Origin
The surname Miley originates from England and is thought to have derived from the Old English words "mil" meaning "mile" and "leah" meaning "a clearing in a forest or wood". It is believed to have initially referred to someone who lived near a mile marker or a mile from a particular location.
One of the earliest recorded instances of the name Miley can be found in the Domesday Book of 1086, which mentions a landowner named Mileleah in Berkshire. The name appeared in various forms, such as Mileley, Milelaie, and Mylaie, in medieval records across different counties in England.
In the 13th century, a notable individual named John Miley was recorded as a landowner in the village of Farnham, Surrey. Another early bearer of the name was William Myley, who was mentioned in the Pipe Rolls of Gloucestershire in 1275.
During the 16th and 17th centuries, the Miley surname was found in various parts of England, particularly in counties like Yorkshire, Lancashire, and Cheshire. One prominent figure from this period was Robert Miley, a wealthy merchant from London who lived between 1580 and 1647.
In the 18th century, the Miley family had a presence in the county of Staffordshire, where a branch of the family owned a significant estate. A notable member of this family was Sir Thomas Miley (1710-1789), a landowner and magistrate who played an active role in local affairs.
Another individual of note was Elizabeth Miley (1766-1854), a renowned author and poet from Yorkshire, whose works were widely acclaimed during her lifetime.
As the Miley family dispersed across different regions of England over the centuries, variations in the spelling of the name emerged, including Myley, Mylie, Mileigh, and Milie. However, the core meaning and origins of the surname remained rooted in its Old English etymology.
Demographics
Among Census respondents with the surname Miley, the largest self-reported group is White at 79.1%. The next largest groups are Black (13.5%) and Two or More Races (3.4%).
The bar chart below shows how Miley 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 Miley 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.
