Origin
The surname Oswald is of Anglo-Saxon origin, deriving from the Old English personal name Ōsweald, which is composed of two elements: ōs meaning 'divine' or 'God', and weald meaning 'power' or 'ruler'. The name essentially translates to 'Divine Power' or 'Ruler by God'.
The name Oswald is closely associated with the historical figure of Saint Oswald, the King of Northumbria from 634 to 642 AD. He was renowned for his efforts in promoting Christianity and is credited with the establishment of several monasteries, including Lindisfarne. Saint Oswald's name appears in the Venerable Bede's Ecclesiastical History of the English People, a seminal work written in the early 8th century.
One of the earliest recorded instances of the surname Oswald can be found in the Domesday Book of 1086, where it is spelled as 'Oswald' and 'Oswold'. The name is mentioned in various counties across England, suggesting its widespread use during the Norman conquest.
The surname Oswald has been associated with several notable individuals throughout history. One such figure is Thomas Oswald (c. 1556-1642), an English Catholic priest and martyr who was executed for his religious beliefs during the reign of King James I.
In the 18th century, Richard Oswald (1705-1784) was a British merchant and politician who played a pivotal role in the negotiations that led to the Peace of Paris in 1783, effectively ending the American Revolutionary War.
Another notable bearer of the surname was Sir Peter Oswald (1892-1971), a British diplomat and civil servant who served as the Governor of New South Wales, Australia, from 1957 to 1962.
The surname Oswald has also been associated with various place names, particularly in England. For instance, Oswald's Ash in Worcestershire is believed to derive its name from the Old English words 'Ōsweald' and 'æsc', referring to an ash tree associated with an individual named Oswald.
Throughout its history, the surname Oswald has undergone various spellings, including Oswald, Oswold, Oswell, and Oswall, reflecting the linguistic variations and regional influences across different parts of England and beyond.
Demographics
Among Census respondents with the surname Oswald, the largest self-reported group is White at 92.2%. The next largest groups are Hispanic (3.1%) and Two or More Races (2.7%).
The bar chart below shows how Oswald 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 Oswald 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 Oswald (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.
