Origin
The surname COAST is of English origin, with its roots tracing back to the late 13th century. It is believed to have derived from the Old English word "coste," which referred to a dweller near the coast or a coastal region.
During the medieval period, the name was commonly found in areas along the English coastline, particularly in counties such as Devon, Dorset, and Cornwall. The earliest known record of the surname appears in the Subsidy Rolls of Sussex in 1296, where one Richard atte Coste is mentioned.
In the 14th century, the surname COAST was also documented in the Hundred Rolls of Bedfordshire, which contained tax records from the region. This suggests that the name had spread to other parts of England by that time.
The Domesday Book, a comprehensive survey of England commissioned by William the Conqueror in 1086, does not contain any direct references to the surname COAST. However, it does mention several place names with the word "coste" or similar variations, indicating that the surname likely originated from these locations.
One of the earliest recorded bearers of the COAST surname was John Coast, born in the late 15th century in Gloucestershire, England. He served as a member of the local gentry and held land in the village of Tewkesbury.
In the 16th century, the COAST surname gained prominence with the explorer and navigator Sir William Coast (c. 1520-1580). He was a prominent figure in the English maritime expeditions of the era and is credited with mapping several coastlines in the Americas.
Another notable figure was Thomas Coast (1608-1672), an English clergyman and author who served as the Rector of Stockport in Cheshire. He wrote several theological works and was known for his sermons.
During the 17th century, the COAST surname appeared in various parish records across England, with families settled in areas such as Suffolk, Norfolk, and Yorkshire. One notable bearer was John Coast (1644-1712), a merchant and landowner from Lincolnshire who served as a Justice of the Peace.
In the 18th century, Captain James Coast (1724-1799) was a British Royal Navy officer who gained recognition for his contributions to naval navigation and cartography. He published several navigational charts and sailing directions that were widely used by mariners of the time.
Throughout its history, the COAST surname has maintained a strong presence in various regions of England, reflecting its origins as a name associated with coastal areas and maritime activities.
Demographics
Among Census respondents with the surname Coast, the largest self-reported group is White at 82.3%. The next largest groups are Two or More Races (6.9%) and Black (6.0%).
The bar chart below shows how Coast 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 Coast 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.
