Origin
The surname Dudley originated in England during the Anglo-Saxon period. It is a habitational name, derived from the place name Dudley, which comes from the Old English words 'dud' meaning 'hill' and 'leah' meaning 'a clearing in a wood'.
The Domesday Book of 1086 records a place called 'Duddelei' in Worcestershire, which is believed to be the earliest recorded form of the name. This suggests that the Dudley surname was already in use by this time.
One of the earliest recorded bearers of the Dudley surname was Roger de Dudley, who was mentioned in the Pipe Rolls of Staffordshire in 1199. The Pipe Rolls were financial records kept by the English Crown.
The Dudley family rose to prominence in the late Middle Ages. John Dudley, 1st Duke of Northumberland (c.1504-1553), was a prominent figure during the reign of Edward VI and was executed for his involvement in the attempt to place Lady Jane Grey on the throne.
Another notable Dudley was Robert Dudley, 1st Earl of Leicester (1532-1588), a favorite of Queen Elizabeth I. He was a renowned courtier, diplomat, and military commander, and was rumored to be a potential suitor for the Queen.
Sir Christopher Dudley (1532-1597) was a notable explorer and navigator. He was the first Englishman to lead an expedition in search of the Northwest Passage in 1576-1578.
The name Dudley has also been associated with several place names in England, such as Dudley Castle, a medieval castle located in the town of Dudley in the West Midlands.
Other notable historical figures with the surname Dudley include Sir Robert Dudley (1573-1649), a mathematician and navigator who established the first British colony in the Caribbean, and Dud Dudley (1599-1684), an English metallurgist and entrepreneur who pioneered the use of coal in the smelting of iron.
Demographics
Among Census respondents with the surname Dudley, the largest self-reported group is White at 63.8%. The next largest groups are Black (26.6%) and Two or More Races (4.6%).
The bar chart below shows how Dudley 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 Dudley 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 Dudley (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.
