Origin
The surname Carson has its origins in Scotland, emerging in the 13th century. It is derived from the Gaelic personal name "Carsane," which means "rocky place." The earliest known bearers of this name resided in the regions of Ayrshire and Lanarkshire.
One of the earliest historical references to the name Carson can be found in the Ragman Rolls of 1296, which lists those who swore allegiance to King Edward I of England after his conquest of Scotland. The entry "William de Carsan" is recorded in these rolls, suggesting the name's use during this time period.
In the 16th century, the Carson surname appeared in various Scottish records, including the Register of the Great Seal of Scotland, where the name was spelled as "Carsane" and "Carsoun." This indicates the name's evolution from its original Gaelic form.
The earliest recorded example of the Carson surname dates back to 1548, when a John Carson was listed in the records of the Burgh of Prestwick, located in Ayrshire, Scotland.
Throughout history, several notable individuals have borne the Carson surname. One of the most famous is Rachel Carson (1907-1964), an American marine biologist and conservationist whose book "Silent Spring" (1962) is considered a pivotal work in the modern environmental movement.
Another prominent figure is Samuel Carson (1798-1838), an American politician and lawyer who served as a United States Representative from North Carolina in the 1820s.
Sir Edward Carson (1854-1935), an Irish unionist politician and judge, played a significant role in the formation of Northern Ireland and served as the first Lord Chief Justice of Northern Ireland.
John Carson (1760-1835), an American politician and soldier, represented Virginia in the United States House of Representatives and served in the American Revolutionary War.
Christopher "Kit" Carson (1809-1868) was a renowned American frontiersman, trapper, and guide who led expeditions and military campaigns throughout the American West.
Place names and older spellings of places have also contributed to the Carson surname. For example, the town of Carson City in Nevada is named after the famous frontiersman Kit Carson.
Demographics
Among Census respondents with the surname Carson, the largest self-reported group is White at 69.0%. The next largest groups are Black (21.4%) and Two or More Races (4.6%).
The bar chart below shows how Carson 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 Carson 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.
