Origin
The surname BILES has its origins in England, dating back to the medieval period. It is believed to have originated from a place name, specifically a location called "Biles" or "Byles" in the county of Gloucestershire. This place name itself is derived from the Old English words "bil" or "byll," meaning a hill or ridge, and "leah," meaning a clearing or meadow.
One of the earliest recorded instances of the surname BILES can be found in the Subsidy Rolls of Worcestershire from 1327, which mentions a certain "John de Byles." The Subsidy Rolls were tax records kept by the English government during the 14th century.
Another notable historical reference to the surname BILES comes from the Feet of Fines for Gloucestershire in 1541, which documents a land transaction involving a person named "Thomas Byles." The Feet of Fines were legal records of land transfers and property disputes.
In the 16th century, the BILES surname appears to have been primarily concentrated in the counties of Gloucestershire and Worcestershire, with some variations in spelling such as "Byles" and "Billes." This is evident in parish records and legal documents from that period.
One of the earliest recorded individuals with the surname BILES was William Biles, a member of the Society of Friends (Quakers) who was born in Gloucestershire around 1640. He was known for his active involvement in the Quaker community and his efforts in promoting religious tolerance.
Another notable figure was John Biles, a prominent architect and builder who lived in the late 17th and early 18th centuries. He was responsible for designing and constructing several notable buildings in the city of Bristol, including the impressive St. Michael's Hill Shot Tower in 1719.
In the 19th century, a family of BILES was recorded as residing in the village of Painswick in Gloucestershire. Among them was Henry Biles (1805-1881), a respected local farmer and landowner who played an active role in the community.
The surname BILES also has ties to the United States, with several individuals bearing this name immigrating from England in the 17th and 18th centuries. One such individual was Thomas Biles, who arrived in Pennsylvania in 1682 and settled in what is now Bucks County.
Another notable figure with the BILES surname was James Biles (1825-1901), a British-born engineer and inventor who made significant contributions to the development of early steam engines and boilers. He held several patents and was widely recognized for his innovative designs.
Demographics
Among Census respondents with the surname Biles, the largest self-reported group is White at 72.2%. The next largest groups are Black (16.8%) and Two or More Races (5.5%).
The bar chart below shows how Biles 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 Biles 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.
