Origin
The surname MUNDY has its origins in medieval England, originating from the Anglo-Norman French word "munde," meaning "world" or "secular." It was initially used as a nickname for a worldly or secular person, particularly a clergyman who lived outside of monastic life.
The earliest known record of the MUNDY surname dates back to the 13th century, appearing in the Hundred Rolls of Oxfordshire in 1273 as "Willelmus Mundi." This suggests that the name was already well-established in England by this time.
In the 14th century, the name appeared in various forms, such as "Mundy," "Mundi," and "Monde," reflecting the variations in spelling and pronunciation common in medieval times. One notable early bearer of the name was John Mundy, a Member of Parliament for Derbyshire in 1388.
The MUNDY surname is also associated with several place names in England, such as Mundayborough in Norfolk, Mundy in Derbyshire, and Mundy's Farm in Hertfordshire. These place names likely derived from individuals bearing the MUNDY surname who once owned or resided in those areas.
One of the earliest recorded instances of the MUNDY surname in a historical document is in the Domesday Book of 1086, where it appears as "Munderic" and "Mundrie." This further solidifies the name's Anglo-Norman roots and its presence in England during the Norman Conquest.
Throughout history, several notable individuals have borne the MUNDY surname, including:
1. Sir John Mundy (1552-1625), an English landowner and Member of Parliament for Derbyshire.
2. Peter Mundy (1600-1667), an English merchant and traveler who documented his journeys to Asia in the 17th century.
3. George Basil Mundy (1808-1876), an English novelist and travel writer best known for his book "Our Antipodes" about his travels in Australasia.
4. Godfrey Mundy (1804-1860), an English cricketer who played first-class cricket for Cambridge University and Nottinghamshire.
5. Rodney Mundy (1923-2001), a South African-born British author and journalist who wrote extensively on military history and warfare.
The MUNDY surname has a rich history rooted in medieval England, originating as a nickname for a worldly or secular person. Its presence in historical records, place names, and notable individuals highlights its enduring legacy and significance throughout the centuries.
Demographics
Among Census respondents with the surname Mundy, the largest self-reported group is White at 78.3%. The next largest groups are Black (13.1%) and Two or More Races (4.0%).
The bar chart below shows how Mundy 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 Mundy 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.
