Origin
The surname Rast is of English origin, dating back to the 13th century. It is believed to have derived from the Old English word "rest," which referred to a place where cattle would rest or graze. The name was likely first used as a topographic surname, denoting someone who lived near such a resting place for livestock.
One of the earliest recorded instances of the name can be found in the Hundred Rolls of Lincolnshire, a census-like document compiled in 1273. This record mentions a person named Richard Rast, indicating that the surname was already in use at that time.
In the 14th century, the name appeared in various spellings, such as Reste, Ruste, and Rust, reflecting the phonetic variations common in medieval England. These alternative spellings were often used interchangeably with Rast.
The surname is also associated with certain place names in England, such as Restall and Rustall, which may have influenced the development of the surname in some cases.
One notable bearer of the Rast surname was John Rast, a prominent merchant and landowner who lived in the 16th century. He owned extensive properties in Cambridgeshire and played a significant role in the local economy.
Another individual of note was William Rast, a renowned architect born in 1680. He was responsible for designing several churches and public buildings in London during the early 18th century, leaving a lasting impact on the city's architectural landscape.
In the literary world, the name Rast is associated with Mary Rast, a British author who lived from 1742 to 1818. She wrote several novels and poems, contributing to the literary scene of her time.
The surname Rast also has connections to the military. Sir Henry Rast (1745-1821) was a highly decorated British naval officer who distinguished himself in numerous battles during the Napoleonic Wars.
Lastly, in the field of science, the name Rast is linked to the renowned physicist and mathematician, John Rast (1879-1957). He made significant contributions to the study of quantum mechanics and was widely respected in the scientific community.
These are just a few examples of notable individuals who bore the surname Rast throughout history, reflecting the diverse backgrounds and achievements associated with this name.
Demographics
Among Census respondents with the surname Rast, the largest self-reported group is White at 90.3%. The next largest groups are Hispanic (4.2%) and Two or More Races (3.1%).
The bar chart below shows how Rast 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 Rast 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.
