Origin
The surname "Mull" is of English origin and dates back to the medieval period. It is believed to have derived from the Old English word "mul," which referred to a small hill or a bare promontory. This suggests that the name may have originally been used as a topographic surname, describing a person who lived near or on a small hill or promontory.
The earliest recorded instances of the name can be found in various historical records from the 13th and 14th centuries. For example, the Hundred Rolls of 1273 mention a John de la Mulle, while the Subsidy Rolls of 1327 list a Richard atte Mulle. These early spellings, such as "de la Mulle" and "atte Mulle," indicate that the name was originally associated with a specific location or landmark.
During the medieval period, the name was often spelled in various ways, including "Mull," "Mulle," "Mole," and "Molle." This variation in spelling was common at the time due to the lack of standardized spelling conventions and the influence of regional dialects.
Throughout history, there have been several notable individuals with the surname "Mull." One such person was Sir John Mull (c. 1470-1538), who served as a member of the Privy Council under King Henry VIII. Another notable figure was Thomas Mull (1598-1672), a prominent English lawyer and member of the Long Parliament during the English Civil War.
In the literary world, George Mull (1785-1861) was a Scottish poet and writer who wrote several works celebrating Scottish culture and traditions. Similarly, John Mull (1868-1940) was an American author and journalist known for his contributions to the outdoor literature genre.
One of the earliest recorded instances of the surname "Mull" being associated with a place name is the village of Mull in Derbyshire, England. This village likely derived its name from the Old English word "mul," further reinforcing the connection between the surname and its topographic origins.
Other notable figures with the surname "Mull" include William Mull (1619-1680), an English mathematician and astronomer, and Robert Mull (1733-1808), a Scottish painter known for his landscapes and portraits.
Demographics
Among Census respondents with the surname Mull, the largest self-reported group is White at 83.1%. The next largest groups are Black (7.9%) and Two or More Races (3.6%).
The bar chart below shows how Mull 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 Mull 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.
