doolittle (1695-1749), a Congregational minister and author from Massachusetts.
In the 18th century, Amos Doolittle (1754-1832) was an American engraver and silversmith known for his work on the first copperplate engravings printed in the United States. Reuben Doolittle (1773-1858) was a prominent businessman and landowner in New York.
Moving into the 19th century, Hezekiah Doolittle (1800-1874) was a notable lawyer and judge in New York, while Everett Doolittle (1846-1929) was a successful businessman and banker in Minnesota.
These are just a few examples of individuals who have borne the Doolittle surname throughout history, showcasing its English roots and its presence across various locations and professions over the centuries.
Demographics
Among Census respondents with the surname Doolittle, the largest self-reported group is White at 87.1%. The next largest groups are Black (4.5%) and Two or More Races (3.4%).
The bar chart below shows how Doolittle 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 Doolittle 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.
