Origin
The surname "TUN" has its origins in England, where it first emerged in the 13th century. It is believed to have derived from the Old English word "tun," which means an enclosure or a town.
In medieval England, the name "TUN" was often used to refer to people who lived in or were associated with a particular town or village. It was a descriptive surname, indicating the place of residence or origin of the bearer.
One of the earliest recorded instances of the surname "TUN" can be found in the Hundredorum Rolls of 1273, which were records of landholders and tenants in various counties of England. The name appears in these rolls as "de Tun," reflecting the Norman influence on English surnames during that period.
The Domesday Book, compiled in 1086 by order of William the Conqueror, mentions several places with the prefix "Tun," such as Tuncroft and Tunbridge, which may have contributed to the development of the surname.
Notable individuals who bore the surname "TUN" throughout history include:
1. William de Tun (c. 1250 - 1320), a prominent landowner and member of the gentry in Gloucestershire, England.
2. John Tun (c. 1400 - 1475), a merchant and alderman of the City of London, known for his involvement in the wool trade.
3. Alice Tun (c. 1470 - 1540), a philanthropist and benefactor who founded a school for underprivileged children in the village of Tunbridge Wells, Kent.
4. Thomas Tun (c. 1560 - 1628), a celebrated playwright and poet during the Elizabethan era, best known for his satirical works.
5. Elizabeth Tun (c. 1630 - 1692), a Puritan writer and diarist who documented her religious experiences in her journal, which provided valuable insights into 17th-century English society.
Over time, variations of the spelling emerged, including "Tunn," "Tunne," and "Tonne," reflecting regional dialects and linguistic changes. Some of these variants may have been influenced by the surnames derived from place names like Tunbridge Wells or Tunstall.
Demographics
Among Census respondents with the surname Tun, the largest self-reported group is Asian/Pacific Islander at 82.9%. The next largest groups are Hispanic (11.3%) and White (3.5%).
The bar chart below shows how Tun 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 Tun 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.
