Origin
The surname DAIL is of English origin, tracing its roots back to the Middle Ages. It likely emerged as a locational name, derived from a place name such as Dale or Dail, referring to a valley or dell.
One of the earliest recorded instances of the name can be found in the Domesday Book of 1086, where it appears as "de Dail," indicating an individual hailed from a place called Dail. This locational prefix "de" was commonly used in Norman England to denote one's place of origin.
Throughout the medieval period, the name DAIL appeared in various spellings, including Dayle, Daille, and Deyle, reflecting the fluid nature of spelling practices at the time. Some of these variations may have been influenced by French or Norman pronunciations.
In the 13th century, a notable figure bearing the name was Sir William Dail, a knight who fought in the Crusades and participated in the siege of Acre in 1191. His name is recorded in chronicles detailing the campaigns of King Richard I (the Lionheart).
During the Tudor era, one John Dail (1470-1538) was a prominent merchant and alderman in the city of London. He was known for his philanthropic efforts, including the establishment of a charity school in his hometown of Stratford-upon-Avon.
Another individual of note was Elizabeth Dail (1594-1672), a Puritan writer and poet who authored several religious works, including "The Spiritual Voyage" and "Meditations on the Lord's Prayer."
In the 18th century, Samuel Dail (1718-1789) was a renowned architect who designed several churches and public buildings in London, including St. George's Church in Bloomsbury and the Old Bailey courthouse.
During the Victorian era, Charles Dail (1829-1901) was a famous explorer and naturalist who traveled extensively in Africa and wrote several books detailing his expeditions and discoveries of new plant and animal species.
While the surname DAIL may have originated from a specific place name, its meaning evolved to encompass a broader association with valleys or dells, reflecting the rural roots of many English surnames.
Demographics
Among Census respondents with the surname Dail, the largest self-reported group is White at 83.0%. The next largest groups are Black (8.6%) and Two or More Races (3.9%).
The bar chart below shows how Dail 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 Dail 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 Dail (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.
