Origin
Meaning and origin of Manzi
The surname Manzi has its origins in Italy, specifically in the region of Tuscany. It is believed to have emerged during the medieval period, around the 12th or 13th century. The name is derived from the Italian word "manzo," which means "ox" or "bullock." This suggests that the surname may have originally referred to someone who worked with oxen, such as a farmer, a herder, or a cattle trader.
One of the earliest recorded instances of the name Manzi can be found in the famous Florentine chronicle known as the Cronica di Giovanni Villani, written in the 14th century. The chronicle mentions a family called the Manzi who were prominent citizens of Florence during that time.
In the 15th century, there is a record of a Leonardo Manzi who was a renowned artist and architect. He is best known for his work on the Basilica of San Petronio in Bologna, where he designed the intricate marble facade.
During the Renaissance period, the Manzi family produced several notable figures. In the 16th century, Bartolomeo Manzi (1494-1576) was a renowned humanist scholar and poet from Siena. He was a member of the Accademia degli Intronati, a prestigious literary academy in Siena.
Another prominent figure with the surname Manzi was Girolamo Manzi (1547-1618), an Italian jurist and legal scholar from Lucca. He was a professor of law at the University of Padua and authored several influential works on legal theory and practice.
In the 18th century, Giuseppe Manzi (1765-1831) was a distinguished Italian writer and educator from Forlì. He is best known for his literary works, particularly his poetry and translations of classical Greek and Latin texts.
While the surname Manzi originated in Italy, it has since spread to other parts of the world, particularly through Italian immigration. However, its roots can be traced back to the medieval and Renaissance periods in Italy, where it was associated with various notable figures in the fields of art, architecture, literature, and law.

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 Manzi surname at the time of the 2020 Census, not any inherent property of the name itself.

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Manzi (2000, 2010, 2020).
Does the Census include every surname?
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.
Why don't the ancestry percentages always add up to exactly 100%?
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.
