Origin
The surname Radcliffe has its origins in England, dating back to the medieval period. It is a locational name, derived from the place name Radcliffe, which is found in several areas of the country, including Lancashire, Yorkshire, and Greater Manchester.
One of the earliest recorded instances of the name can be found in the Domesday Book of 1086, where it appears as "Radeclive" and "Radecliue." These spellings suggest that the name may have been derived from the Old English words "read" (meaning red) and "clif" (meaning cliff or slope), possibly referring to a red cliff or hillside.
In the 12th century, the name was recorded as "Raddeclive" and "Radeclyve," and by the 13th century, it had evolved into the more recognizable form of "Radcliffe." The various spellings and variations of the name reflect the changes in language and pronunciation over time.
One notable individual who bore the Radcliffe surname was Sir John Radcliffe (1650-1714), a renowned physician and founder of the Radcliffe Library and the Radcliffe Observatory in Oxford. Another prominent figure was Thomas Radcliffe, 3rd Earl of Sussex (1526-1583), who served as Lord Lieutenant of Ireland during the reign of Queen Elizabeth I.
In the literary world, Ann Radcliffe (1764-1823) was a pioneering writer of Gothic fiction, known for her influential novels such as "The Mysteries of Udolpho" and "The Italian." Her works significantly contributed to the development of the Gothic genre.
Sir George Radcliffe (1593-1657) was a notable English lawyer and politician who served as a Member of Parliament during the English Civil War. He was a staunch Royalist and played a significant role in the events leading up to the conflict.
Another individual of note was Alexander Radcliffe (1775-1840), a British explorer and cartographer who surveyed and mapped large portions of North America, including the Canadian Arctic and the Great Lakes region.
The Radcliffe surname has been borne by many other notable figures throughout history, including politicians, academics, military leaders, and artists, reflecting its widespread distribution and long-standing presence in various parts of England and beyond.
Demographics
Among Census respondents with the surname Radcliffe, the largest self-reported group is White at 83.2%. The next largest groups are Black (8.9%) and Two or More Races (3.5%).
The bar chart below shows how Radcliffe 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 Radcliffe 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.
