Origin
The surname SWINNEY is an English toponymic surname derived from a place name meaning "swine pasture" or "pig meadow". It originates from the Old English words "swin" meaning swine or pig, and "ey" meaning an island or meadow. The earliest recorded spelling of the name is found in the Domesday Book of 1086, where it appears as "Swinei".
The name is believed to have originated in the county of Northamptonshire, where there are several places that may have given rise to the surname, such as Swinford, Swinnerton, and Swinstead. These place names all share the same root words as the surname SWINNEY.
One of the earliest recorded bearers of the surname was John Swinney, who was mentioned in the Pipe Rolls of Lincolnshire in 1202. Another early record is that of William Swinney, who was listed in the Subsidy Rolls of Worcestershire in 1327.
In the 16th century, the surname appears to have been particularly concentrated in the counties of Northamptonshire, Warwickshire, and Staffordshire. Notable bearers from this period include Richard Swinney, who was born in Warwickshire in 1542, and Thomas Swinney, a merchant from Staffordshire who was born in 1578.
During the 17th century, the name began to spread more widely across England. One prominent individual was Sir John Swinney, a member of Parliament for the borough of Southwark, who was born in 1625 and died in 1697.
In the 18th century, a branch of the Swinney family established themselves in Scotland, where the name was sometimes spelled as "Swinnie". One notable Scottish bearer was Alexander Swinnie, a philosopher and professor at the University of Aberdeen, who was born in 1735 and died in 1803.
Other notable individuals with the surname SWINNEY throughout history include William Swinney, an English soldier who fought in the Napoleonic Wars and was awarded the Waterloo Medal, born in 1793; and George Swinney, a British explorer and naturalist who traveled extensively in South America in the late 19th century, born in 1859 and died in 1912.
Demographics
Among Census respondents with the surname Swinney, the largest self-reported group is White at 70.5%. The next largest groups are Black (21.6%) and Two or More Races (3.6%).
The bar chart below shows how Swinney 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 Swinney 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.
