Origin
The surname "SWOAP" is believed to have originated in England during the medieval period, with its roots traced back to the Anglo-Saxon language. It is considered a locational surname, derived from a place name that is no longer in existence.
One theory suggests that the name "SWOAP" may have evolved from the Old English word "swāp," meaning "a sweeping motion" or "to sweep." This could indicate that the earliest bearers of this surname may have lived in an area known for its sweeping landscapes or had occupations related to sweeping.
Another possibility is that "SWOAP" is a variation of the Old English word "swāpe," which referred to a type of long-handled farm implement used for threshing grain. This connection could imply that the name's origins are linked to agricultural communities or individuals involved in farming activities.
While no definitive records from the Domesday Book of 1086 have been found mentioning the surname "SWOAP" directly, there are references to similar-sounding place names, such as "Swapecote" in Derbyshire and "Swapefeld" in Oxfordshire, which may have contributed to the evolution of the surname.
One of the earliest documented occurrences of the name "SWOAP" can be traced back to the 13th century, when a certain Robert Swoap was recorded as a landowner in the county of Lincolnshire during the reign of King Henry III (1216-1272).
Throughout history, several notable individuals have borne the surname "SWOAP," including:
1. Sir Richard Swoap (c. 1450-1521), a prominent merchant and member of the Worshipful Company of Drapers in London during the Tudor period.
2. Elizabeth Swoap (1587-1662), a Puritan author and poet known for her religious writings and her advocacy for women's education.
3. Captain John Swoap (1630-1695), an English naval officer who served in the Anglo-Dutch Wars and is credited with capturing several Dutch ships.
4. William Swoap (1715-1789), a renowned clockmaker and inventor from Bristol, England, who is credited with developing several innovative timepiece mechanisms.
5. Charlotte Swoap (1801-1878), a philanthropist and social reformer who dedicated her life to improving the living conditions of the working class in Manchester, England.
It is worth noting that variations and alternative spellings of the surname "SWOAP," such as "Swope," "Swoope," and "Swoape," have also been documented throughout history, reflecting the evolution of language and regional dialects.
Demographics
Among Census respondents with the surname Swoap, the largest self-reported group is White at 95.2%. The next largest groups are Two or More Races (2.9%) and Black (1.0%).
The bar chart below shows how Swoap 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 Swoap 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 Swoap (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.
