Origin
Meaning and origin of Renzi
The surname Renzi is of Italian origin, with its earliest recorded use dating back to the 14th century in the region of Tuscany. It is derived from the Italian word "renzo," which means "laurel wreath" and was often used as a nickname for those with the first name Lorenzo.
One of the earliest documented instances of the name Renzi can be found in the Florentine tax records of 1427, where a certain Matteo di Renzo is listed as a resident of the city. This suggests that the name was firmly established in the Tuscan region by the early 15th century.
During the Renaissance period, several notable individuals bearing the surname Renzi emerged in Italy. One such figure was Andrea Renzi, a renowned architect and sculptor who lived from 1512 to 1585. He is best known for his work on the Palazzo Pitti in Florence and the Basilica of Santa Maria Maggiore in Rome.
Another prominent figure from this era was Giulio Renzi, a 16th-century poet and playwright from Ancona. His most famous work, "La Pazzia d'Isabella," a comedy in verse, was widely acclaimed and performed throughout Italy during his lifetime (1529-1592).
In the 17th century, a branch of the Renzi family settled in the city of Naples, where they became involved in the maritime trade. One member of this family, Tommaso Renzi (1611-1678), gained fame as a skilled navigator and cartographer, producing several highly regarded maps of the Mediterranean region.
Moving into the 18th century, the name Renzi continued to appear in various historical records across Italy. In 1746, a Benedetto Renzi from Siena was recorded as being a member of the Accademia dei Rozzi, a prestigious literary society dedicated to the promotion of the Sienese dialect.
Throughout the 19th and early 20th centuries, several individuals with the surname Renzi achieved notable accomplishments in various fields. Among them was Giuseppe Renzi (1819-1894), an Italian linguist and philologist known for his contributions to the study of Romance languages.
In more recent times, the most famous bearer of the name Renzi was Matteo Renzi, the former Prime Minister of Italy who served from 2014 to 2016. Born in 1975, he rose through the ranks of the Democratic Party and became one of the youngest leaders in Italy's history.
Demographics
Ancestry and ethnicity for Renzi

The bar chart below shows how Renzi 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 Renzi surname at the time of the 2020 Census, not any inherent property of the name itself.

Is this page using the latest Census data?
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 Renzi (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.
