Origin
The surname "MUSTY" is believed to have originated in England during the late medieval period, around the 13th or 14th century. It is thought to be derived from the Old English word "mustig," which means "musty" or "stale-smelling." This term was likely used as a descriptive nickname for someone who lived in damp or poorly ventilated conditions.
One of the earliest known references to the name can be found in the Subsidy Rolls of Worcestershire from 1327, where a person named Richard Musty is listed. This suggests that the name was already in use by the early 14th century, particularly in the West Midlands region of England.
In the 15th century, the surname appeared in various records across different counties in England, such as the Lay Subsidy Rolls of Wiltshire from 1451, where a John Musty is mentioned. The name was also found in the Feet of Fines for Essex from 1487, which recorded a transaction involving a Thomas Musty.
During the 16th century, the surname underwent some variations in spelling, including "Mustie" and "Mustye." One notable bearer of the name was John Mustie, who was born in Gloucestershire, England, around 1520 and later became a Protestant martyr, being burned at the stake in 1557 during the reign of Queen Mary I.
In the 17th century, the surname continued to be documented in various parish records and other historical documents. For instance, the Hearth Tax records of 1662 for Staffordshire listed a William Musty as a householder in the town of Wolverhampton.
Another notable figure with the surname was Thomas Musty, a merchant and landowner who lived in Gloucestershire in the late 17th century. He was involved in several legal disputes over property rights and left a substantial estate upon his death in 1698.
In the 18th century, the surname appeared in various genealogical records and parish registers across England. One notable bearer was John Musty, a clockmaker born in London in 1723, who became well-known for his intricate and ornate clocks.
As the surname spread throughout England and beyond, it inevitably underwent further variations in spelling, including "Musti," "Mustey," and "Mustye." However, the original spelling of "MUSTY" remained the most common form throughout its history.
Demographics
Among Census respondents with the surname Musty, the largest self-reported group is White at 78.1%. The next largest groups are Asian/Pacific Islander (11.4%) and Two or More Races (4.4%).
The bar chart below shows how Musty 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 Musty 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.
