Origin
The surname Sladen is of English origin and can be traced back to the late 12th century. It is believed to have originated from the Old English words 'slæd', meaning 'valley', and 'denu', meaning 'valley'. This suggests that the name may have initially been a locational name, referring to someone who resided in a particular valley or dell.
The earliest known record of the name appears in the Pipe Rolls of Yorkshire in 1204, where it is recorded as 'de Sladeburn'. This spelling variation, which combines the elements 'slæd' and 'burna' (stream), reinforces the connection to a geographical location.
In the Domesday Book of 1086, there are several entries for places with similar names, such as Sladeburne in Worcestershire and Sledborne in Lincolnshire, which could have been the original homesteads of those bearing the surname Sladen.
One of the earliest known individuals with this surname was John Sladen, who was listed in the Subsidy Rolls of Sussex in 1327. Another early record is that of William Sladen, born around 1430 in Gloucestershire, whose descendants later settled in the neighboring county of Oxfordshire.
A notable figure in history was Sir John Sladen (1566-1647), an English lawyer and politician who served as a Member of Parliament for Reading in the early 17th century. He was also appointed as a Justice of the Peace for Berkshire.
During the English Civil War, Captain Edward Sladen (1601-1670) was a Royalist officer who fought for King Charles I and was later imprisoned for his loyalty to the crown.
In the 18th century, Sir Hans Sloane (1660-1753), an English physician and naturalist, is considered one of the most prominent individuals with the surname Sladen. He was a renowned collector of natural curiosities, and his collection formed the foundation of the British Museum.
The surname Sladen has also been associated with several place names in England, such as Sladengreen in Buckinghamshire, Sladefield in Yorkshire, and Sladehouse in Lancashire. These locations may have been named after individuals bearing the surname or vice versa.
Demographics
Among Census respondents with the surname Sladen, the largest self-reported group is White at 87.4%. The next largest groups are Two or More Races (5.0%) and Black (4.2%).
The bar chart below shows how Sladen 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 Sladen 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.
