Origin
The surname LORENZO originated in Italy during the Middle Ages. It is derived from the Latin name Laurentius, which means "from Laurentum," an ancient city near Rome. The name was also associated with the laurel tree, a symbol of victory and honor in ancient Rome.
One of the earliest recorded instances of the surname LORENZO can be found in the Codex Diplomaticus Cavensis, a collection of medieval documents from the Cava de' Tirreni monastery in Campania, Italy, dating back to the 11th century. The name was particularly common in central and southern Italy, including regions like Lazio, Campania, and Basilicata.
In the 13th century, the LORENZO family was prominent in the city of Florence, where several members held important positions in the government and the arts. One notable figure was Pietro LORENZO, a Florentine painter who lived from around 1230 to 1310 and contributed to the decoration of the Basilica of Santa Maria Novella.
Another notable bearer of the LORENZO surname was Niccolò LORENZO, a Renaissance philosopher and humanist from Padua, who lived from 1429 to 1501. He was known for his translations of ancient Greek texts and his contributions to the study of rhetoric.
In the 16th century, Juan LORENZO, a Spanish explorer and conquistador, was one of the first Europeans to explore the interior of modern-day Venezuela. He led several expeditions between 1530 and 1535, establishing settlements and making contact with indigenous populations.
During the 17th century, the LORENZO family had a presence in the Kingdom of Naples, where they held land and titles. One prominent member was Tommaso LORENZO, a nobleman and military officer who served as the governor of Salerno from 1665 to 1672.
Over the centuries, the LORENZO surname has spread across Italy and beyond, with variations in spelling such as Laurenzi, Laurenti, and Laurentis. The name has also been adopted by individuals of other nationalities, particularly in Spanish-speaking countries, where it has been influenced by the Spanish pronunciation of the name.
Demographics
Among Census respondents with the surname Lorenzo, the largest self-reported group is Hispanic at 68.7%. The next largest groups are White (17.6%) and Asian/Pacific Islander (9.8%).
The bar chart below shows how Lorenzo 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 Lorenzo 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.
