Origin
The surname TANK is believed to have originated in England during the Middle Ages. It is thought to be derived from the Old English word "tanc," which referred to a small pool or pond. This suggests that the name may have initially been given as a descriptive surname to someone who lived near a small body of water.
The earliest recorded instances of the surname TANK can be found in various medieval records and documents from the 13th and 14th centuries. One notable example is the appearance of the name in the Hundred Rolls of Cambridgeshire, a census-like record compiled in 1273 during the reign of King Edward I.
Throughout history, the surname TANK has undergone various spelling variations, such as Tanke, Tancke, and Taunke. These variations likely arose due to regional dialects, scribal errors, and the lack of standardized spelling conventions in earlier times.
One of the earliest known bearers of the surname TANK was John Tanke, a landowner and farmer who lived in the village of Broughton, Oxfordshire, in the late 14th century. Records from the time indicate that he was born around 1350 and lived until the early 1400s.
Another notable figure with the surname TANK was Sir William Tanke, a knight who served in the army of King Henry V during the Hundred Years' War. He fought in the Battle of Agincourt in 1415 and was later granted lands in Normandy for his service.
In the 16th century, the name TANK appears in the records of the city of London, where a merchant named Richard Tanke is mentioned in the Guild of Mercers records from 1567. He was a successful trader who dealt in various goods, including textiles and spices.
During the 17th century, the name TANK can be found in the parish records of several English counties, such as Gloucestershire and Wiltshire. One notable figure from this time was John Tanke, a clergyman who served as the rector of the parish of Swindon from 1634 until his death in 1671.
In the 18th century, the surname TANK was also found in Scotland, where a family of that name lived in the town of Kirkcaldy, Fife. One member of this family, James Tank, was a prominent merchant and shipowner who lived from 1725 to 1798.
As the centuries passed, the surname TANK continued to be found throughout various regions of England and Scotland, with some bearers of the name also migrating to other parts of the world, including North America and Australia.
Demographics
Among Census respondents with the surname Tank, the largest self-reported group is White at 79.0%. The next largest groups are Asian/Pacific Islander (13.9%) and Two or More Races (3.0%).
The bar chart below shows how Tank 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 Tank 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.
