Origin
The surname POOL has its origins in the English language and can be traced back to the medieval period. It is believed to have derived from the Old English word "pol," which referred to a small body of water or a pool. This word was also used to describe people who lived near a pool or a pond.
One of the earliest recorded instances of the surname POOL can be found in the Domesday Book, a comprehensive survey of land ownership in England commissioned by William the Conqueror in 1086. This suggests that the name was already in use by the 11th century.
The surname POOL was particularly prevalent in areas of England where bodies of water, such as pools or ponds, were abundant. This included regions like Lancashire, Cheshire, and Yorkshire. Over time, the name also became associated with certain place names, such as Pooltown or Poolhampton, which further solidified its connection to bodies of water.
During the Middle Ages, the spelling of the surname varied, with forms like "Poole," "Pole," and "Poul" being common. This was due to the lack of standardized spelling conventions at the time.
One notable individual with the surname POOL was Sir William Pool (c. 1380-1439), a prominent English politician who served as the Speaker of the House of Commons during the reign of Henry VI. Another notable figure was John Pool (c. 1504-1558), an English Catholic priest and martyr who was executed during the reign of Queen Mary I for his religious beliefs.
In the 17th century, the name was also associated with the Pool family of Shropshire, England. This family produced several notable figures, including Sir John Pool (1613-1685), a Royalist officer during the English Civil War, and Roger Pool (1639-1708), a lawyer and Member of Parliament.
As the centuries progressed, the surname POOL continued to spread across England and beyond, with individuals bearing this name making their mark in various fields, including literature, science, and the arts. Some notable examples include Maria Pool (1773-1839), an English author and poet, and John Pool (1826-1884), an English zoologist and paleontologist.
Overall, the surname POOL has a rich history that can be traced back to the medieval period in England, where it was closely associated with bodies of water and certain geographical locations. Despite its humble origins, the name has been carried by many notable individuals throughout history, leaving a lasting impact on various aspects of society.
Demographics
Among Census respondents with the surname Pool, the largest self-reported group is White at 79.1%. The next largest groups are Black (7.8%) and Hispanic (7.1%).
The bar chart below shows how Pool 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 Pool 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.
